Vitamin C acts as an antioxidant and cofactor for collagen and carnitine synthesis, and Ester-C (calcium ascorbate with metabolites) is formulated to be non-acidic and may be better retained in cells.
Caution: High-dose vitamin C may cause digestive discomfort in some people; take with food to reduce the chance of stomach upset.
Citrus bioflavonoids are plant polyphenols that may help stabilize vitamin C and support antioxidant activity in tissues.
Caution: May interact with certain medications due to polyphenol content; separate from medications if sensitivity is noted.
Rutin is a flavonoid that may help support capillary integrity and complement vitamin C’s antioxidant actions.
Caution: May cause mild digestive upset in sensitive individuals; reduce dose or take with food if discomfort occurs.
Acerola provides natural vitamin C and polyphenols that may add to overall antioxidant capacity.
Caution: Contains natural fruit compounds; those sensitive to fruit extracts should monitor for tolerance.
Rose hips provide vitamin C–related constituents and polyphenols that may support antioxidant balance.
Caution: May cause mild gastrointestinal discomfort in some users; take with food if needed.
Vitamin C supplies the primary antioxidant and enzymatic cofactor activity, while citrus bioflavonoids and rutin add complementary polyphenols that may help protect tissues and support capillary function. Acerola and rose hips contribute additional natural vitamin C–related compounds that can reinforce overall antioxidant support.
