Glutathione (GSH) is a tripeptide built from three amino acids (glutamate, cysteine, and glycine). It is the most abundant antioxidant inside human cells, where it neutralizes reactive oxygen species, supports liver detoxification, recycles vitamins C and E, and helps immune cells function normally. Levels decline with age, chronic illness, toxin exposure, and poor nutrition. Live Vital offers physician-prescribed glutathione to help restore depleted levels.

Glutathione acts as the primary antioxidant inside cells, directly neutralizing free radicals, supporting Phase II liver detoxification, and regenerating vitamins C and E so they can keep working. It also helps maintain the balance immune cells need, including natural killer (NK) cell activity, and supports mitochondrial function tied to cellular energy. It may also support skin elasticity and reduce hyperpigmentation.

Those looking to support overall antioxidant and detox capacity, patients seeking added immune support, those interested in skin tone and elasticity, people with elevated oxidative stress from age, illness, or toxin exposure, and patients on a peptide protocol who want an antioxidant foundation alongside it.

Many patients report early immune-related improvements within 2 to 4 weeks, with skin and oxidative-stress benefits typically emerging around 8 to 12 weeks. Sustained antioxidant support generally requires ongoing use.

Glutathione is generally well tolerated. Commonly reported side effects are mild bloating or cramping (oral form), injection site irritation, temporary flushing (injectable), and, rarely, a sulfurous taste or smell. It is not appropriate with known hypersensitivity to glutathione, during pregnancy or breastfeeding without physician guidance, with asthma (inhaled forms may trigger bronchospasm), or for transplant recipients on immunosuppressants. Glutathione is not FDA-approved as a prescription drug for these uses and, when prescribed, is done off-label under physician supervision after intake and informed consent. Standard oral glutathione is largely broken down in the gut, so Dr. Taylor determines the right form and route for you.
