Glutathione is a peptide found in plants and animals. It is a powerful antioxidant produced by the liver to protect the body against free radicals, peroxides, and heavy metals. Glutathione also eliminates poisons such as drugs and pollutants from our bodies.

 

Glutathione is essential for the immune system’s proper functioning and is vital for building and repairing tissue. It acts as an important antioxidant, which helps protect your body from damage to cells caused by free radicals.

 

Personally I use GlutathioneMax year round, primarily due to being on TRT and the high levels of systemic stress brought on by my training, high workload etc – I recommend utilising it as a safety mechanism whenever oxidative stress is ramped up.

 

Who it’s for:

 

This one’s for anyone under high physical or mental load – heavy training phases, work stress, travel, or late-night grind sessions. Especially useful during detox, post-holiday, during prep or when stacking with SupportMax™.

 

What it does:

 

Glutathione is your body’s master antioxidant – crucial for liver detox, immune support, and neutralising oxidative stress. Combining fast-acting S-Acetyl and steady-release Setria® forms gives you comprehensive coverage.

 

The choline adds another layer, supporting cellular function, brain health, and recovery. It’s like giving your body its own clean-up crew and maintenance team in one scoop.

 

How I would use it:

 

I’d mix one scoop (5g) first thing in the morning or before bed – on recovery or rest days, you could double up if life’s throwing a lot at you.

 

I’d keep it chilling in the fridge (clumping doesn’t impact potency) and sip it like a calming post-training detox drink. It’s the clean-up round after the main event – ensuring you bounce back fresh and ready for tomorrow.

 

Bonus tip: Take when you get home after a night out with electrolytes to minimise a hangover the next morning! Thank me later!

 

 

The Science:

 

Oral glutathione supplementation increases body antioxidant stores without adverse effects

 

Study: Randomized controlled trial of oral glutathione supplementation on body stores.

 

European Journal of Nutrition (2015)

 

https://pubmed.ncbi.nlm.nih.gov/24791752/

 

In this randomised, double‑blind, placebo-controlled human trial, participants consumed 250-500 mg/day of oral reduced glutathione for 4-6 weeks. The study found a significant increase in systemic glutathione levels (plasma and erythrocytes), demonstrating the efficacy of oral supplementation for raising antioxidant stores – with no reported adverse effects.

 

 

 

Oral glutathione improves insulin sensitivity and oxidative stress markers in type 2 diabetics

 

Study: The effects of 3 weeks of oral glutathione supplementation on whole body insulin sensitivity in obese males with and without type 2 diabetes: a randomized trial.

 

Applied Physiology, Nutrition and Metabolism (2021)

 

https://pubmed.ncbi.nlm.nih.gov/33740389/

 

This RCT administered 1g/day oral glutathione for 3 weeks in obese adult males, both with and without type 2 diabetes. Supplementation significantly improved insulin sensitivity (measured via hyperinsulinemic-euglycemic clamp) without altering oxidative stress markers – supporting both metabolic and safety benefits in at-risk populations.
