Quali-C, a DSM Nutritional Products trademark, guarantees vitamin C produced exclusively in Scotland via an ISO 9001 and FSSC 22000 certified biofermentation process. Unlike most market vitamin C from Chinese industrial synthesis, Quali-C offers full traceability from raw material to finished capsule, and is bio-identical to the vitamin C naturally found in fresh fruit and vegetables — with a reduced carbon footprint.

Vitamin C contributes to normal immune function and the reduction of tiredness and fatigue. It contributes to normal collagen formation, a structural protein essential for skin, cartilage, bones and gums. Its antioxidant power helps protect cells from oxidative stress, and it supports plant-based (non-haem) iron absorption — a notable benefit for vegetarians and vegans.

Each pullulan vegetable capsule contains 500mg L-ascorbic acid Quali-C. The recommended daily dose is 2 capsules (1,000mg, 1,250% NRV). No excipients at all — no magnesium stearate, titanium dioxide, maltodextrin or nanoparticles; the only component besides ascorbic acid is the plant-based pullulan capsule shell. No GMOs, gluten, lactose or major allergens. The 300-capsule format covers 5 months at the standard 2-capsule dose.

Take 1 to 2 capsules a day with a large glass of water, preferably with a meal — breakfast or lunch is recommended, as vitamin C can have a mild stimulating effect for some if taken in the evening. Splitting the dose (one capsule morning, one at midday) can optimise absorption.

Does not replace a varied, balanced diet or healthy lifestyle. Do not exceed the recommended daily dose. Keep out of reach of young children. Those prone to oxalate kidney stones should consult their doctor before prolonged high-dose use. Pregnant or breastfeeding women should seek medical advice. Store tightly closed in a cool, dry place away from direct light.

What’s the difference from standard vitamin C?

Quali-C is L-ascorbic acid produced in Scotland by biofermentation, with full traceability and pharmaceutical-grade certification, unlike most market vitamin C produced in China by chemical synthesis with limited process transparency.

Can I take Quali-C vitamin C year-round?

Yes — the body doesn’t store it and eliminates excess via urine, so continuous supplementation at the recommended dose is fine; the 300-capsule format is designed for an uninterrupted, prolonged course.

Is it suitable for vegans and sensitive individuals?

Yes — fully vegan (biofermented L-ascorbic acid, pullulan plant-based capsule), with no gluten, lactose, soy or major allergens, and no excipients that could trigger reactions in sensitive digestive systems.
