Dr. Brian Hooker returns to discuss his latest research on aluminum exposure and its potential role in neurodevelopment. This conversation focuses on what’s newly understood, what’s often overlooked, and how parents can think more clearly about this topic. The secret this week is… Take Aluminum Exposure Seriously
Loading summary
Dr. Brian Hooker
When you look at the birth hepatitis B vaccine that has anywhere between 250 to 330 micrograms of aluminum in it. The exposure limit for aluminum through parenteral nutrition, the daily limit on aluminum exposure is 5 micrograms. But yet that same pre meat, they're injecting over 250 to 330 micrograms of aluminum to over 50 times what the limit should.
Len (Host of Autism Parenting Secrets)
If you're a parent of a child with autism, you are being called to rise with love, courage, and clarity. This journey isn't easy, and most parents aren't equipped, but you can be. This podcast is your invitation to rise higher because how you navigate matters. I'm Len, and this is Autism Parenting Secrets, where you become the parent your child needs now.
Glenn (Co-host or Interviewer)
Hello and welcome.
Len (Host of Autism Parenting Secrets)
It's Len, and I'm really glad you're here.
Glenn (Co-host or Interviewer)
And today we're going to dive into an important and timely topic, aluminum exposure. And it's something that most parents don't think much about, and the ones that do think about it tend to be told not to worry about it. But there really is more to understand here on this topic because it's not just about where aluminum may show up, but it's about what can happen after it enters the body and especially when it comes to the immune function and the brain. So this is a topic that's worth diving into. And my guest is a friend of the show, Dr. Brian Hooker. He is back. He is the chief science officer at Children's Health Defense, and he's been on several times before to help us unpack complex topics and to kind of crystallize the insights in a clear and grounded way. So, so in this conversation, that's what we're going to do about the topic of aluminum. What's known, what's often overlooked, and what it may mean for our kids. The secret this week is take aluminum exposure seriously. And, Brian, I'm delighted to welcome you back.
Dr. Brian Hooker
Well, thanks so much, Lynn. It's always great to be back, and I don't know how to follow an introduction like that. The fact that we're talking during Autism Awareness Month, you know, obviously autism parenting secrets, that's what you talk about every podcast, and I'm so thankful for it. But this is different. This is special. You know, I'm looking forward, and I really feel like this is the year that we expand the audiences, we reach new audiences, and that more people hear the word, get the word, and then also are able to help their kids in a way that they've never been able to help them before.
Glenn (Co-host or Interviewer)
It's an incredible period right now where there's so much opportunity for things that have been known for a while to become better known. And again, as you're thinking about autism and what might be some of the drivers behind how your child's exhibiting the challenges they may be experiencing, this is a really important topic, very relevant for me and my son's history. I know it's relevant for you and your son as well, Brian. And again, the concept of heavy metals and toxicity, we're all aware of it to some degree, but how significant of a role could it be playing not only in the history of our kids, but like in terms of what's happening now that people who are looking to have children, you know what would be useful for them to better understand. And I know you're a science guy, you do research, you just did a study. And I'd love for you to talk more about that because we're beyond guessing now that toxicity in the form of metals, particularly in this case, we're going to talk about aluminum or whether it's mold toxicity and these other toxins that are out there. Yeah, they all can play a role. So it's about not fear and being worried about everything. It's just about understanding the reality of what might be happening so that parents can make better decisions. So with that, tell me a little bit about the research you've done over the last couple decades and especially recently, what you've uncovered that is novel and useful to share with other parents.
