In episode #819 of The Tim Ferriss Show, Dr. Rhonda Patrick delivers a masterclass in evidence-based longevity protocols that could fundamentally transform how we approach aging, brain health, and overall wellness. As a biomedical scientist and founder of FoundMyFitness, Dr. Patrick has dedicated her career to translating complex scientific research into actionable strategies that anyone can implement.
This comprehensive guide distills the key insights from their 2.5-hour conversation, covering everything from the surprising cognitive benefits of a common multivitamin to the optimal sauna protocols that can slash dementia risk by an astounding 66%. We’ll explore the specific supplements, brands, and protocols that Dr. Patrick recommends, complete with direct links to help you implement these strategies immediately.
The Multivitamin Revolution: Centrum Silver’s Surprising Cognitive Benefits
One of the most surprising revelations from the episode involves research on Centrum Silver, a common multivitamin that most people dismiss as ineffective. Dr. Patrick explains that recent randomized controlled trials have shown remarkable cognitive benefits from this specific formulation.
The research followed older adults taking Centrum Silver for two years and found that participants experienced improved cognition on multiple tests, effectively reducing global cognitive aging by approximately two years. Even more impressive, the supplement reduced episodic memory aging by nearly five years (4.8 years to be exact).
These findings challenge the conventional wisdom that multivitamins are unnecessary for most people. Dr. Patrick emphasizes that as we age, our ability to absorb and utilize nutrients decreases significantly, making supplementation increasingly important. The specific formulation of Centrum Silver, designed for adults over 50, appears to address these age-related nutritional gaps effectively.
The cognitive benefits likely stem from the combination of B-vitamins, antioxidants, and minerals that support brain function and protect against oxidative stress. This research provides compelling evidence that a well-formulated multivitamin can serve as a foundation for healthy aging, particularly for individuals who may not be getting optimal nutrition from their diet alone.
Vitamin D: The Longevity Hormone Most People Are Deficient In
Dr. Patrick dedicates significant time to discussing vitamin D, which she considers one of the most critical nutrients for longevity and disease prevention. The statistics she shares are sobering: a 70-year-old produces about four times less vitamin D than their 20-year-old self, making deficiency almost inevitable without supplementation.
The optimal blood level of vitamin D, according to Dr. Patrick’s analysis of the research, is between 40-60 ng/mL. Most people require 5,000 IU daily to achieve and maintain these levels, though individual needs can vary significantly. The Nature Made Extra Strength Vitamin D3 5000 IU provides an excellent starting point for most individuals.
However, Dr. Patrick reveals a critical factor that many people overlook: magnesium deficiency can prevent vitamin D from working effectively. She notes that 50% of the US population has insufficient magnesium levels, which is required for the enzymes that convert vitamin D into its active form. This explains why some people remain vitamin D deficient despite taking supplements.
For those seeking the highest bioavailability, Dr. Patrick mentions the Pure Encapsulations Vitamin D3 VESIsorb formulation, which uses advanced delivery technology to enhance absorption. While more expensive than standard vitamin D3, this formulation may be particularly beneficial for individuals with absorption issues or those who have struggled to raise their vitamin D levels with conventional supplements.
Omega-3 Fatty Acids: Brain Protection for the APOE4 Generation
The discussion of omega-3 fatty acids takes on particular urgency when Dr. Patrick explains their critical role in brain health, especially for individuals carrying the APOE4 genetic variant that significantly increases Alzheimer’s risk. Her recommendations go beyond simple fish oil supplementation to address the specific needs of different genetic profiles.
For most individuals, Dr. Patrick recommends approximately 2 grams of combined EPA and DHA daily. However, for APOE4 carriers, she emphasizes the importance of the phospholipid form of omega-3s, which can better cross the blood-brain barrier. This form is naturally found in salmon roe and krill oil, or can be created by the body when taking higher doses of regular fish oil.
The Nordic Naturals Ultimate Omega represents one of the highest-quality fish oil supplements available, providing 1,280 mg of omega-3s per serving in a highly purified form. Dr. Patrick specifically mentions this brand for its quality and third-party testing, which ensures purity and potency.
For those interested in the most bioavailable forms, sardines and salmon roe provide omega-3s in their natural phospholipid form. However, for consistent daily intake, high-quality supplements remain the most practical option for most people.
The Creatine Cognitive Connection: Beyond Muscle Building
While most people associate creatine with athletic performance, Dr. Patrick reveals its powerful cognitive benefits that extend far beyond the gym. She explains that creatine serves as a rapid energy source for the brain, particularly during periods of high demand or sleep deprivation.
The standard dose for muscle benefits is 5 grams daily, which saturates muscle creatine stores. However, for cognitive enhancement, Dr. Patrick suggests higher doses of 10-20 grams daily, divided throughout the day to minimize potential digestive discomfort. Research shows that creatine supplementation can significantly improve cognitive performance after sleep deprivation, making it particularly valuable for busy professionals and parents.
