Transcribe →Aging is best explained by declining mitochondrial function over time.
Dec 900:03:16Tap to summarizeAging is best explained by declining mitochondrial function over time. This answers its own "why." Mitochondria produce the energy needed for repair so if any of it gets lost it sets up a vicious cycle. And some *always* gets lost. But how much is under your control. From Joe Rogan Experience JRE 2420. https://www.youtube.com/watch?v=QBn54YNnKD0 It's a vicious cycle initiated by the second law of thermodynamics which requires a constant input of energy to prevent the collapse of order. Hence, there will always be slippage, but how much slippage depends on genetics, environment, and behavior, and all slippage leads to loss of mitochondrial repair, which itself directly causes the loss of repair capacity as it weakens the defense against the imperative of the second law of thermodynamics.

Mitochondria: Why They Control Everything in Human Health
Dec 401:42:57Tap to summarizeMitochondria govern everything. Watch this with the slides here: https://www.youtube.com/watch?v=mED1_L3wZbc Mitochondria convert your food to usable energy in the form of ATP, which is used to produce, maintain, repair, distribute, and organize everything in your body. Abundant health right now, and preserving your health throughout the lifespan toward your longevity, all depends on your mitochondria. In fact the best explanation for aging is that its a vicious cycle of declining mitochondrial function. We should always be thinking of mitochondria first. SSRIs, acne treatments, and statins are given as examples. Targeting mitochondria without proper testing has its own set of problems. This video covers the top things we should all be doing for our mitochondria and how to figure out our own mitochondria's unique needs. This is not medical advice and is for educational purposes only. 1:20 Mitochondria govern everything because they convert food into usable energy 7:25 Mitochondrial dysfunction drives aging 10:43 Depression starts with your mitochondria 17:26 The problem with SSRIs 21:59 Acne should start with vitamin A, zinc, B5, and mitochondrial function 28:00 Cardiovascular disease starts with mitochondrial dysfunction 40:26 Statins are mitochondrial toxins 54:00 Targeting mitochondria without testing can be dangerous: three examples. 59:45 CoQ10: no one dose and no one supplement for everyone. 1:04:30 Methylene blue can make your mitochondria worse if you don't need it. 1:07:48 The power of mitochondrial testing: three examples 1:15:14 Mitochondrial biology 1:17:32 Your mitochondria are pointless if you don't have creatine 1:18:20 What Mitome is testing 1:20:42 What Mitome reports look like 1:21:57 Energetic bottlenecks are like traffic jams 1:25:01 Organic acid testing of mitochondrial function 1:26:53 Other mitochondrial tests 1:27:44 Five things everyone should do for their mitochondria right now. 1:40:48 We all have unique mitochondrial needs Do You Have Hidden Mitochondrial Dysfunction? Mitochondrial dysfunction is one of the earliest signs of aging and chronic disease—and most people don't know they have it.

SSRI Withdrawal Is Mitochondrial Dysfunction
Nov 2301:29:04Tap to summarizeChris Masterjohn, PhD, Founder and Scientific Director of mito.me, explains why SSRI withdrawal is mitochondrial dysfunction and what to do about it. This is not medical advice, diagnosis, or treatment. 29 million Americans and about 5-10% of the world's population are on SSRIs, which have become the first-line treatment of depression. These can cause sexual dysfunction and emotional blunting in up to half of people, an unclear incidence of sleep disruption, and a rare risk of suicidality, self-harm, and new-onset psychosis. On the other hand, 20-50% of people who go off experience SSRI discontinuation syndrome. This can involve irritability, anxiety, mood problems, crying, dread, suicidal ideation, insomnia, nightmares, excessive dreaming, lethargy, fatigue, headache, tremor, sweating, anorexia, flu-like symptoms, nausea, vomiting, diarrhea, pain, numbness, tingling, feeling like something is crawling on the skin, electric shocks running through the brain or body, rushing noises, visual traces (seeing something persist when it is no longer there, or seeing moving objects leaving illusory streaks of light behind them, etc), dizziness, light-headedness, "brain zaps," vertigo, confusion, difficulty concentrating, amnesia, genital hypersensitivity, and premature ejaculation. A closely related problem is post-SSRI sexual dysfunction (PSSD), which can cause total inability to feel the penis for males or for females the genitals and nipples, loss of sexual pleasure, weak orgasms, decreased libido, erectile dysfunction, and premature ejaculation. PSSD is often associated with general anhedonia, apathy, and poor mood. In this video, Masterjohn maintains that the reason there are no good solutions to these problems is because we have completely misunderstood the role of serotonin and SSRIs. Serotonin's role is to help mitochondria adapt to changing demands for oxygen-based energy production. SSRIs enhance some of the mechanisms, and interfere with others. They enter the cell and stimulate independent mechanisms of mitochondrial stress adaptation, but in doing so they turn a cyclical and rhythmic pathway into a constantly stimulated one, creating mitochondrial dependence and making mitochondria vulnerable to new-onset dysfunction upon withdrawal. Once they make it to the mitochondria itself, the SSRIs act as mitochondrial toxins.

