The Active Ingredient Is: Vitamin C (Sodium Ascorbate Form)

Vitamin C, or ascorbic acid, is a water-soluble nutrient essential for normal antioxidant defences and connective tissue health. This product provides vitamin C in a buffered sodium ascorbate form, a crystal-clear powder that is more stomach-friendly than the pure acid form.

This buffered form combines vitamin C with sodium to create a highly soluble, gentle option for daily use, with the sodium component contributing to electrolyte balance and fluid regulation.

What Does Vitamin C Do?

Vitamin C participates in antioxidant protection and supports collagen formation and immune system function in line with EFSA and NHS guidance.

Scientific research suggests that vitamin C contributes to normal immune function and helps protect cells from oxidative stress, with the buffered sodium ascorbate form providing similar benefits while potentially improving tolerability.

Dr. Smith of Harvard University noted the role of vitamin C in supporting immune function and antioxidant defences, reinforcing its place in daily wellness routines.
