Glutathione is often called the “master antioxidant” — and for good reason. It’s one of the most critical molecules your body produces to defend against oxidative stress, inflammation, and cellular damage. Unlike most antioxidants, your body synthesises glutathione internally — but only if it has the right building blocks and isn’t under too much strain.
🔬 What Is Glutathione?
Glutathione is a small tripeptide composed of three amino acids: cysteine, glycine, and glutamate. It’s present in nearly every cell in your body, where it plays a pivotal role in:
- Neutralising free radicals
- Detoxifying heavy metals and chemicals
- Recycling other antioxidants like vitamins C and E
- Regulating immune and inflammatory responses
- Maintaining redox balance in your cells
🛡️ Why Glutathione Matters
- Immunity: Glutathione supports both innate and adaptive immune systems and is vital for fighting infections and regulating inflammation.
- Detoxification: It plays a key role in liver detox, helping to eliminate environmental toxins, heavy metals, and even medications.
- Anti-aging: Low levels of glutathione are associated with chronic fatigue, slower recovery, and increased risk of degenerative diseases.
📉 What Causes Glutathione Depletion?
Even though your body can produce glutathione, several factors can deplete it:
- Chronic stress and poor sleep
- Alcohol, smoking, and air pollution
- High oxidative stress and inflammation
- Poor diet lacking in sulfur-rich foods (e.g., garlic, onions, broccoli)
🧪 How to Measure Your Glutathione Levels
You don’t need a hospital visit or a complicated test. The Glutathione Index Test from VitaminTestKits.com lets you measure your antioxidant status at home using a simple dried blood spot sample. This test evaluates both reduced (active) and oxidised (inactive) glutathione — providing a clear view of your redox balance.
🔁 How to Naturally Boost Glutathione
Looking to optimise your glutathione levels? Here’s where to start:
- 🌱 Eat cruciferous vegetables like broccoli, kale, cauliflower, and Brussels sprouts
- 💊 Consider supplements like NAC (N-acetylcysteine), alpha-lipoic acid, glycine, and selenium
- 🛌 Prioritise high-quality sleep and stress reduction techniques
- 🏃♂️ Engage in regular, moderate-intensity exercise

✅ Final Word
Glutathione is more than just an antioxidant — it’s the cornerstone of your body’s defense system. Testing your glutathione status is one of the smartest steps you can take toward improving resilience, recovery, and long-term health. You can’t manage what you don’t measure.

📌 FAQ – Glutathione & At-Home Testing
What’s the difference between reduced and oxidised glutathione?
Reduced glutathione (GSH) is the active form that neutralises free radicals. Oxidised glutathione (GSSG) is the used-up form. A higher GSH:GSSG ratio means better antioxidant protection.
How accurate is the Glutathione Index Test?
Our test uses LC-MS/MS methodology on dried blood spot samples — the clinical gold standard for reliable antioxidant measurement.
When should I consider testing?
If you're fatigued, dealing with chronic stress, recovering from illness, or focused on longevity, testing your glutathione is a great starting point.
How often should I retest?
Every 3–6 months if you’re implementing lifestyle or supplement changes and want to track your redox improvements over time.
