Ascorbic acid functions as an antioxidant and a cofactor for collagen formation and neurotransmitter synthesis.
Caution: High doses may cause digestive discomfort in some people due to osmotic effects.
Magnesium serves as a cofactor in hundreds of enzymatic reactions involved in energy production, muscle and nerve function, and electrolyte balance.
Caution: May loosen stools at higher intakes; take with food if sensitive.
Bioflavonoids provide polyphenols that may help protect vitamin C from oxidation and support capillary integrity.
Caution: May interact with certain medications due to polyphenol content; discontinue if unusual sensitivity occurs.
Vitamin C supplies antioxidant activity and supports connective tissue, while magnesium contributes to energy metabolism and neuromuscular function; combining them as magnesium ascorbate makes the vitamin C non-acidic. Citrus bioflavonoids add polyphenols that may help stabilize vitamin C and complement vascular and antioxidant support.
Label Warning: If you are pregnant, may become pregnant, or breastfeeding, consult a healthcare professional before use.
