About this supplement
Immune Defence and the Roles of Zinc and Vitamin C
Zinc and Vitamin C each contribute to immune function through distinct biological pathways, making them complementary rather than overlapping in their roles. Vitamin C is a water-soluble antioxidant present in high concentrations in immune cells. It supports the production and migration of white blood cells and protects them from oxidative damage generated during their own activity. Because the body does not store Vitamin C in significant quantities, regular intake is needed to maintain tissue levels. Zinc is involved in the development and function of a broad range of immune cells including neutrophils, natural killer cells and T-lymphocytes, and contributes to the maintenance of the skin and mucosal membranes that form the body's first physical barrier against pathogens.
1,000mg Vitamin C: A High-Strength Daily Dose
Standard supplement doses of Vitamin C typically sit between 80 and 200mg. Zinc + Vitamin C delivers 1,000mg per serving at 1,250% NRV — a high-strength dose in a single daily scoop. Vitamin C is water-soluble and not stored in the body in significant quantities, making consistent daily intake at a meaningful level the most reliable approach to maintaining tissue concentrations.
Zinc Bisglycinate: Chosen for Bioavailability
Zinc is available in many compound forms with different absorption characteristics. Zinc + Vitamin C uses zinc bisglycinate, a chelated form in which zinc is bound to two glycine amino acids. This form is well absorbed and well tolerated, making it a reliable choice for a high-strength daily zinc formula. Each serving delivers 25mg of elemental zinc at 250% NRV.
Two Ingredients, Focused by Design
The formula contains two active ingredients: Vitamin C and zinc bisglycinate. No additional nutrients, no fillers beyond what the microgranule format requires. For people who want a focused, high-dose immune formula rather than a broad multi-ingredient product, the simplicity is the point.
Advanced Microgranule Technology
Zinc + Vitamin C uses coated microgranules engineered for ingredient stability, no capsules and no tablets. Take the granules directly with water, or mix into yoghurt, juice, a smoothie or breakfast food. Do not mix with hot food or drinks.
Frequently asked questions
Is a scoop included?
Yes. One level scoop is your full daily serving.
How long does one container last?
30 servings, a full month supply at the recommended daily dose of one scoop.
How does this differ from the Immune formula?
Immune is a comprehensive daily formula with 20 vitamins and minerals covering immune function and a broader nutritional baseline. Zinc + Vitamin C is a two-ingredient, high-dose formula for focused immune support at significantly higher levels of Vitamin C and Zinc than Immune contains. Different tools for different purposes, and they can be used alongside each other with care around combined zinc intake.
Can I take Zinc + Vitamin C alongside Immune?
Both products contain zinc. Combined daily intake from both would exceed recommended levels. Do not take both at the same time without consulting a healthcare professional.
Is 1,000mg of Vitamin C safe to take daily?
1,000mg of Vitamin C daily is within the range used across the research literature and below the EFSA tolerable upper intake level for adults. High-dose Vitamin C is not recommended for people with a history of kidney stones or haemochromatosis. If in doubt, consult a healthcare professional.
Who should not take Zinc + Vitamin C?
Not recommended for children, during pregnancy or breastfeeding unless advised by a healthcare professional. High-dose Vitamin C may not be suitable for people with kidney stones or haemochromatosis. Do not combine with other zinc-containing supplements. Consult a healthcare professional before use if you are taking medication or have a medical condition.
How should I store it?
In the original sealed packaging, in a dry place away from light at +5 to +25°C.
