The Active Ingredient Is: Vitamin C (Ascorbic Acid)

Vitamin C, or more simply ascorbic acid, is a water-soluble vitamin that supports a range of everyday physiological functions.

This formulation brings Vitamin C together with a phytosome complex to improve the delivery of other active components, and a quercetin phytosome is included as a secondary ingredient to support bioavailability.

What Does Vitamin C Do?

Vitamin C participates in immune system function and helps guard cells from oxidative stress, supporting everyday wellness as described in EFSA-compatible nutrient function guidance.

The vitamin also contributes to regular iron absorption, supporting energy metabolism and connective tissue maintenance as part of a balanced diet.
