Description
What does it include?

The Glutathione Index Test provides a comprehensive assessment of your body’s most powerful antioxidant — glutathione. Analysed in certified laboratories in Australia and Europe, this advanced at-home dried blood spot test measures both reduced glutathione (GSH) and oxidised glutathione (GSSG) levels to deliver your personalised Glutathione Index.

Glutathione is essential for detoxification, immune defense, and cellular protection against oxidative stress. Found in nearly every cell, it supports liver function, energy production, and healthy aging. Low glutathione levels can lead to fatigue, increased susceptibility to illness, and slower recovery after physical or metabolic stress.

By understanding your Glutathione Index, you gain insight into your oxidative balance — helping you take targeted steps through nutrition, lifestyle, or supplementation to optimise health and longevity.

Collect your sample easily from home using a simple finger-prick, and receive precise, scientifically validated results from our accredited labs in Australia or Europe.
