Sauna & Your Body's Real Detox
Gary Brecka is right that detox is not just sweating, your liver and kidneys do the real work. Where we differ: that means the sauna's value is recovery and circulation, not flushing toxins, so hydrate and keep it sensible.
Trust your liver and kidneys Understand that these organs detoxify continuously; you cannot dramatically 'boost' it with a hack or a sweat session
Getting this right stops you chasing toxin-flushing claims that do not hold up.
Drink water through your session Brecka's ~1 litre during a sauna is reasonable; add electrolytes if you sweat heavily, and rehydrate after
Heavy sweating loses fluid and sodium; hydration is the genuinely important part of his protocol.
Chase recovery, not toxins Treat sauna as cardiovascular and recovery training (see Rhonda Patrick's sauna protocol), not a detox tool
The cardiovascular and recovery benefits are well evidenced; the detox framing is not.
Prefer precursors over plain oral glutathione Plain oral glutathione absorbs poorly; if you want to support it, NAC and glycine (precursors) or liposomal forms are better supported. The before-sauna timing is optional
The supplement Brecka names is the weakest link; precursors are a more evidence-based route.
Limit time and heat Start with 10 to 15 minutes; get out if you feel dizzy, lightheaded or unwell; never sauna dehydrated or after alcohol
Most sauna risk is from heat and dehydration, not from skipping any supplement.
Detoxification is a real, ongoing biological process run by the liver (which chemically transforms toxins) and kidneys (which excrete them in urine), with help from the gut and lungs.

Is this for you
- Sauna users who want the honest version
- Anyone sold on 'sweating out toxins'
- People who want sauna's real recovery benefits
- Anyone deciding if glutathione is worth it
Cautions
- 'Detox' is largely a marketing concept; your body detoxifies itself continuously, and no sweat session, supplement or kit dramatically boosts it. Sweat removes only trace toxins
- Plain oral glutathione is poorly absorbed; if you supplement, precursors (NAC, glycine) or liposomal forms are better supported, and even then the before-sauna ritual is optional, not essential
- Sauna safety matters more than any supplement: avoid it when pregnant, dehydrated, or after alcohol, and check with a doctor if you have heart disease, low blood pressure or are on medication; get out if you feel unwell
- Gary Brecka's wider content includes some disputed claims; this protocol keeps the sound part (liver and kidneys do the work, hydrate) and flags the weaker parts
