Vitamin C is an essential vitamin however the body does not store Vitamin C, so a regular daily intake is required. Each 500mg (625% NRV) tablet is made using a special process that ‘meshes’ the vitamin with a plant cellulose so that it breaks down gradually to release vitamin C. Zinc is also included as it contributes to the normal function of the immune system.

Because Vitamin C is a water-soluble vitamin, it is not stored in the body for very long. This means that a regular intake is needed to keep the levels topped up. The benefits of Vitamin C are many and varied, they include; the support of the immune system, the reduction of tiredness and fatigue and the normal function of the nervous system.
