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.

Time-Release Vitamin C

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 Together by Design

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.

Clinical Research

Synergistic antioxidant activity of Vitamin C, zinc, and copper: complementary mechanisms in cellular defence

Free Radical Biology and Medicine, 2012

This study examined the complementary antioxidant mechanisms of Vitamin C, zinc, and copper at the cellular level. Vitamin C was confirmed as a primary water-soluble antioxidant that directly neutralizes free radicals and regenerates oxidized Vitamin E. Zinc was found to support antioxidant enzyme systems and protect cell membranes from lipid peroxidation. Copper, as a required cofactor for copper zinc superoxide dismutase (SOD), was identified as essential for the enzymatic dismutation of superoxide radicals one of the body's primary cellular antioxidant defence mechanisms. The authors concluded that the combination of Vitamin C, zinc, and copper provides a multi mechanism antioxidant defence system that is more comprehensive than any single nutrient alone, supporting the rationale for their co formulation in immune and antioxidant support products.

Zinc induced copper deficiency: a review of mechanisms and clinical implications

Journal of Trace Elements in Medicine and Biology, 2008

This review examined the well documented competitive interaction between zinc and copper for intestinal absorption via shared transport proteins, with particular focus on the clinical implications of zinc induced copper depletion. High dose zinc supplementation without adequate copper was found to progressively deplete copper status, impairing copper dependent immune cell function, copper zinc superoxide dismutase (SOD) activity, and iron metabolism. The authors reviewed clinical evidence establishing the 15:1 zinc-to copper ratio as a practical guideline for maintaining healthy mineral balance during zinc supplementation. The review concluded that co supplementation of zinc with copper at an appropriate ratio is essential for preventing zinc induced copper depletion and maintaining the full spectrum of immune and antioxidant functions dependent on both minerals.

Vitamin C and immune function: mechanisms and clinical evidence

Nutrients, 2017

This comprehensive review evaluated the role of Vitamin C in supporting immune function across multiple mechanisms. Vitamin C was found to support the production and function of white blood cells including neutrophils, lymphocytes, and natural killer cells, and to protect immune cells from oxidative damage generated during immune responses. The authors noted that Vitamin C is actively transported into immune cells at concentrations far exceeding plasma levels, indicating a specific functional role in immune cell activity. The review also examined the evidence for time release Vitamin C formats, noting that sustained-release delivery supports more consistent plasma Vitamin C levels compared to immediate release formats at equivalent doses. The authors concluded that Vitamin C is an essential micronutrient for immune function with a well established evidence base.

Frequently Asked Questions

What is Vitamin C with Zinc and Copper used for?

This formula combines vitamin C, zinc, and copper to help support normal immune function, antioxidant protection, connective tissue formation, and overall health.

How does Vitamin C support the immune system?

Vitamin C is an essential nutrient that contributes to the normal function of the immune system and acts as an antioxidant that helps protect cells against oxidative damage.

Does Vitamin C provide antioxidant support?

Yes. Vitamin C is an antioxidant that helps protect cells against oxidative stress caused by free radicals.

When is the best time to take Vitamin C with Zinc and Copper?

It is generally best taken with food, which may improve digestive tolerance, particularly for zinc.

Who may consider taking a time release Vitamin C, Zinc and Copper supplement?

It may be suitable for adults looking for convenient daily support for immune health, antioxidant protection, connective tissue health, and overall nutritional wellness.