Dr. Brian Hooker
Well, I really appreciate that. We have looked specifically at aluminum adjuvants in vaccines. We want to look at probably the most, to me, aggressive form of aluminum exposure. When you look at the birth hepatitis B vaccine that has anywhere between 250 to 330 micrograms of aluminum in it. The exposure limit for aluminum through parenteral nutrition, that's when in the NICU when they're giving nutrition to preemies and it's going intravenously, the daily limit on aluminum exposure is 5 micrograms. But yet that same preemie they're injecting intramuscularly over 250 to 330 micrograms of aluminum. So what that's, you know, it's over 50 times what the limit should be on that parenteral nutrition. So we, we felt like that was important to look at you, you know, then you come back for a, well, baby checkup. At two months you can get upwards to seven vaccines. That exposure is over a thousand micrograms. Of aluminum in the form of aluminum salts, aluminum sulfate and aluminum phosphate. So that's where we started. And aluminum adjuvants are unique because they are injected into the body not as single molecules, single soluble molecules that are floating around, you know, the aluminum salts, but they're injected as nanoparticles. And so they're larger particles and they can deliver directly to the brain. It has been established the pathway. There's an immune cell type called macrophages. Macrophages are some of the first lines of defense. And you know, when something is injected, something is ingested, something, you know, specifically gets into the bloodstream, gets into the extracellular fluid or gets into the cells, then macrophages will come and pick it up. Well, macrophages, then once they at the site of injection, get these aluminum nanoparticles in them. They'll go to the lymph nodes then and redistribute. And some of them can end up in the brain because macrophages can eclipse the blood brain barrier. They're designed to go into the brain. It used to be thought that the brain was an organ that was termed immunologically privileged, meaning that the immune system just completely ignored the brain and nothing could get in, nothing could get out. Nothing is further than the truth from the truth than that. Now we know that there's an entire immune system in the brain with immune cell types called microglia and astroglia, astrocytes. And these are the functioning immune cells of the brain. Well, it's already been established by Christopher Exley. He's actually done two publications where he's looked at autistic cadavers versus neurotypical cadavers. And he sees upwards five to ten times the aluminum content in the brain in general and in all portions of the brain as compared to non autistic controls. So we know that there's something there. The research team that I put together actually embarked on a study. We want to look and see outside of mercury, what were the most insidious vaccine components? Everything came back. Aluminum adjuvants. Everything came back. So we know that that is a major contributor to, to the toxicity and the etiology of how autism can start. I'm not saying that it's not necessary and sufficient. It doesn't negate the fact that there are other things that can cause autism. And certainly there are autistic children that have never received a vaccine. So it doesn't negate that. But we saw overwhelmingly in the literature that we searched, when we put together this latest publication, we actually searched over A thousand different papers to see the connection between vaccines and autism. And again, the overwhelming response. And about 160 of those publications had to deal with aluminum adjuvants.
Glenn (Co-host or Interviewer)
So there's a whole laundry list of possible adjuvants. Aluminum's one of them, there's others, which, whether it's mercury, there's a laundry list of possible ones. And you've looked at all that and what I think you're suggesting is that the case for aluminum, of that being problematic and perhaps a more significant contributor to what might manifest as signs of being on the autism spectrum, that that one adjuvant seems to be rising to the top. Is that fair to say?
Dr. Brian Hooker
Correct. Out of all vaccine components. So when you look at live viruses, when you look at adjuvants, when you look at additives like formaldehyde that's used to denature viruses, polysorbate 80, which is a detergent, the thing that really popped up as being the most problematic in, in an era where we did not consider mercury, you took mercury out of the picture because we were following Secretary Kennedy's lead regarding thimerosal being out of vaccines and nobody to me that has been established. Mercury is a neurotoxic. It is a neurotoxin. If you put a neurotoxin in your body, then there are going to be neurological ramifications, including autism. So we took that one off the
Glenn (Co-host or Interviewer)
table and the level or the amount doesn't really matter. It's toxic.
Dr. Brian Hooker
It is toxic. There may be a toxicity threshold to aluminum where, okay, you can ingest this, you know, microgram, nanogram level of aluminum that isn't toxic. But quite honestly, Len, it just does damage. It introduces so much oxidative stress in the brain. When it gets in the brain, that is going to do frank neuronal damage.
