L-Glutathione
Uses of L-Glutathione
L-Glutathione is a naturally occurring antioxidant used to help protect cells from oxidative stress.
L-Glutathione is commonly used for:
• Oxidative stress and cellular protection: Helps neutralise harmful free radicals and reactive oxygen species, protecting cells and tissues from damage caused by ageing, chronic diseases, and environmental toxins.
• Liver disorders: May be used as supportive therapy in certain liver conditions.
• Immune support: Supports normal immune cell function through its role as an antioxidant.
• Chemotherapy support: Used in some clinical settings to help protect healthy cells from oxidative damage during cancer treatment.
• Skin health: Topical and oral forms are used for antioxidant protection and have been studied for their effects on skin pigmentation.
Side effects of L-Glutathione
- Nausea
- Vomiting
- Abdominal cramps
- Diarrhea
- Allergic reactions such as rash or hives
How L-Glutathione works
- L-Glutathione is a tripeptide antioxidant composed of three amino acids: glutamate, cysteine, and glycine. It is produced naturally by the body and is found in nearly every cell.
- It works primarily as an antioxidant, meaning it neutralises harmful molecules called free radicals and reactive oxygen species (ROS). These molecules are produced during normal cellular processes and may also increase due to factors such as pollution, stress, and ageing. By donating electrons to neutralise these molecules, Glutathione helps protect cell membranes, proteins, and DNA from oxidative damage.
- In the liver, Glutathione plays a central role in detoxification. It binds to certain toxic compounds, heavy metals, and harmful drug metabolites, converting them into water-soluble forms that can be safely excreted from the body via bile or urine. This is known as conjugation.
- Glutathione also recycles other antioxidants such as Vitamins C and E, restoring their ability to continue fighting oxidative damage after they have been used.
- In the immune system, it supports the activity and proliferation of immune cells, helping the body mount effective responses to infections.
