Gary Brecka vs Bryan Johnson
Compare Gary Brecka's protocol (Human Biologist & Biohacker) with Bryan Johnson's approach (Entrepreneur & Longevity Pioneer). Brecka emphasizes methylation, gene-based supplementation, and oxygen optimization, while Johnson focuses on data-driven anti-aging and precise nutrition. Both recommend foundational supplements but differ sharply in methodology — Brecka personalizes through genetic testing while Johnson optimizes through biomarker tracking.

What They Agree On
Both Gary Brecka and Bryan Johnson include these 3 products in their protocols — a signal of strong evidence and broad expert consensus.
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
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.

supplements
Where They Differ
These products are unique to one protocol — reflecting each expert's distinct philosophy, research focus, and priorities.

Only in Gary Brecka's Protocol
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.
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.
Folate (Methylfolate 5-MTHF)
Bioactive methylfolate (5-MTHF), the body-ready form of folate critical for DNA synthesis, repair, and methylation. Unlike synthetic folic acid, methylfolate bypasses the MTHFR enzyme conversion step, making it effective for individuals with common MTHFR gene variants. Supports homocysteine metabolism, neural tube development, and red blood cell formation.
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.

Only in Bryan Johnson's Protocol
Extra Virgin Olive Oil
Cold-pressed extra virgin olive oil, a cornerstone of Mediterranean and longevity diets. Rich in polyphenols and oleic acid.
Dark Chocolate (85%+ Cacao)
High-cacao dark chocolate rich in flavanols and antioxidants. Studies link regular consumption to improved cardiovascular health, lower blood pressure, and enhanced cognitive function.
Raw Macadamia Nuts
Raw, unsalted macadamia nuts prized for their high monounsaturated fat content and low omega-6 to omega-3 ratio. A favored fat source in longevity-focused diets for their anti-inflammatory profile.
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.
Organic Blueberry Powder
Freeze-dried organic blueberry powder concentrated in anthocyanins and antioxidants. Supports cerebrovascular health, cognitive function, and cellular protection against oxidative stress.