Glenn (Co-host or Interviewer)
And you mentioned Chris Exley. I mean, it's not like you just, you're consulting some random scientist who's like doing some studies. I mean, he is possibly the world's most, the best authority on aluminum toxicity.
Dr. Brian Hooker
Would you say that exactly. When we put together the paper. Chris Shaw from University of British Columbia is one of the co authors of the paper. We're actually revising it a bit. It's now a preprint and you can go to zenodo Z-E-N-O-O.org and just type in aluminum autism and search for it. Then that paper will pop up and I'll give you the exact address of the paper for the show notes. But yeah, we consulted with Exley. We consulted with Chris Shaw. We are in the process of revising the paper because we consulted with Lucia, Tom Lenovich, and we met Kripo, who are all these just luminaries in the aluminum toxicity world. So not only do we know that aluminum can go directly into the brain, and when it goes into the brain, then it activates several different small protein molecules called cytokines. And the main ones are Interleukin 6 and TNF Alpha. Those are pro inflammatory, so they directly cause inflammation. So the inflammation comes in through it promotes an imbalanced T cell response. T cells are not the innate immune system, but they're a quieter immune system. So it imbalances the T cell response to what is called TH17. Okay. And TH stands for T helper cell. T helper 1s are more anti inflammatory. T helper 2 are more pro inflammatory. And then there's this odd D Very, very pro inflammatory. And we dovetailed this with some groundbreaking work that came out of Harvard medical school in 2019 that actually showed how these T helper cells will directly enter into the brain and they will damage astrocytes. Okay. And this groundbreaking paper, it's Distasio et al, 2019. I will get you the name of the journal in the show notes. They're the first publication. They look at autistic cadavers again versus control cadavers. And they saw that astrocytes, immune cells in the brain, were directly being attacked by these T cells. And these T cells then were causing astrocytes to bleb. When astrocytes die, they make these little subcellular particles called blebs. And up to that point, it was not really known that there was frank brain damage in autism. That was the first publication that showed it. There were a lot of theories about cell stasis. There were a lot of theories. I'm not negating those, but this groundbreaking work showed that these T cells, when they get into the brain, T helper cells, T helper 17, that they cause a shift in. In sort of a different type of T cells that are more. The cytotoxic T cells, the cytotoxic T cells then turn on these brain cells called astrocytes. All of that is hastened by aluminum entering into the body. And that mechanism doesn't necessarily require aluminum to get into the brain. In addition to that, we know that aluminum will directly deliver in the brain, and once it does deliver in the brain is these nanoparticles, then it will directly attack.
Glenn (Co-host or Interviewer)
Got it. Got it.
Dr. Brian Hooker
So we've made the connection Two different ways that these aluminum adjuvants cause brain damage, brain dysfunction that we know is consistent with autism and autism spectrum disorder. Right.
Glenn (Co-host or Interviewer)
And you would never see that. That's why the cadavers is the only way to see what actually is reaching the brain. Right. Because the school of thought would say, going back to how you started with the hep B, right, and at birth, that yes, okay, yeah, there's aluminum. It's a small amount. It's not. It's not doing anything. It can't do anything. So even though what you said is egregious in terms of how much it exceeded the standard levels. So just go back to that. What was the argument, or what is the argument about why those extremely high levels are okay?
