Glutathione is a naturally occurring antioxidant made by the body from three amino acids: glutamate, cysteine, and glycine. It is found in almost every cell and plays a key role in protecting cells from oxidative stress and supporting normal cellular function.

What does glutathione do?

Glutathione is involved in many important biological processes, including:

🛡️ Antioxidant defense – helps neutralize free radicals and reduce oxidative stress.
🧪 Detoxification – supports the liver’s normal detoxification processes by helping metabolize certain drugs and toxins.
🧬 Cellular health – helps protect proteins, lipids, and DNA from oxidative damage.
🦠 Immune function – contributes to the normal function of immune cells.
⚡ Mitochondrial function – helps maintain healthy energy-producing structures within cells.
♻️ Vitamin recycling – helps regenerate antioxidants such as vitamins C and E after they have been used.

Areas Being Studied

Researchers are investigating glutathione for its potential role in:

Healthy ageing.
Recovery from oxidative stress.
Liver health.
Neurodegenerative diseases.
Exercise recovery.
Immune function.
Certain chronic medical conditions associated with low glutathione levels.

Skin Health

Glutathione has also been studied for its effects on skin pigmentation. Some studies suggest it may influence melanin production, but the evidence is mixed, and there is insufficient high-quality evidence to conclude that glutathione is a safe or effective skin-lightening treatment.

What Does the Evidence Show?

Research supports that:

Glutathione is essential for normal cellular function.
Low glutathione levels are associated with several diseases and ageing.
Some medical conditions may benefit from therapies aimed at restoring glutathione levels, but this depends on the condition and treatment approach.
For healthy individuals, there is limited evidence that glutathione supplementation provides substantial health or performance benefits.

Summary

Glutathione is a naturally occurring antioxidant that helps support:

✔️ Protection against oxidative stress
✔️ Normal liver detoxification processes
✔️ Immune system function
✔️ Healthy cellular function
✔️ Mitochondrial health
✔️ Recycling of other antioxidants
