Product Function
1.Powerful Antioxidant Defense: Its primary role is to protect cells from oxidative stress, which is linked to aging, cancer, and numerous chronic diseases (e.g., heart disease, dementia).
2.Liver Health and Detoxification: It is a cornerstone of the liver's detoxification pathways. It is used medically to treat liver damage from conditions like fatty liver disease, alcohol abuse, and drug overdoses (e.g., acetaminophen).
3.Promotes Skin Health: It inhibits the enzyme tyrosinase, which is involved in producing melanin. This is why it is famously used for skin lightening and treating hyperpigmentation (e.g., dark spots, melasma). It also protects the skin from UV damage and promotes a healthy, radiant complexion.
4.Supports Immune Function: By optimizing the activity of immune cells, it helps the body combat infections and may modulate autoimmune responses.
Product Application
1. Dietary Supplements and Wellness:
Oral Supplements: Available in capsules, tablets, softgels, and sublingual forms. However, oral bioavailability is very poor as it is largely broken down by digestive enzymes. Newer forms like liposomal glutathione, sublingual, or S-acetyl glutathione are designed to enhance absorption.
Skin Lightening: This is a massive driver of its popularity, especially in Southeast Asia. It is taken orally or administered via IV drips (controversial due to regulatory and safety concerns) for this purpose.
2. Aesthetics and Cosmeceuticals:
Topical Serums and Creams: Included in skincare formulations for its antioxidant and brightening properties. However, penetration through the skin barrier can be a challenge.
3. Functional Foods and Beverages:
Added to certain health drinks, shots, and fortified foods marketed for "detox," "immunity," or "beauty from within," though the effective dosage in these formats is often debated.
