What does Vitamin C do and why choose pharmaceutical grade?

Vitamin C (ascorbic acid) is one of the most essential nutrients for human health — and one that the human body cannot produce on its own. It must come entirely from diet or supplementation. As a powerful water-soluble antioxidant, Vitamin C protects cells from oxidative damage, supports immune function, is critical for collagen synthesis (the structural protein that gives strength to skin, bones, cartilage, and blood vessels), enhances iron absorption, supports folate metabolism, and is involved in the biosynthesis of neurotransmitters. NutriBiotic’s Ascorbic Acid is manufactured to USP-FCC (United States Pharmacopeia – Food Chemical Codex) pharmaceutical grade standards — the same purity level used in pharmaceutical manufacturing. Crucially, it contains absolutely no corn residue, plant antigens, or protein impurities — making it safe for those with corn or yeast sensitivities who cannot tolerate most commercial Vitamin C products. The highly soluble crystalline powder dissolves instantly in water or juice, allowing flexible, precise dosing. At 2,500mg per ½ tsp serving, it delivers a meaningful therapeutic dose in a small, easy-to-measure amount.

Note on acidity

This is the standard acidic form of Vitamin C (pH 2.1). Those with sensitive stomachs, acid reflux, or digestive discomfort may prefer our NutriBiotic Sodium Ascorbate — the pH-neutral (7.1), non-acidic buffered form that delivers the same Vitamin C benefits without the acidity.
