Vitamin C, D3 and Zinc, Immunity 100 Capsules, NutriBiotic

NutriBiotic Vitamin C, D3 & Zinc — a pharmaceutical grade immune support trio delivering Vitamin C 1,500mg (as 100% pharmaceutical grade L-ascorbic acid USP-FCC), Vitamin D3 125mcg/5,000 IU (as cholecalciferol), and Zinc 40mg (as zinc sulfate) per 2-capsule serving, for comprehensive immune defence, antioxidant protection, and tissue health. Non-GMO. Gluten-free. No fillers, binders, or preservatives. 100 capsules — 50 servings.

Why

When it comes to immune health, Vitamin C, D3, and Zinc are the gold standard trio — each playing a distinct and essential role, together covering the immune system from multiple angles. Vitamin C is the body’s primary water-soluble antioxidant and a critical cofactor for immune cell function and collagen synthesis. Vitamin D3 activates innate and adaptive immune defences and is one of the most commonly deficient nutrients in modern populations. Zinc is essential for immune cell development, communication, and inflammatory regulation. NutriBiotic uses only 100% pharmaceutical grade L-ascorbic acid USP-FCC — the same standard used in medicines — with no corn residue, plant antigens, or protein impurities, packaged in a NitroPak® bacteria-free environment to preserve freshness and potency. For adults only. Note: zinc at 40mg (360% DV) is a high therapeutic dose — long-term use may deplete copper; consult a healthcare professional before use.

Formula Highlights

• Vitamin C 1,500mg per serving (as 100% pharmaceutical grade L-ascorbic acid USP-FCC, 1,670% DV) — the body’s primary water-soluble antioxidant; essential cofactor for immune cell function (neutrophils, lymphocytes, and natural killer cells); required for collagen synthesis (skin, cartilage, blood vessels, and connective tissue); pharmaceutical grade USP-FCC standard with no corn residue, plant antigens, or protein impurities
• Vitamin D3 125mcg / 5,000 IU per serving (as cholecalciferol, 625% DV) — the most bioavailable form of Vitamin D; activates both innate and adaptive immune defences via the vitamin D receptor (VDR); supports healthy bones (calcium absorption), cognitive function, and mood; one of the most commonly deficient nutrients in modern populations, particularly in low-sunlight regions
• Zinc 40mg per serving (as zinc sulfate, 360% DV) — an essential trace mineral required for the development and function of immune cells (T-cells, B-cells, natural killer cells); supports inflammatory regulation and wound healing; zinc sulfate is a well-absorbed, bioavailable form; note: 40mg is a high therapeutic dose — long-term use may deplete copper

Warnings

For adults only. Zinc 40mg is a high therapeutic dose — long-term use of high-dose zinc may deplete copper; consider supplementing with copper if using long-term. Vitamin D3 5,000 IU is a high therapeutic dose — consult a healthcare professional before use, particularly if you have hypercalcaemia or conditions affecting calcium metabolism. High-dose Vitamin C may cause digestive discomfort or loose stools in sensitive individuals — reduce dose if this occurs. Consult a healthcare professional before use if pregnant, breastfeeding, or taking prescription medication. Keep out of reach of children. Store in a cool, dry place.
