L-Glutathione
An antioxidant marketed to support cellular defence, detoxification, and skin brightening
Forms
Capsules, tablets, sublingual, and liposomal forms; also marketed as IV or injectable products. The reduced (GSH) form is most common
Advantages
Glutathione is the body's main antioxidant; liposomal and sublingual forms may absorb better than standard capsules
Disadvantages
Standard oral glutathione is poorly absorbed; evidence for skin-lightening and general health benefits is limited and often from small or short studies
Side effects
Generally well tolerated by mouth; possible bloating, cramps, or loose stools, and occasional skin rash
Interactions
Limited interaction data; discuss with a professional if on medication or chemotherapy, as antioxidants may theoretically interfere with some treatments
At-risk groups
Pregnant or breastfeeding women and people on chemotherapy should seek medical advice; avoid unregulated injectable products
Cautions
IV or injectable glutathione, often used for skin whitening, is poorly regulated and has been linked to serious harm, so avoid unsupervised injectable use; caution with inhaled forms in asthma
