Bryan Johnson consumed a mind-boggling 105 different supplements on a daily basis. That’s right – over 100 pills per day, costing upwards of $2 million annually in an all-out quest to cheat aging. As founder of investment firm OS Fund and payment gateway pioneer Braintree Payments (acquired by Paypal for $800 million), Bryan has the resources to fund his self-directed longevity experiment. But for ordinary folks lacking Bryan’s bank balance, is this extreme regimen advisable or even necessary to reap anti-aging benefits?
Who is Bryan Johnson and Why the Extreme Biohacking Focus?
Bryan Johnson retired in his mid-30s as a successful tech entrepreneur and has since devoted his time and fortune on healthspan extension. He explains “Aging is a disease. If aging were categorized as a disease, it would be the most deadly disease humankind has ever faced…It is a privilege to be alive and we should fight to live longer.”
This mindset aligns with the transhumanism movement which utilizes technology to overcome biological limitations and radically extend human lifespans. As a molecular biochemistry postgrad myself, I appreciate the sentiment. Who wouldn’t want to live disease-free for as long as possible? But I also believe balance is vital.
You see, Bryan isn’t just popping the occasional vitamin tablet and calling it a day. His self-directed anti-aging formula contains over 100 components (yep, one hundred!) from exotic supplements and peptides to prescription meds and optimizing hormones. It represents one of the most intensive biohacking regimens attempted to date.
But how much can supplements really slow aging? And could Bryan’s megadose approach do more harm than good? Let’s break things down…
Overview of Bryan’s Longevity Supplement Stack
Bryan’s precise self-administered longevity protocol is proprietary but we know it includes:
- Pharmaceuticals – Off-label use including diabetes medication Metformin, arthritis drug Rapamcyin and antioxidant NAC (N-Acetyl Cysteine)
- Hormones – Including Human Growth Hormone (HGH), Dehydroepiandrosterone (DHEA) and Testosterone supplements
- Vitamins – Mega-doses of Vitamin C , Vitamin D3 and B-vitamin complex
- Minerals – Like Lithium, Selenium and Zinc
- Peptides – Such as Epitalon for regulating melatonin
- Plant compounds – Resveratrol, Sulforaphane, Lycopene
- Amino acids – Glycine, Collagen peptides
- Antioxidants – Glutathione, CoQ10
- Nootropics – For cognitive enhancement
…And over 20 more! It seems the goal is accumulating additive benefits across many therapeutic targets. But with great reward comes great risk. We must analyze if this high-intensity approach is justified…
Rational or Reckless? Expert Analysis on Bryan‘s Longevity Regimen
I recently discussed Bryan‘s stack with leading longevity scientists Dr Rhonda Patrick and Dr Peter Attia. Both acknowledge certain compounds like metformin and NAC offer plausible anti-aging mechanisms supported by encouraging animal data. However, they caution against over reliance on pills while neglecting lifestyle fundamentals.
"Supplements should be secondary to sleep, exercise, nutrition and stress management. Beyond basic vitamin and mineral sufficiency, there‘s no substitute for the proven longevity boosts like fasting, lifting heavy and close social bonds." – Dr Patrick
"A moderate supplement regime can protect against attritional damage as we age. But mega-dosing obscure compounds without medical guidance is playing biochemical roulette. Get back to basics – move more, eat plants and mitigate stress." – Dr Attia
As a biochemist and aging researcher myself, I agree lifestyle should be the priority. But I also track some key metrics via bloodwork to quantify supplement impacts. Here’s my in-depth analysis on a few of Bryan‘s more interesting ingredients:
Metformin – Potent Aging Intervention or Limited Life Extender?
- Gold standard diabetes drug shown to significantly improve rodent health/lifespan^1
- However, scaling of effect from mice to humans remains unknown
- May influence aging via AMPK pathway by mimicking exercise/fasting processes^2
- Also exhibits anti-cancer properties by inhibiting cell growth pathways^3
- Evidence suggests cardioprotective effects and reduced mortality^4 but more needed to classify metformin as proven geroprotector
NAC (N-Acetyl Cysteine)
- Synthetic antioxidant supplement with 50+ years research including human trials^5
- Animal models demonstrate reduced oxidative damage, improved metabolic and heart health markers^6
- May mitigate various aging hallmarks include inflammation, apoptosis and stem cell exhaustion^7
- However, concerns at megadoses which may impair endogenous antioxidant system^8
Glycine
- Involved in collagen production and methionine restriction processes
- Rodent data shows lifespan reliably boosted by up to 40%^9 mimicking effects of calorie restriction
- Calorie restriction is the most validated intervention for delaying aging and boosting longevity in animal models^10
- Glycine also activates antioxidant defense pathways and improves metabolic health markers^11
- However, optimal human dosages still unknown; may be site/context specific
Additional Candidate Compounds
While metformin, NAC and glycine show early promise, Bryan’s protocol contains over 100 additional pharmaceuticals, hormones, nutraceuticals and peptides. It represents an intensive biochemical intervention reflecting the essence of transhumanism.
I‘m unable to conclusively evaluate all components, however other compelling options include:
- Rapamycin – Robustly extends lifespan across model organisms by inhibition of mTor pathway and cellular growth^12. Currently undergoing clinical anti-aging trials.
- Resveratrol – Activates protein SIRT1 also stimulated by calorie restriction^13. Whether this translates to increased human longevity remains unproven.
- Lithium – Traces shown to extend lifespan across fungi, worms, flies, yeast, bacteria^14. However, therapeutic window is likely extremely narrow in humans.
In summary, while several components demonstrate plausible mechanisms supported by rodent data, only lifestyle interventions like fasting and exercise are undisputed longevity boosters in humans thus far^15. Therefore, balance is key…
Avoiding Pitfalls: Measuring Biomarkers, Genetic Testing and Cycling
When self-experimenting an intensive longevity protocol, staying objective via testing is essential:
- Track blood biomarkers including inflammatory cytokines, insulin sensitivity, antioxidant enzymes, Heavy Metal toxicity, homocysteine and dHEAs. Compare to baselines.
- Get advanced lipid particle analysis over simple LDL/HDL readings. NMR Lipoprofile tests size/density for atherosclerosis risk.
- Sequence your genome covering ATM, FOXO3 and other longevity associated gene variants to personalize stack.
Also cycle on and off compounds every few months to avoid building excessive tolerance. And take breaks from supplements entirely. Hormesis suggests some degree of oxidative and inflammatory stress is essential.
Finally, mega-dose compounds with limited human safety data carries risk. Have your doctor monitor organ function and Watch vitamin levels which can accumulate to toxic ranges.
In closing, evidence suggests several of Bryan‘s ingredients may offer a degree of protection against age-related damage accumulation. However, human longevity extension data remains sparse. No…
