This combination is used to prevent or treat vitamin C and B3 (niacinamide) deficiency, support skin health in conditions like acne, hyperpigmentation, and photoaging, and provide antioxidant protection against free radical damage.
Ascorbic acid (vitamin C) acts as a potent antioxidant and is essential for collagen synthesis and immune function, while niacinamide (vitamin B3) supports skin barrier function, reduces inflammation, and helps regulate sebum production. Together they provide complementary benefits for skin health and cellular protection.
Generally well-tolerated when taken at recommended doses, though high doses of vitamin C may cause gastrointestinal upset in some individuals. Niacinamide is usually preferred over niacin as it causes fewer flushing side effects. Consult a healthcare provider before use if pregnant, breastfeeding, or taking other medications, as vitamin supplements can interact with certain drugs.
