L-Glutathione

L-Glutathione (L-glutathione) is the biologically active form of glutathione, a tripeptide composed of three amino acids: glutamine, cysteine, and glycine. It is a powerful antioxidant found in every cell of the human body and is essential for various cellular processes.

Functions of L-Glutathione:

Antioxidant Defense: L-Glutathione helps protect cells from oxidative damage by neutralizing free radicals and reactive oxygen species.

Detoxification: It is crucial for detoxifying harmful substances in the liver, aiding in the removal of toxins, heavy metals, and other pollutants from the body.

Поддержка иммунной системы: L-Glutathione supports the immune system by enhancing the activity and proliferation of white blood cells, which are essential for fighting infections and diseases.

Regeneration of Other Antioxidants: It helps regenerate other antioxidants, such as vitamins C and E, ensuring they remain effective in combating oxidative stress.

Cellular Health and Function: L-Glutathione plays a role in DNA synthesis and repair, protein synthesis, and cell cycle regulation.

Enzyme Function: It acts as a cofactor for various enzymes, aiding in numerous metabolic processes within the body.

Benefits of L-Glutathione:

Reduces Oxidative Stress: By neutralizing free radicals, L-Glutathione helps lower oxidative stress, which is associated with numerous chronic diseases, including diabetes, cancer, and cardiovascular diseases.

Improves Skin Health: It can lighten skin tone, reduce hyperpigmentation, and improve overall complexion by reducing melanin production and protecting against UV radiation.

Enhances Athletic Performance: L-Glutathione can enhance physical performance and recovery by reducing muscle fatigue and damage during and after exercise.

Supports Brain Health: It protects neurons from oxidative stress, potentially improving cognitive function and reducing the risk of neurodegenerative diseases such as Alzheimer’s and Parkinson’s.

Boosts Immune Function: L-Glutathione strengthens the immune system, helping the body to efficiently fight off infections and illnesses.

Promotes Liver Health: It aids in liver detoxification processes, protecting the liver from damage caused by alcohol, drugs, and environmental toxins.

Improves Insulin Sensitivity: Some studies suggest that L-Glutathione may improve insulin sensitivity, which can benefit individuals with diabetes or metabolic syndrome.

Maintaining adequate levels of L-Glutathione can be achieved through a diet rich in sulfur-containing foods, such as garlic, onions, and cruciferous vegetables, or through supplementation and adopting a healthy lifestyle with regular exercise and sufficient sleep.
