About Gary Brecka →
Gary Brecka is a self-described human biologist, biohacker, and longevity specialist who spent more than two decades working as a mortality researcher in the life insurance industry, analyzing blood and genetic markers to estimate lifespan. He later shifted his focus to preventive health, co-founding 10X Health System in 2021, a wellness and health-optimization company. In late 2023 he launched The Ultimate Human podcast, where he interviews scientists, athletes, entrepreneurs, and other guests about longevity, biohacking, and performance. His work centers on identifying nutrient deficiencies, genetic methylation patterns, and lifestyle interventions intended to optimize health and extend healthspan.

Use cold exposure as a productive cellular stressor that increases glutathione output.
“Cold exposure and sauna both stress the cell in productive ways

In a protocol Alternative
Take liposomal glutathione daily as the most effective oral form; it survives gut digestion and delivers glutathione to the bloodstream.
“liposomal glutathione is the effective oral form for daily use
TU▶ 9:45Dosage250–1000 mg/day; sweet spot 500 mg/day; on empty stomach 30 min before food, paired with small fat (MCT or coffee with cream)CaveatsStart low to avoid headaches/fatigue/rashes; consult doctor if pregnant, on chemo, immunosuppressants, or with asthmaCertaintyexplicitstrong endorsement -

Gary personally takes Symbiotica's liposomal glutathione every morning, citing clinical absorption data showing ~2.86x higher absorption vs comparators.
“That's why I personally use the Symbiotica glutathione

Avoid Tylenol/acetaminophen — it is one of the fastest depleters of glutathione and a leading cause of acute liver failure.
“Acetaminophen, Tylenol, is one of the fastest known glutathione drains

Alternative
IV glutathione has the highest bioavailability but requires clinic visits, costs $100–$300/session, and effects last only a few days.
