L-Glutathione, also known as glutathione, or in short as gluta, is an antioxidant that the body can create by itself. It is praised as “The Power of 3 Antioxidants” because it consists of three amino acids bonded together which are Glycine, Cysteine, and Glutamic. L-Glutathione is usually found within cells surrounding the nucleus. It protects cells throughout the body, including tissues and organs. It helps fight free radicals, which are the molecules that can damage the cell, that accelerate the aging process. Thus, it brightens the skin color, reduces wrinkles, and slows down aging. L-Glutathione works like an energy booster for the immune system, helping the body to dispose heavy metals and drugs. It also helps prevent the damage of light radiation, smoking and alcohol. Moreover, it helps reduces inflammation in arthritis as well as allergy.


L-glutathione is mainly found in every cell, usually in the liver, spleen, kidneys, and pancreas, as well as the lens and cornea. In plants, it is most found in asparagus, avocados, and walnuts. In addition, other types of antioxidants can increase the production of L-Glutathione in the body such as Alpha-lipoic acid, Glutamine, Methionine, Whey Protein, Vitamin B6, Vitamin B2, Vitamin C and Selenium.


L-Glutathione plays an important role in the body as follows :

  • Skin care, whitening skin : L-Glutathione has been dubbed as a molecule that amazingly brightens the skin color, protects the skin-damaging against UV rays and polluted environment. Studies have shown that L-glutathione can inhibit melanin formation and the tyrosinase operation that creates melanin or dark skin pigment to be decreased. It inhibits the metabolism of melanin, changing the synthesis of melanin from eumelanin to pheomelanin. The increased pheomelanin brightens the skin from the inside out, making the skin color lighter and more pink and tighter.

  • Antioxidants : L-Glutathione is the most powerful antioxidant. Once it enters the body, it will be converted to the enzyme Glutathione Peroxidase. It is an important antioxidant of the body in reducing the degeneration of cells in the body, enhancing the ability to eliminate foreign matter and pathogens of white blood cells. It also protects the tissues of cells in various organs not to be destroyed by free radicals.

  • Reduce dark skin, melasma and dark spots : UV-A and UV-B rays in sunlight stimulate melanin production and free radicals that destroys skin cells, causing Lipid peroxide, which is the cause of dark skin, melasma and dark spots. L-Glutathione is an antioxidant that can fights against the mechanisms of free radicals, resulting in reduced dark circles, blemishes, dark spots, and uneven skin tone.

  • Reduce wrinkles and aging skin : UV rays cause the reactive oxygen species (ROS), which is the reason of oxidative damage to the skin, making the aging skin that appears in wrinkles and dryness. L-Glutathione corrects wrinkles after UV exposure while preventing future damage, making a younger and more radiant skin.

  • Detoxification agent : L-Glutathione works as an antitoxin, antibody with the ability to neutralize a specific toxin that enter the body. It protects the liver from the damage of alcohol and enhance the function of the liver to eliminate toxins. It detoxes heavy metal toxins or insoluble toxic substances to be able to dissolve better in water and disposed more easily. Toxins that it helps detoxify such as heavy metals, volatile substances, pesticides, or some drugs such as paracetamol poisoning.

  • Strengthen immune system : L-glutathione is a part of the process of stimulating the production of white blood cells to be more efficient and abundant. It helps carry the amino acid L-alanine, which is essential to produce lymphocytes to trap and fight against environmental pollutants that infiltrates into the body in which causing illness, including cancer cells. Also, L-glutathione is found with high amounts in the thymus gland, a very important gland in the immune system.

From the above-mentioned, L-glutathione has many benefits for your body. However, L-glutathione in the body does always not constantly in enough supply. It decreased by age, damage by sunlight, exercise, strenuous activities, alcohol consumption, stress, tobacco smoke and air pollution that you encounter in your daily life. Therefore, supplement contained L-glutathione can be a great help to strengthen your body.