Dr. Brian Hooker
The argument basically are bad epidemiology. So you look at the studies that are being used to support the safety of aluminum adjuvants in vaccines, and they are all epidemiological studies, all really population based studies. And the pinnacle was a paper that came out in 2025 by Anderson et al. It came out of Denmark. It actually came out from a vaccine developer, the Statin Serum Institute. They used to be a vaccine manufacturer. They closed their manufacturing arm, but they still develop vaccines. And so there's an institutional conflict of interest for individuals that are making, designing vaccines to test out a vaccine component that is in their vaccines and say that no, it doesn't cause autism. So there was a huge conflict of interest. In addition, when this paper rolled out, it rolled out on July 15, 2025, it had supplemental data tables. And the supplemental data tables that were rolled out on July 15 showed that there was no problem. Well, those tables were swapped out quietly two days later on July 17. And all of a sudden, when you look at the supplemental tables, you can see that in specific instances, the way that they studied aluminum, that it was tied to autism, it was tied to autism spectrum disorder, it was tied to Asperger's syndrome, which was still a syndrome that was coded. This was the national registry of research in Denmark. So it was medical records for literally all of the children in Denmark. And so there were all these statistically significant ties showing that, you know, aluminum was associated with these disorders. But yet when you read the abstract of the paper, it was inconsistent. The verbiage of the paper was inconsistent with what their supplemental tables said. So essentially they lied. You know, there's no way around it. In addition, in this particular paper, they did a statistical trick. They looked at children that had a large amount of aluminum versus a control group that had just a little less aluminum. They did not have a zero aluminum exposure control group. Okay. And they did have the opportunity. If they looked at unvaccinated children or children that were not vaccinated during that particular time period within, you know, the first months of life, then they could have easily come up with a zero exposure control group. But when you look at, when you start to slice and dice and you look at this very, very minute difference between the experimental group and the control group, then that tends to wash out your signal. The thing that was stunning to us, me and my coworker at Children's Health Defense, senior research scientist Carl Jablonowski. He's the one that found the supplement when even though they were looking at minute differences in aluminum exposure, there was still a statistically significant relationship among the higher exposure group for autism, autism spectrum disorder and Asperger's.
Glenn (Co-host or Interviewer)
And you mentioned about the study and the kind of summary doesn't match the data. That's something that you see quite frequently, right, With a lot of studies where if you really look at the data, it doesn't support what the conclusion was. So that's, that's more common than we'd like to think.
Dr. Brian Hooker
Absolutely. And these researchers, the lead researcher on this study was Dr. Anders Havid. Dr. Havid has been publishing studies supporting vaccination and negating vaccine injuries, essentially indemnifying vaccines, since 2002. He published his first seminal study that was to indemnify the MMR vaccine from the autism epidemic. He used Denmark data. They never released their data to be reanalyzed. That paper has a fatal flaw that Carl and I found that was published in 2025. It's an arithmetic error. Literally, it's a 9th grade arithmetic error. And it negates their findings. It shows that there is a statistically significant relationship between the MMR uptake and autism in Denmark. They did a follow UP study in 2019 again on the MMR vaccine. They did follow up studies on thimerosal containing vaccines in 2002, 2003, but it's the same playbook every time. You can actually look through the information, you can find the fatal flaws and you can also find an inconsistency between what they say in their abstracts, what they say in the conclusions, from what their actual tables belie that there is a significant relationship. They need to look deeper. And probably the most egregious example of the sleight of hand by Anders of the Statin Serum Institute in Denmark is this latest aluminum paper that came out in 2025.
Glenn (Co-host or Interviewer)
And what you're suggesting, though, a reasonable person would listen to this and say, okay, if that's true, then obviously these papers have been retracted and corrected. Does that ever happen?
Dr. Brian Hooker
No. The latest paper that. I'm so glad you asked. The latest paper actually, Secretary Kennedy wrote an editorial calling for the retraction of that paper and he quoted some of our research, he quoted some other research that basically negated the conclusions of that paper. Now, I've worked with Secretary Kennedy before he became Secretary Kennedy. We had worked together for 10 years. He's the most scientific attorney I've ever met. He was somebody that voraciously devoured science. And, and he would call me, you know, in the advent, what we used to call speed dial. He was on, in my phone, I was in his phone. He would call me with the questions, you know, day or night. And so, you know, I had the hotline, had a special ring and if he had a question, he would ask the questions. But literally he understands the science around these epidemiology studies around better than many of the sciences scientists that I've seen, especially, you know, working for the cdc, working for the Statin Serum Institute, or at least, you know, what they appear to understand in their publications.
