The Active Ingredient Is: Vitamin C (Calcium Ascorbate)

Vitamin C, also known as ascorbic acid, is a water soluble nutrient essential for normal physiological functions. In this product it is provided as a buffered calcium ascorbate complex, a gentler, non acidic form designed for broad tolerability.

This formulation combines calcium with ascorbate, delivering a buffered vitamin C complex that is compatible with vegetarian capsules and free from common allergens.

What Does Vitamin C (Calcium Ascorbate) Do?

Vitamin C participates in normal antioxidant processes and supports immune function as part of a balanced diet, in line with EFSA guidance. It also plays a role in connective tissue formation and contributes to normal energy yielding metabolism.

In this buffered form, vitamin C is provided in a manner designed for stomach comfort and compatibility with vegetarian lifestyles, aligning with product goals of quality and tolerability.
