When it comes to antioxidants, glutathione is king. It’s produced inside your own cells and is responsible for defending your body against oxidative stress, toxins, and inflammation.
Unfortunately, glutathione levels naturally decline with age, chronic stress, illness, or environmental exposures — leaving you more vulnerable to fatigue, infections, and accelerated aging.
🧬 What Does Glutathione Do?
- Neutralizes free radicals and oxidative stress
- Regenerates vitamins C and E after they've been oxidized
- Detoxifies chemicals and heavy metals via liver pathways
- Supports immune function by regulating white blood cell activity
- Reduces chronic inflammation at a cellular level
Low levels of glutathione are associated with:
- Fatigue and poor recovery
- Increased inflammation and oxidative stress
- Autoimmune and neurodegenerative conditions
- Higher susceptibility to infections
🧪 Why Test Your Glutathione Status?
The Glutathione Index Test assesses your redox balance — a key indicator of how well your body copes with stress, inflammation, and detoxification demands.
It’s especially valuable for:
- People with chronic fatigue or long COVID
- Biohackers and longevity-focused individuals
- Athletes needing optimal recovery
- Those with high exposure to toxins, alcohol, or pollution
🔄 How to Increase Glutathione Levels Naturally
- Eat sulfur-rich foods like garlic, onions, broccoli, and kale
- Supplement with NAC (N-acetylcysteine) or liposomal glutathione
- Exercise moderately — overtraining can deplete levels
- Sleep well — glutathione is replenished during rest
- Reduce alcohol and toxic load to support liver function
🎯 Why Testing Matters
You can’t improve what you don’t measure. Many people with inflammation or fatigue don’t realise their antioxidant systems are underperforming. Testing glutathione gives you the data to personalise recovery, supplementation, and lifestyle choices.

🔎 FAQs About Glutathione Testing
What exactly is the Glutathione Index?
It’s a ratio between reduced (GSH) and oxidised (GSSG) glutathione. A higher ratio reflects stronger antioxidant capacity and resilience against stress.
Is it a blood or urine test?
Our test uses a dried blood spot (DBS) sample collected at home and analysed with LC-MS/MS — the gold standard in redox biomarker testing.
Can supplements raise my glutathione levels?
Yes. NAC, liposomal glutathione, and precursors like glycine and selenium can all help. But response varies, so testing helps guide the right approach.
Should athletes test glutathione?
Absolutely. Intense training increases oxidative stress. Testing helps ensure your recovery systems are keeping pace with your physical output.