Glenn (Co-host or Interviewer)
Right.
Dr. Brian Hooker
So he called for the retraction and it was never retracted. The, the journal chief editor came out and said, and made a statement, no, we are not going to track you retract this paper. Although, you know, myriad scientists were piling on and showing the fatal flaws of this paper.
Glenn (Co-host or Interviewer)
So, so it's a really rare, it's rare for any study to be retracted, right? Because even, even if there's clear evidence, there's just a lean toward just leaving it alone.
Dr. Brian Hooker
If it is supporting the vaccination program, if it's supporting vaccination, it's very, very, very difficult to get a paper retracted. The opposite is true. If you are pointing out vaccine injury, if you're pointing out relationships between adverse events and vaccines. I had my own unfortunate retraction in 2014, a paper on the MMR vaccine that showed that if it was given early to African American males, then their rates of autism were three and a half times higher than those that just waited until three years of age. So, you know, and to endure a retraction like that, you know, for some individuals it's almost a career ender for me. I was working at a small non research university at the time. I was one of the few professors on campus doing research. I got together with the provost of the university and we had a laugh about it, and that was it. So I had an institution that supported me through the retraction, republished the data in a different journal in 2018.
Glenn (Co-host or Interviewer)
Okay, so that's, that's how you addressed it. Then you just republished it, maybe made some minor changes, but the, the conclusion is still the conclusion.
Dr. Brian Hooker
Right, right. And many researchers, you know, in our. In our milieu, Chris Shaw, he's had a paper retracted from the journal Vaccine. He went ahead and published it in a different PubMed index journal. There are so many others that have faced that type of consequence. I was co authors with a paper with Mark and David Guyer. It was retracted and then republished by the same journal in a different version. So the strategy is to get it in print, get it republished, and I try to encourage authors. Mark Skidmore from Michigan State University regarding the COVID shot, was one individual that had his paper retracted and straight away he republished it in a different journal.
Glenn (Co-host or Interviewer)
Got it. Yeah. So basically the retractions go one way usually. And I guess there's no better example than Dr. Andrew Wakefield's paper in the Lancet, which was retracted. And as far as I know, that it's still retracted. It's not like that was ever reissued.
Dr. Brian Hooker
No, it wasn't reissued. And really there was nothing to retract because he never connected directly scientifically the MMR and autism. He just suggested that through parental reports, eight out of the 12 cases in his case series, the parents reported autistic regression after the MMR vaccine. End of story. Never should have been retracted. It was just anecdotal information that was used. Sort of a side note of the entire paper that dealt more with the gastrointestinal issues that we know are in the crosshairs are associated with autism and Autism Spectrum disorder.
Glenn (Co-host or Interviewer)
It makes it even that much more amazing, right, that something would be retracted that didn't really say anything other than we should look a little more closely here. There might be something here.
Dr. Brian Hooker
Exactly, exactly. It was a non event in the paper, but that suggestion that they look into the MMR vaccine to the pharmaceutical industry was a shot across the bow. And so it was dealt with swiftly and severely. And it cost one of my greatest heroes, Dr. Andrew Wakefield, that cost him his career and his livelihood.
Glenn (Co-host or Interviewer)
No, there's been a lot of casualties out there. No bigger one than him in terms of the impact of shining a light on something that needs more exploration and revealing the truths that might be inconvenient. And I guess as people who are listening right now, I think the one thing I wanted to kind of shift to is, if you think about aluminum exposure, to talk a little bit about the timing because again, we can all play better defense as parents prenatally once our child's here. But in terms of potential for harm because of aluminum toxicity, specifically, what has your research found with respect to timing? How important is that?
