What is L-Glutathione?
L-Glutathione (or glutathione) is a powerful antioxidant made up of three amino acids: glutamine, cysteine and glycine. It is found in almost every cell in our body and acts as a ‘shield’ against oxidative damage caused by free radicals, toxins and stress. It is produced by the liver, but factors such as age, poor diet and pollution can reduce its levels. Think of it as the ‘internal cleanser’ that keeps your cells in shape.
There are two forms: reduced (active) and oxidised (inactive). The L-Glutathione we consume or supplement is the active form, ready to work.
What is L-Glutathione good for?
This antioxidant has impressive science-backed benefits:
- Detoxification: it helps the liver eliminate toxins, heavy metals and chemicals, according to studies in Toxicology (2018). Key for those exposed to pollution or processed diets.
- Cellular protection: Neutralises free radicals, preventing premature ageing and damage to tissues such as skin, eyes and lungs.
- Immune health: Boosts defences by supporting white blood cells, according to Antioxidants (2020).
- Radiant skin: By reducing oxidative stress, it can lighten blemishes and improve tone, a popular effect in natural cosmetics.
- Energy and recovery: By protecting the mitochondria (the cellular ‘batteries’), it improves vitality and aids muscle recovery.
In short, L-Glutathione is a multitasker that cleanses, protects and revitalises.
L-Glutathione supplementation: Is it necessary?
Our body manufactures glutathione, but its levels drop with age (after 40), chronic stress, illness or poor diet. This is where L-Glutathione supplementation comes in:
When to consider: if you have constant fatigue, exposure to toxins (smoke, pesticides), liver problems or want an antioxidant boost.
Forms: Capsules (100-600 mg/day), liposomal (better absorption) or intravenous (in clinics, more potent but expensive). Oral is less effective alone, so combine with vitamin C (boosts its action).
Benefits: Studies suggest it raises blood levels, improving detoxification and skin in 4-12 weeks.
Precautions: Safe in low doses, but consult a doctor if you are pregnant, on medication or have specific conditions.
Not everyone needs it. If your diet is rich in its precursors, you may not need supplementation.
Where do we find it in the diet?
Although we do not consume L-Glutathione directly in large amounts, certain foods contain it or stimulate its production:
Direct sources: Spinach, avocado, asparagus (low amounts, but fresh are key).
Precursors:
Cysteine-rich proteins: chicken, eggs, fish.
Garlic, onion (rich in sulphur, an essential component).
Broccoli, cauliflower (cruciferous vegetables that boost glutathione).
Extras: Fruits with vitamin C (oranges, kiwis) and nuts (selenium) help to recycle it.
A dish with salmon, spinach and a touch of garlic is already working for your glutathione.
Conclusion: The power of L-Glutathione
L-Glutathione is an essential antioxidant that detoxifies, protects and rejuvenates from within. What it's good for ranges from a healthy liver to glowing skin, and while L-Glutathione supplementation can be helpful, a varied diet is usually enough for most.
