Vitamin C (L-ascorbic acid) is the most widely used vitamin ingredient in the world — an essential nutrient and antioxidant at the heart of immunity, collagen-support and general-wellness formulations, and equally important in food processing as additive E300 for antioxidant protection, colour stabilisation and flour treatment. We supply high-purity ascorbic acid meeting USP, EP, BP and FCC monographs (99.0–100.5% assay) in crystalline, fine-powder and ultra-fine mesh options, alongside direct-compression (DC-97) granules and coated grades for tablet manufacturing. Every lot ships with a full Certificate of Analysis covering assay, heavy metals and microbiological safety. Kosher and halal certified material is available on request. Standard export packing is 25 kg fibre drums or cartons with double food-grade liners, and we handle the complete export document set — COA, certificate of origin and shipping documents — for smooth import clearance (HS 2936.27).
