The Active Ingredient Is: Vitamin C (Ascorbate Form)

Vitamin C, or ascorbic acid, is a water-soluble nutrient essential for everyday body functions including antioxidant protection and collagen formation.

This version supplies vitamin C as mineral ascorbates (calcium, magnesium and potassium ascorbates) to buffer acidity, with the ascorbic acid sourced from corn dextrose fermentation and minerals from limestone. The product is suitable for vegans and uses these buffering minerals to support gentler stomach tolerance.

What Does Vitamin C Do?

Vitamin C takes part in antioxidant protection and participates in collagen synthesis, iron absorption, and immune system support in line with EFSA guidance. Buffered forms are known for gentler stomach tolerance versus standard ascorbic acid, aiding comfortable daily use.

Dr. Hemilä from the University of Helsinki found that buffered vitamin C supports immune function in certain contexts, aligning with the ingredient's role in everyday physiological defence and tissue health.
