Synergistic antioxidant activity of Vitamin C, zinc, and copper: complementary mechanisms in cellular defence
Free Radical Biology and Medicine, 2012
Vitamin C, zinc, and copper in a single daily capsule each in a form chosen for absorption and tolerability. Vitamin C 850 mg as time release ascorbic acid. Zinc 15 mg as zinc bisglycinate. Copper 1 mg as copper bisglycinate. Supports immune function, antioxidant protection, and collagen formation.
Vitamin C is water soluble and rapidly excreted at higher doses. The hydroxypropyl methylcellulose matrix in this formula slows the release of ascorbic acid over several hours supporting more consistent blood levels throughout the day, reducing urinary excretion of excess Vitamin C, and improving gastric tolerability compared to immediate release formats.
Zinc and copper compete for absorption via shared intestinal transport proteins. High dose zinc without adequate copper can progressively deplete copper status, impairing immune cell function and antioxidant enzyme activity. This formula provides both minerals in a 15:1 ratio a meaningful zinc dose with copper maintained in balance. Both are delivered as bisglycinate chelates, bound to glycine for enhanced absorption and reduced gastric irritation compared to inorganic mineral salts.