Dr. Brian Hooker
I'm so glad that you asked that, because when you look at exposure to toxins that cause massive amounts of oxidative stress and damage, damage to the neuroimmunological system like aluminum does the, the timing of the toxicity really will dictate what the disorder is. The timing for neurological development and neurodevelopment that has been implicated in the brains of autistic children is anywhere from the prenatal period through the perinatal period to about anywhere between 18 months and 3 years of age. Okay, so that is the timing of the etiology of autism in the brain. At the same time, in utero, fetuses are exposed to aluminum through the TDAP vaccine that has aluminum in it. They're then exposed on the first day of life to the hepatitis B vaccine and then a whole slew of different vaccinations, many that contain aluminum. Live virus vaccines do not. So the rotavirus doesn't. The MMR vaccine does not contain aluminum. But the dtap, the hepatitis B, the hepatitis A, the haemophilus, influenza biology, the pneumococcal vaccine that is given, all contain aluminum. And these are given at 2 months, 4 months, 6 months. There's another round of them at 12 months and then 15 to 18 months.
Glenn (Co-host or Interviewer)
And the reason for that, by the way, is Right. You can't introduce a live virus and also have a metal like aluminum in there. It would just negate the virus, Correct?
Dr. Brian Hooker
Correct. It would denature the virus. So you don't find in these live virus vaccines, you never found mercury, they couldn't produce them in multi dose vials. And you would never find aluminum because it goes directly to the live virus and it denatures it.
Glenn (Co-host or Interviewer)
So from a timing standpoint, if you're a parent, so I guess let's just look at it overall. If a parent's trying to play better defense, how can they take this knowledge, the insight of your research, what are their takeaways in terms of playing better defense and doing what we all want to do as parents, right, which is, you know, help our child be not exposed to an excessive level of toxins of all kinds. What can parents do?
Dr. Brian Hooker
Well, wherever you are on the vaccine issue, I Ask you to look into this, to even look at our paper. If you have a question on the paper, email me at Dr.brianhooker brian with an I hookermail.com and look at this publication. You know, I think I want parents to read science. I want parents to ingest science and to work with scientists. You know, email me. We will respond. You know, unfortunately, I have helped to respond on that particular email address. So, you know, when I do podcasts, that's, that's the email that I put out to look at this specifically and to also be informed of the levels of aluminum that are going in. When you're making vaccination choices for your child, you want to avoid aluminum exposure. If you have a child on the spectrum, you want to avoid re exposure, especially in the most vulnerable developmental periods, which would be all the way up to three years of age.
Glenn (Co-host or Interviewer)
So from that standpoint, whether you choose to vaccinate or not. Right. That's a question. The timing, whether you follow the schedule or delay the schedule and push things out could be a strategy. And I know, especially after my son experienced his challenges, when my daughter came along, I know my wife Cass and I, we researched the different manufacturers of the vaccines because each different manufacturers could have different levels. And so you might quote, unquote, find something that might be a little bit cleaner, perhaps. So there's things you could do just to be better informed about what's going in. But again, I think the more due diligence you do about what's in here, what's the cost benefit, regardless of what authorities might be suggesting, when you really look at the data and look at the science, that can definitely lead you to make very different conclusions.
Dr. Brian Hooker
Absolutely. If I could add one more thing, invoking my good friend Dr. William Parker, one of the things that you don't want to do with vaccination, if you're choosing to vaccinate your child, especially in that vulnerable developmental window, do not use baby Tylenol if they're running a fever. I mean, and I hate to say that, I mean, it's directly, you know, implicating a product in that. But, Glenn, the more data that I see on that, the more that it really, you know, strikes fear in my heart. This was something that happened to my own son when we, you know, he, he got the haemophilus influenza B, he got the hepatitis B and then the oral polio. No, I'm sorry. Haemophilus influenza B, the dtap, and the oral polio vaccine, all while having active severe infection we came home, he had a fever we couldn't treat, so we rotated baby asp from baby Tylenol. Literally, the first time that we used Tylenol was when he was 15 months old. And that is when he regressed. So that, you know, to me, anecdotal evidence, in addition to the volumes of evidence, 30 different lines of evidence regarding acetaminophen toxicity, especially after a big oxidative stress event like aluminum exposure and vaccines. To me, that's really the one, two punch that I would want all parents to avoid.
