What They Agree On
Both Peter Attia and Ben Greenfield include these 5 products in their protocols — a signal of strong evidence and broad expert consensus.
Omega-3 Fish Oil (High EPA)
High-potency omega-3 fish oil supplement with elevated EPA content. Supports cardiovascular health, reduces systemic inflammation, and promotes healthy brain function and mood regulation.
Omega-3 Fish Oil (High EPA)
supplements
Vitamin D3 (5000 IU)
High-potency vitamin D3 supplement providing 5000 IU per serving to support optimal blood levels. Essential for immune function, bone health, and mood regulation. One of the most widely recommended supplements among longevity researchers due to widespread deficiency.
Vitamin D3 (5000 IU)
supplements
Magnesium (Threonate/Glycinate)
Highly bioavailable magnesium in threonate or glycinate form for superior absorption. Supports deep sleep quality, cognitive function, and nervous system relaxation. Magnesium threonate is particularly valued for its ability to cross the blood-brain barrier.
Magnesium (Threonate/Glycinate)
supplements
Creatine Monohydrate
Pure creatine monohydrate, one of the most well-researched supplements in sports science. Supports muscle strength, power output, and emerging research suggests cognitive benefits. Safe for long-term daily use at 3-5 grams per day.
Creatine Monohydrate
supplements
Electrolyte Mix
Balanced electrolyte mix containing sodium, potassium, and magnesium to support hydration and cellular function. Essential for maintaining energy levels, muscle function, and cognitive performance, especially during fasting or exercise. Sugar-free formulas are preferred in longevity protocols.

Only in Ben Greenfield's Protocol
Collagen Peptides
Hydrolyzed collagen peptides that support skin elasticity, joint health, and connective tissue repair. Easily dissolved in hot or cold liquids for convenient daily supplementation.
Ashwagandha (KSM-66)
KSM-66 ashwagandha root extract, the most clinically studied form of this traditional adaptogenic herb. Supports healthy cortisol levels, reduces perceived stress, and may improve sleep quality and exercise recovery. Widely used in longevity protocols for its effects on hormonal balance and resilience to chronic stress.
Cordyceps Mushroom Extract
Concentrated cordyceps militaris mushroom extract standardized for cordycepin and adenosine content. Traditionally used to support endurance, oxygen utilization, and cellular energy production. Modern research suggests benefits for aerobic capacity and mitochondrial function.
Lion's Mane Mushroom Extract
Dual-extracted lion's mane mushroom (Hericium erinaceus) containing both hericenones and erinacines, compounds shown to stimulate nerve growth factor (NGF) production. Supports cognitive function, memory, and neuroplasticity. A staple in nootropic and longevity stacks for its unique neurotrophic properties.
Exogenous Ketones (BHB Salts)
Beta-hydroxybutyrate (BHB) salt supplement that rapidly elevates blood ketone levels without requiring extended fasting or strict carbohydrate restriction. Supports mental clarity, sustained energy, and may enhance endurance performance. Used as a bridging tool for metabolic flexibility in biohacking protocols.
Bovine Colostrum
Grass-fed bovine colostrum rich in immunoglobulins, lactoferrin, and growth factors. Supports gut barrier integrity, immune function, and recovery from intense exercise. Increasingly popular in longevity circles for its ability to reduce intestinal permeability and modulate inflammation.
Essential Amino Acids (EAAs)
Complete essential amino acid formula providing all nine EAAs in research-backed ratios. Supports muscle protein synthesis, recovery, and lean body composition with minimal caloric load. Preferred over BCAAs alone because the full EAA profile is required for complete protein turnover and tissue repair.
Molecular Hydrogen Tablets
Effervescent tablets that dissolve in water to produce molecular hydrogen (H2) gas. Molecular hydrogen acts as a selective antioxidant, neutralizing hydroxyl radicals without disrupting beneficial reactive oxygen species. Emerging research suggests benefits for exercise recovery, inflammation reduction, and mitochondrial health.
Quercetin
Quercetin is a plant flavonoid with potent antioxidant and anti-inflammatory properties. Supports immune function, cardiovascular health, and has been studied as a senolytic agent that helps clear damaged senescent cells. Often combined with vitamin C or bromelain to enhance absorption.
Glutathione (Liposomal)
Liposomal glutathione supplement for enhanced absorption of the body's master antioxidant. Glutathione plays a critical role in detoxification, immune support, and protecting cells from oxidative stress. Liposomal delivery bypasses digestive breakdown for greater bioavailability.
