Mitochondria produce toxic byproducts while generating cellular energy, creating a fundamental challenge for cell survival. Glutathione acts as a specialised cleanup crew inside these cellular power plants, neutralising reactive oxygen species before they can damage essential structures.
Glutathione serves as the eye’s primary antioxidant defence system, protecting against the oxidative damage that light exposure inevitably creates in retinal and lens tissues. Research shows that glutathione levels in eyes decline dramatically with age, dropping to less than 15% of youthful levels by age 70.
Elite athletes can lose 40% of their glutathione levels during intense exercise, affecting both performance and recovery. This master antioxidant protects cells from oxidative damage but gets depleted when your body needs it most.
N-acetyl cysteine provides the rate-limiting ingredient cells need to manufacture glutathione, their primary antioxidant defence system. Unlike glutathione supplements, N-acetyl cysteine survives digestion and delivers cysteine directly to cells where it’s converted into the master antioxidant within hours.
Your liver processes 1.4 litres of blood every minute, relying on glutathione as both shield and sword against toxins. This tripeptide molecule neutralises free radicals and tags harmful compounds for elimination through Phase II detoxification pathways.
Glutathione S-transferase enzymes work like molecular bouncers, identifying harmful chemicals and safely escorting them out of cells before damage occurs. These specialised proteins handle everything from environmental toxins to metabolic waste products.
Glutathione is the most abundant antioxidant your body produces internally. It is present in virtually every cell, with particularly high concentrations in the liver, lungs, kidneys and eyes. But this critical molecule does not maintain its levels indefinitely. As you age, glutathione production declines steadily, and the consequences ripple across every system in your body. … Read more
Your body does not just produce glutathione. It recycles it. This recycling system is one of the most elegant features of cellular biochemistry, allowing each glutathione molecule to neutralise multiple reactive species before being broken down. Understanding how this system works explains why glutathione is so effective and why maintaining it matters so much. How … Read more
If glutathione is the master antioxidant, then understanding how your body actually makes it is essential knowledge. The synthesis pathway reveals why oral glutathione supplements are largely ineffective, why certain nutrients and lifestyle factors matter so much and why the NRF2 pathway sits at the centre of your body’s antioxidant defence strategy. The Two Step … Read more
In 1888, a French chemist named J. de Rey-Pailhade noticed that a substance in yeast cells could react with elemental sulphur. He named it philothion, from the Greek for sulphur-loving, and published a short paper describing its properties. The compound did not receive a proper chemical characterisation for another forty years. When it did, the … Read more