Momentous Creatine Monohydrate is Dr. Patrick’s recommended brand, which Tim Ferriss also uses. This NSF Certified for Sport product ensures purity and potency, with every batch tested for contaminants and banned substances. The Creapure source represents the gold standard in creatine quality.
The cognitive benefits of creatine appear to be particularly pronounced in vegetarians and vegans, who typically have lower baseline creatine levels. However, even omnivores can experience significant improvements in mental clarity, focus, and cognitive endurance with consistent supplementation.
Sulforaphane: The Detoxification Powerhouse from Broccoli Sprouts
Dr. Patrick’s discussion of sulforaphane reveals one of nature’s most powerful detoxification compounds, found in highest concentrations in broccoli sprouts. This compound activates the NRF2 pathway, which controls the body’s antioxidant response and helps eliminate environmental toxins like benzene and BPA.
The most potent dietary source is fresh broccoli sprouts, which contain 10-100 times more sulforaphane than mature broccoli. Growing your own sprouts ensures maximum potency and freshness. An Organic Broccoli Sprout Growing Kit provides everything needed to produce fresh sprouts at home in just 5 days.
For those who prefer supplementation, Dr. Patrick specifically mentions Avmacol as the brand she gives to her mother. This supplement provides standardized sulforaphane content and includes the myrosinase enzyme necessary for sulforaphane production.
Dr. Patrick recommends taking sulforaphane on an empty stomach for maximum absorption, unless it causes gastrointestinal distress. The detoxification benefits are particularly important in our modern environment, where we’re constantly exposed to pollutants and chemicals that can accumulate in our bodies over time.
Curcumin: Nature’s Anti-Inflammatory Alternative
The conversation turns to curcumin as Dr. Patrick shares her personal use of this powerful anti-inflammatory compound as an alternative to NSAIDs for headaches and delayed onset muscle soreness. The key to curcumin’s effectiveness lies in choosing the right formulation for optimal bioavailability.
Dr. Patrick specifically recommends the Meriva formulation, which uses phytosomal technology to dramatically improve absorption. Thorne Curcumin Phytosome (Meriva) provides 1000mg of this highly bioavailable form, with Dr. Patrick suggesting a dose of four 500mg capsules (2 grams total) for therapeutic effects.
The anti-inflammatory benefits of curcumin extend beyond acute pain relief to include potential protection against chronic diseases associated with inflammation. Regular use may help support joint health, cardiovascular function, and cognitive performance through its powerful anti-inflammatory mechanisms.
Unlike NSAIDs, which can have significant side effects with long-term use, curcumin appears to be safe for extended periods when used appropriately. This makes it an attractive option for individuals dealing with chronic inflammatory conditions or those seeking natural alternatives to pharmaceutical interventions.
The Sauna Protocol That Slashes Dementia Risk by 66%
Perhaps one of the most compelling protocols discussed involves sauna use for longevity and brain health. Dr. Patrick cites research showing that individuals who use saunas 4-7 times weekly have a 65-66% lower risk of developing dementia and Alzheimer’s disease compared to those who use saunas once weekly or less.
The optimal protocol involves 20 minutes at 174°F (79°C), which activates heat shock proteins that help repair misfolded proteins and protect against cellular damage. Importantly, Dr. Patrick notes that hotter is not necessarily better, with temperatures above 190°F (88°C) potentially being less beneficial.
For those without access to a traditional sauna, hot baths can provide similar cardiovascular benefits. The protocol involves 20 minutes in 104°F (40°C) water, which has been linked to a 28% reduction in cardiovascular disease risk when practiced daily.
The mechanisms behind these benefits involve the activation of heat shock proteins, improved cardiovascular function, and enhanced protein quality control systems. These adaptations appear to provide significant protection against age-related diseases and may contribute to increased longevity.
VO2 Max: The Ultimate Longevity Predictor
Dr. Patrick emphasizes VO2 max as potentially the single best predictor of longevity, with research showing that individuals with higher cardiorespiratory fitness have a five-year increased life expectancy compared to those with low fitness levels. Even more striking, having low cardiorespiratory fitness carries mortality risks comparable to or worse than known diseases like type 2 diabetes or smoking.
The good news is that even modest improvements in VO2 max can provide significant benefits. Moving from low to low-normal cardiorespiratory fitness is associated with a two-year increase in life expectancy, making this one of the most impactful interventions for longevity.
Dr. Patrick discusses the Norwegian 4×4 protocol as one of the most effective methods for improving VO2 max. This involves four minutes at 85-95% maximum heart rate followed by three minutes of active recovery, repeated four times. This protocol has been shown to produce significant improvements in cardiorespiratory fitness in relatively short periods.
