Glutathione is a natural substance produced by the body from three amino acids: glycine, cysteine, and glutamic acid.

It is made in the liver and plays several important roles, including tissue repair, the production of chemicals and proteins, and supporting the immune system.

According to medical experts, people use glutathione to reduce the effects of aging, improve skin texture, and manage various heart and liver conditions. However, there is no clear evidence proving its effectiveness for these purposes.

Researchers say glutathione may only be effective in a specific situation—when it is administered directly into the bloodstream through injections (IV). It may help reduce nerve damage caused by strong cancer drugs such as cisplatin.

Side effects and precautions:

Taking glutathione in a daily dose of 500 mg for up to two months is considered possibly safe.

Applying it directly to the skin may cause itching or allergic reactions in some individuals.

Dosage and intake

Medical experts note that there is no well-established scientific guidance on the appropriate dosage of glutathione. Since natural supplements are not always risk-free, it is important to consult a doctor before using them
