Ben Greenfield — maximalist performance & longevity stack

The biohacker’s sprawling daily stack — supplements, peptides and experimental longevity compounds. COI: a large share is his own Kion brand plus paid affiliates. Documented by underlying compound, not endorsed; notable for rejecting branded NMN/NR in favor of niacinamide.

Ben Greenfield is a triathlete, personal trainer, nutritionist, author, public speaker, and former bodybuilder known for the practice of biohacking . He has participated in 13 Ironman competitions and over 120 races, becoming a USA Triathlon top-ranked athlete in his age group for a period of time.

Watch-outs (1)

Melatonin ✕ 5-HTP — Commonly combined for sleep with no meaningful direct interaction. There is no direct serotonin-syndrome risk from this pair — the only caution comes from 5-HTP itself, which raises serotonin. Generally fine to combine for sleep. The real caution is 5-HTP with serotonergic medications (SSRIs/SNRIs/MAOIs), not with melatonin — do not stack 5-HTP with those drugs regardless.

Synergies (4)

CoQ10 + Omega-3 — Taking CoQ10 with fats increases absorption by 3-5x
Omega-3 + Curcumin — Synergistic anti-inflammatory effects through complementary mechanisms
Vitamin D3 + Magnesium — Magnesium deficiency impairs vitamin D metabolism and effectiveness
Melatonin + Magnesium — Enhanced sleep onset and quality through different mechanisms
