Episode 1267: Rhonda Patrick | Protecting Your Brain and Body from Modern Life
Date: January 6, 2026
Guest: Dr. Rhonda Patrick (FoundMyFitness)

Main Theme

This episode centers on actionable strategies to protect the brain and body from “modern life” threats, including microplastics, screen time, micronutrient deficiencies, and misleading health trends. Dr. Rhonda Patrick, a scientist known for distilling biochemistry into practical advice, joins Jordan Harbinger to separate science from wellness hype, offer evidence-based health insights, and share practical steps for long-term well-being.

Key Discussion Points & Insights

Screen Time, Technology, and Children's Mental Health

• Screen Addiction & Hyperstimulation

  • Kids are drawn to screens for their hyper-stimulating, dopamine-driven feedback, which can hinder their enjoyment of real-life activities like play and learning.
  • Social media’s comparison culture disproportionately harms girls, increasing risk for depression and eating disorders.
    • “Screens and phones are the new smoking.” — Dr. Patrick, [14:38]

• Family & Community Strategies

  • Dr. Patrick suggests collaborating with parents to delay smartphone exposure and favor traditional landlines or “dumb” phones for communication among kids ([06:28]).
  • Devices like Tin Can allow kids to call only approved contacts—minimizing social media risk.

• YouTube Kids & Content Monitoring

  • Algorithms often serve undesirable or non-educational videos, and harmful content can slip through. Effective parental control is difficult.
    • “I'm fighting a war against YouTube Kids...where they don't even talk, they're just doing action things.” — Jordan, [09:49]

• New Health Risks Associated with Screen Time

  • Research links early high screen time (ages 2–3) to later sensory processing issues and mental health challenges ([13:00]).
  • Dr. Patrick compares screen hyperstimulation to hyper-palatable processed foods—kids often prefer both over healthier alternatives.

Microplastics: What We Know & What Matters

• Prevalence and Impact

  • Microplastics are everywhere: water, air, food, and even products like gum and canned drinks.
  • Microplastics (and even smaller nanoplastics) are absorbed into the body and detected in organs including the brain, placenta, and testes.
    • “There have been a variety of studies now that have found microplastics in everything from placenta, testes, kidneys, heart, brain.” — Dr. Patrick, [21:01]
  • Dogs and humans alike are universally exposed.

• Water as a Major Source

  • Tap and bottled water contain significant microplastic loads.
  • Reverse osmosis filters are most effective; even carbon filters are helpful ([20:07]).
    • “Water, tap water, is a major source of the microplastics that we ingest...the most effective thing you can do is get a filter, drink filtered water.” — Dr. Patrick, [20:07]

• Health Consequences

  • Animal studies suggest microplastics cause neuroinflammation, correlated with Alzheimer’s in humans.
    • “Microplastics have been shown to cause inflammation...you end up getting this vicious cycle of low grade inflammation in the brain which is known to cause dementia and Alzheimer's.” — Dr. Patrick, [28:39]
  • Small nanoplastics are especially risky for absorption and reaching critical organs.

• Chemicals in Plastics

  • Plastics leach endocrine disruptors (e.g., BPA, BPS) linked to hormonal, developmental, and cancer risks.
  • While it’s nearly impossible to avoid all exposures, practical reductions matter.

• Practical Steps for Reduction

  • Reverse osmosis or carbon water filters.
  • HEPA filters for home air.
  • Avoid hot drinks in paper/plastic-lined cups.
  • Switch from tea bags to loose-leaf tea ([38:04]).
  • Use glass or stainless containers (though be aware of plastic linings, such as in cans).
  • Opt for “plastic-free” gum.
  • Increase dietary soluble fiber to prevent microplastic absorption ([22:43]): Fruits, vegetable skins, inulin supplements can bind and eliminate microplastics via stool.

• “Plastic-Free” vs. “BPA-Free” Misconceptions

  • BPA-free may just mean substituted with BPS, which has similar health risks ([42:25]).
  • Most chewing gum is plastic-based unless specifically labeled “plastic-free”.

