The Active Ingredient Is: Vitamin C (Ascorbic Acid)

Vitamin C is a water soluble nutrient important for ordinary body function, including antioxidant protection and collagen formation for connective tissues.

This formula includes citrus bioflavonoids, which help to boost vitamin C absorption and offer synergistic antioxidant benefits.

What Does Vitamin C Do?

Vitamin C helps with normal immune function and participates in energy-yielding metabolism, while supporting antioxidant protection throughout your body. Dr. Smith of Harvard University notes the role of vitamin C in immune support and collagen synthesis as part of its broader functions.

The pairing of vitamin C with citrus bioflavonoids helps its uptake and activity, helping to keep capillary and connective tissue health in line with EFSA guidance.
