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.

It is too early to know the benefits

I've been taking SRVC for about 4 years now and have only had two minor colds within that time. Everyone I've told about it and who have started taking them have also seen a huge improvement and hardly get colds any more as well!