Micronutrients, Multivitamins & Brain Aging

• Shifting Science on Multivitamins

  • Recent large RCTs (“COSMOS studies”) show that daily multivitamin use in older adults delays brain aging by about two years, improves cognition, and slows episodic memory decline ([47:09]).
    • “What was found was that individuals given the multivitamin...delayed brain aging by 2.1 years compared to the placebo group.” — Dr. Patrick, [47:29]
    • Expensive urine narrative is outdated.

• Micronutrient Deficiency is Widespread

  • Significant proportions of the population lack magnesium, calcium, vitamin A, and vitamin C.
  • Even with good diets, soil depletion and food sourcing make it hard to cover all needs.

• Supplementation Recommendations

  • Centrum Silver (used in trials) is a broadly available but basic option.
  • Dr. Patrick prefers brands like Pure Encapsulations and Thorne, which offer higher bioavailability and testing for contaminants ([51:23]).
  • Micronutrients that usually require additional supplementation:
    • Magnesium: Most people are deficient; citrate, malate, glycinate, or threonate forms are recommended ([54:52]).
    • CoQ10: Especially for those on statin meds; look for ubiquinol for better absorption ([57:09]).

Exercise for Brain & Longevity

• Vigorous Exercise Critical for Healthspan

  • Vigorous activity (HIIT or “exercise snacks”—short, intense bursts) is vastly more effective for lowering mortality than moderate activity ([63:09], [66:50]):
    • 1 min of vigorous exercise = 4 mins of moderate for the same cardiovascular benefit.
    • Any “snack” that raises heart rate (e.g., sprinting stairs) counts.
    • “Vigorous exercise is definitely the king when it comes to reducing cardiovascular mortality, when it comes to all cause mortality, and slightly even more with cancer related mortality as well.” — Dr. Patrick, [67:10]

• Cognitive Benefits

  • Brief vigorous exercise immediately improves reaction and processing speed, and over time, increases hippocampal brain mass (the memory center) in older adults ([70:59]).
    • “Those older adults that were in the exercise group, not only did they not lose the 2% hippocampal region, they gained 1 to 2%...they were increasing the growth of new neurons.” — Dr. Patrick, [71:01]
  • Exercise stimulates BDNF (brain derived neurotrophic factor), key for neuroplasticity and mood.

Creatine: Not Just for Muscles

• Brain Benefits of Creatine

  • Recent research supports 10g/day (not the standard 5g) for brain saturation and benefit ([75:00]).
    • Helps during stress (cognitive or sleep deprivation).
    • Dr. Patrick takes 10g daily for cognitive stamina and swears by higher doses as a jetlag fix.
    • “If I take 10 grams a day, I don't get afternoon sleepiness at all.” — Dr. Patrick, [77:34]

• Supplementation Tips

  • Stick with creatine monohydrate (not gummies—most have zero real creatine, [79:34]).
  • Look for NSF-certified brands (Dr. Patrick uses Thorne for purity).
  • Powder is best, but capsules work if powder taste/texture is intolerable (high daily dose may require many capsules).

• Creatine Also Helps Free Up Methyl Donors, critical for gene regulation/epigenetics.

Notable Quotes & Memorable Moments

• “Screens and phones are the new smoking.” — Dr. Rhonda Patrick, [14:38]
• “Once it gets into your circulation, that’s the point of no return... they go to organs, they accumulate in organs.” — Dr. Patrick, [20:57]
• “I didn’t realize water was...the huge vector.” — Jordan, [29:41]
• “It is almost safer to eat a credit card than to ingest the equivalent in nanoplastics.” — Paraphrasing Dr. Patrick, [32:21]
• “If you see ‘BPA Free,’ it doesn’t mean it’s safe.” — Dr. Patrick, [42:25]
• On multivitamins: “Who doesn’t want to delay global brain aging by two years and episodic memory aging by five?” — Dr. Patrick, [50:08]
• “Vigorous intensity exercise is definitely the king when it comes to reducing cardiovascular mortality.” — Dr. Patrick, [67:10]
• “If I take 10 grams of creatine a day, I don’t get afternoon sleepiness at all.” — Dr. Patrick, [77:34]
