IV glutathione, alpha-lipoic acid (ALA), zinc, and vitamin C are commonly combined in immune-boosting IV therapies (often called "immune support," "super immune," or "detox/immune" drips) in wellness and integrative clinics. This combo leverages their antioxidant, anti-inflammatory, and immune-modulating properties for synergistic effects. IV delivery allows higher doses and faster absorption than oral forms, bypassing digestion for direct bloodstream access—popular during cold/flu season, stress, recovery from illness, or general immune maintenance.