Glenn (Co-host or Interviewer)
Yeah, no, I'm glad you brought that up, and I'm sorry to hear that. And I know Dr. Parker's been on before talking about Tylenol. He'll be on again to share his wisdom in a few weeks. And I know, particularly with Tylenol, you know, what he talks about is that it's kind of an equation that if you. If you have a compromised immune system, that coupled with Tylenol seems to be what basically can create harm. Is there anything more like if a parent's wondering, hey, is my child better able to deal with toxic metals like aluminum? Is there any other guidance you would give on what parents might want to consider to see if it might be a good idea for them to play better defense and maybe delay and. And schedule things out? Any thoughts on that?
Dr. Brian Hooker
I really strongly believe in doing some genetic testing and being a good parent observer of how your child is reacting. After one vaccine, if you choose to vaccinate, see how they react. After one vaccine, look and see what's going on. Because there are certain children that, because of genetic mutations, they're called single nucleotide polymorphisms because of those genetic mutations. They are poor excreters of heavy metals. They are poor excreters of Tylenol. They're poor producers of reduced glutathione. Reduced glutathione is tags toxins that cause oxidative stress and allows them to be eliminated from the system. Okay. They are tagged with this little tripeptide called glutathione. It's. It's a small, small molecule, three amino acids, and it has to be in the reduced form. There are kids like my son, that genetically cannot produce that level of reduced glutathione. At the head of that is really the MTHFR mutation. You know, there. There are two mutations. It's methylene tetrahydrofolate reductase is the gene, and there are two specific mutations that will compromise the ability to form methylation for sulfation. That go directly into the recycling of reduced and oxidized glutathione. So certainly if they're positive in one or both of those mutations, then that is a child that's going to be more, more susceptible to that type of injury.
Glenn (Co-host or Interviewer)
Yep, that makes a lot of sense. And yeah, we've talked on the show about functional genomics and how that could give you really good information. And I know personally, for my family, for myself, that's really important information to have. I know I have the double SNP for the hfr. My son has a single. So at least if I would have had that information earlier on. Yeah, we would have made different decisions with respect to those choices that we made. And again, everyone can make their own choice. But I'm a huge fan of true informed decision making where sometimes it takes a little effort to read a research study to look more underneath the surface level recommendations you may be giving or you may be getting. But otherwise, with more information and more awareness and thank you for all the research that you do to provide that. With that information, parents can make better decisions for what's right for their family.
Dr. Brian Hooker
Absolutely. Be a happy detective with your child. Be a happy detective. Make sure that regardless of what the choice you make, that you've done your research that you've looked at. Okay, what am I putting into my child's body? Whether it's food, whether it's air they breathe, whether it's building air, whether it's what's in your soil, what's in your local municipality, Water should be get filtered water or bottled water instead. My son was a metals hyper accumulator and so any type of metal in his environment we found when we did his metals hair test and urine and fecal test. So be a happy detective. Know your child, you know, you spend 247 with them, do the observations, research what you're putting in their bodies.
Glenn (Co-host or Interviewer)
Yep. And the reality is some of our kids just aren't good at excreting metals and dealing with it for a variety of reasons. So knowing that makes all the difference. I know on this show we talk about so many different stressors. You know, with metals being one mold, electromagnetic fields, there's a lot of toxic exposure. And I know CHD does a phenomenal job of helping to educate parents. But if you could bottom line it, Brian, in terms of, yes, all those toxins are worth playing defense on. But why particularly what would you suggest to a parent why they really want to spend more time on aluminum specifically?