Zone 2 training, performed at a conversational pace below the lactate threshold, provides complementary benefits by improving fat oxidation and building aerobic base. The combination of high-intensity interval training and steady-state aerobic exercise appears to provide optimal benefits for cardiovascular health and longevity.
The Fasting Protocols That Activate Cellular Repair
Dr. Patrick provides detailed insights into various fasting protocols, from intermittent fasting to extended water fasts. She explains that intermittent fasting, particularly the 16:8 protocol (16 hours fasting, 8 hours eating), naturally reduces caloric intake by approximately 200 calories per day while activating beneficial cellular processes.
The 16:8 protocol involves restricting eating to an 8-hour window, such as noon to 8 PM, while fasting for the remaining 16 hours. This approach activates autophagy, the body’s cellular cleanup process that removes damaged proteins and organelles. Dr. Patrick emphasizes that being in a catabolic state is necessary for repair processes to occur effectively.
For more advanced practitioners, extended fasting of 7-30 days can provide profound benefits but requires medical supervision. These longer fasts can trigger more extensive autophagy and provide significant anti-inflammatory effects. However, Dr. Patrick stresses the importance of proper refeeding protocols to maximize benefits and minimize risks.
The Fasting-Mimicking Diet (FMD) offers a middle ground, providing many of the benefits of extended fasting while allowing some food intake. This 5-day protocol involves consuming a low-calorie, low-protein, plant-based diet that tricks the body into a fasting state while maintaining some nutritional support.
Water Filtration: Protecting Against Microplastic Contamination
A concerning topic that Dr. Patrick addresses is the pervasive presence of microplastics and nanoplastics in our food and water supply. These particles can cross biological barriers, including the blood-brain barrier, and have been found in cardiovascular disease patients, suggesting potential health impacts.
The most effective protection involves using reverse osmosis filtration systems, which can remove particles as small as 0.001 micrometers. The Big Berkey Water Filter System provides effective filtration in the 24-26 nanometer range, offering significant protection against microplastic contamination.
Dr. Patrick also recommends avoiding plastic tea bags, which can release billions of microplastic particles when steeped in hot water. Using loose-leaf tea with stainless steel, glass, or food-grade silicone infusers provides a plastic-free alternative for tea consumption.
Simple changes like choosing glass over plastic bottles for beverages, especially hot drinks, can significantly reduce microplastic exposure. Dr. Patrick specifically mentions Blue Bottle Coffee for their use of plastic-free, sugarcane-lined cups that don’t leach microplastics into hot beverages.
The Magnesium Connection: The Missing Link in Supplementation
Dr. Patrick reveals that magnesium deficiency affects approximately 50% of the US population, making it a critical factor in overall health and the effectiveness of other supplements. Magnesium is required for over 300 enzymatic reactions, including those that convert vitamin D into its active form.
The various forms of magnesium offer different benefits: magnesium glycinate for general supplementation and sleep support, magnesium citrate for digestive health, magnesium malate for energy production, and magnesium threonate for potential brain benefits due to its ability to cross the blood-brain barrier.
A typical supplemental dose ranges from 300-450mg daily, though individual needs can vary based on diet, stress levels, and other factors. Dr. Patrick emphasizes that addressing magnesium deficiency can improve the effectiveness of other supplements, particularly vitamin D, and support overall metabolic function.
Alcohol and Cancer Risk: The Uncomfortable Truth
Dr. Patrick addresses the controversial topic of alcohol consumption and health, revealing uncomfortable truths about cancer risk that challenge popular beliefs about “moderate” drinking. She explains that a woman’s lifetime risk of breast cancer is one in eight, but moderate alcohol consumption can increase this risk to one in six.
The research on alcohol’s health effects has been confounded by the “sick quitter hypothesis,” where people who quit drinking due to illness are miscategorized as healthy non-drinkers in studies. This has led to overestimation of alcohol’s benefits and underestimation of its risks.
Dr. Patrick’s analysis suggests that the cardiovascular benefits often attributed to moderate alcohol consumption may be largely mythical when proper controls are applied. The cancer risks, however, appear to be real and dose-dependent, with even moderate consumption increasing risk for several types of cancer.
Emerging Therapies: Psilocybin and Ketamine for Brain Health
The conversation touches on emerging therapeutic compounds, including psilocybin and ketamine, for their potential benefits in treating depression and supporting brain health. Dr. Patrick explains that psilocybin offers potent anti-inflammatory effects that can be achieved at sub-perceptual doses, potentially providing therapeutic benefits without psychoactive effects.
Unlike ketamine, which can be addictive and may have negative cognitive effects with repeated use, psilocybin appears to be non-addictive and may actually promote neuroplasticity and reduce neuroinflammation. Research suggests it may have applications in treating age-related cognitive decline and neurodegenerative diseases.
However, Dr. Patrick emphasizes that these compounds should only be used under proper medical supervision and that more research is needed to fully understand their therapeutic potential and optimal protocols.
