The Active Ingredient Is: Vitamin C (Sodium ascorbate form)

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that functions as an antioxidant and supports normal physiological processes. The sodium ascorbate form is a buffered version, and this presentation is gentler on the stomach for some users.

This form provides a vitamin C source that is commonly used for immune support and general antioxidant benefits, with buffered sodium to aid tolerability. The crystalline powder is designed for easy dissolution and use as a versatile vitamin C source.

What Does Vitamin C (Sodium ascorbate form) Do?

Vitamin C aids in normal immune system function and helps protect cells from oxidative stress, with supporting roles in collagen synthesis and iron absorption. EFSA and NHS guidance recognise these basic physiological functions as part of vitamin C’s normal role in the body.

Research suggests that vitamin C from sodium ascorbate can offer comparable bioavailability to other forms while potentially improving gastrointestinal tolerability, contributing to its practical use in daily nutrition. Dr. Hemilä of the University of Helsinki noted the broader immune-supportive context of vitamin C within this nutrient class.