Transcribe →How Lactate Alkalinizes Your Muscles
Sep 6, 202401:34:50Tap to summarizeFor a long time, most people believed that when we exercise, our muscles make lactic acid, this acidifies the muscles, and the acidity contributes to contractile failure, fatigue, and delayed-onset muscle soreness. Some people still believe this. You may have heard the argument against it from well-known figures like Andy Galpin, or, if you're deep into the science, you may have read the work of George Brooks. In this lesson, we are going to cover the biochemistry of lactate production. We will see that we never make lactic acid, ever. We make lactate. Making lactate is fundamentally alkalinizing. We will take a look at the presentation of glycolysis in the Berg and Lehninger biochemistry textbooks to see that, on the one hand, they give us everything we need to know to understand that the human body never makes lactic acid, but, on the other hand, they really do not equip us well to understand where acidity does comes from during exercise. This is because they do not consider acid-base balance important enough to completely present the proton balances of the chemical reactions. Finally, we will cover what does cause muscular fatigue, take a look at the research on lactate supplements, and come to some conclusions about the best way to manage acidity during exercise to maximize performance. This is part of a larger course on the biochemistry of how we derive energy from food and use it to fuel our wellness, performance, and longevity.

Transcribe →D-Lactate: Groundbreaking Research No One Is Talking About
Jul 31, 202401:30:24Tap to summarizeD-lactate is commonly stated to be exclusively a microbial metabolite. This is found in assumptions within the medical literature for decades even when it was long-known to be false. While D-lactate is indeed made by bacteria, D-lactate is also inarguably and irrefutably produced by human enzymes. In this podcast, moreover, I will argue the following: Microbial contribution to D-lactate in humans under normal circumstances is negligible. I coin the term "the D-lactate shuttle" to describe a role for D-lactate that should eventually make its way into biochemistry textbooks alongside the malate-aspartate shuttle and the glycerol phosphate shuttle. The D-lactate shuttle operates alongside these other shuttles to balance the priorities of conserving cytosolic NAD+, reducing cytosolic acidity, bypassing complex I, or generating ATP. It is uniquely useful as a shuttle when there is an absolute deficit of niacin or NAD(H). D-lactate is an important contributor to gluconeogenesis that could account for up to 11% of it and rival an individual amino acid. While D-lactate concentrations in human plasma are infinitesimal, when the downstream metabolism of D-lactate and L-lactate are blocked by genetic disorders, the concentrations of the two forms are similar in plasma. This contrasts wildly with the common claim that flux through D-lactate is "minuscule." Most likely D-lactate is produced in considerable quantities in liver and kidney but is rarely secreted into plasma because doing so would risk neurotoxicity. D-lactate should be taken seriously for its potential role in Parkinson's and in neurological problems generally, for its role in diabetes, and for its extremely underappreciated roles in glycolysis, gluconeogenesis, and the respiratory chain. Oxalate powerfully impairs D-lactate clearance, so D-lactate should be investigated as a potential link between oxalate and autism, and oxalate-lowering strategies should be seen as a way to improve D-lactate clearance and reduce its potential role in diabetes and neurological disorders.
