Vitamin C, also known as ascorbic acid, is a water-soluble vitamin essential for normal physiological function and antioxidant protection.

This form is presented as ascorbic acid for bioavailability and stability in a vegetarian tablet format.

What Does Vitamin C Do?

Vitamin C helps maintain normal immune function and supports collagen formation and iron absorption, in line with EFSA and NHS guidance.

Dr. Carr of University of Milan found that vitamin C contributes to immune cell function and antioxidant protection in the body, supporting overall health in daily activities.