Dr. Brian Hooker
Well, when you look at the injection system or the exposure system of aluminum adjuvants. And these are aluminum salt adjuvants. In vaccine, they're a different form of aluminum. They're aluminum sulfate and aluminum phosphate. We which is way different than the metallic aluminum that you would get from drinking a pop from a can. But the injection system is the perfect delivery system. So 100% of that particular component is going to be absorbed in the body. It is not like ingestion or inhalation where there's a mechanism and a route to directly detox it from the body. Okay, so this is 100% absorption of this aluminum that we know is in levels that far eclipse the recommended values. Like I said, the 5 micrograms per day in parental nutrition for preemies, that's the best information I can find for the toxicity of aluminum. And so you look at 250 micrograms, you're eclipsing that by 50 times. You look at 1,000 micrograms, you're Eclipsing that by hundred times. Right.

So the sheer levels and the direct delivery mechanism are reasons why people might want to pause and just again, better understand this. So again, I appreciate what you're putting out there, Brian. Keep I'd ask you what the next research study is, but perhaps if you want to give a teaser, feel free. Otherwise I will definitely have you on as you continue to do the great work that you're doing.
Dr. Brian Hooker
Well, I want to tease two things if I may. We're having a conference called Science Unleashed. It does feature CHD science. It's May 9th if you're in the Phoenix area or if you can get in The Phoenix area May 9. Go to az.childrenshealthdefense.org to get more information for that particular conference. It's going to feature Dr. William Parker, Dr. Chris Shaw, Dr. Clayton Baker talking about geoengineering. I'm going to be talking about autism and vaccines as well as Carl Jablonowski is going to be talking specifically about autism, autism incidents and autism and vaccines. In addition, we have a paper coming out, it should be coming out around May 1 regarding mitochondrial autism and how vaccines exacerbate that phenomenal topic.
Len (Host of Autism Parenting Secrets)
Yeah, I will look forward to that
Glenn (Co-host or Interviewer)
and once that comes out, yeah, I would love for you to come on and bottom line it for our listeners again. So again thank you so much for sharing your voice Brian and for everything that you do.
Dr. Brian Hooker
Thanks so much Lynn.

In this episode, the hosts sit down with Dr. Brian Hooker to dive deep into the underappreciated issue of aluminum exposure, especially via vaccine adjuvants, and its potential link to autism and neurological challenges in children. Drawing on Dr. Hooker’s recent research and decades of experience, the discussion focuses on what aluminum does in the body, why its risks are often overlooked, flaws in vaccine safety research, the importance of timing in exposure, and practical advice for parents aiming to protect their children.
Key episode message:
Take aluminum exposure seriously — especially for young children and those on the autism spectrum.
"They're injecting over 250 to 330 micrograms of aluminum... over 50 times what the limit should be." (00:00, 04:18)
"...these T cells, when they get into the brain... turn on these brain cells called astrocytes. All of that is hastened by aluminum entering into the body." (13:00)
“If it is supporting the vaccination program... it’s very, very, very difficult to get a paper retracted. The opposite is true...” (23:21)
"They did a statistical trick... They did not have a zero aluminum exposure control group." (15:53)
"I want parents to read science. I want parents to ingest science and to work with scientists..." (30:19)
"Do not use baby Tylenol if they're running a fever... after a big oxidative stress event like aluminum exposure and vaccines. To me, that's really the one, two punch..." (32:26)
"There are certain children that, because of genetic mutations... they are poor excreters of heavy metals... poor producers of reduced glutathione." (34:49)
"Be a happy detective with your child... Know your child, you know, you spend 24/7 with them, do the observations, research what you're putting in their bodies." (37:28)
“It is not like ingestion or inhalation, where there’s a mechanism... to directly detox it from the body. This is 100% absorption of this aluminum...” (38:55)
The episode urges listeners—especially parents of children on the spectrum or those expecting—to educate themselves on vaccine ingredients, pay attention to the windows of greatest vulnerability, and become “happy detectives” regarding everything their children are exposed to, with aluminum adjuvants in vaccines singled out as an area needing particular caution and further independent research.
