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.

La vitamina C è un potente antiossidante, e non provocando effetti collaterali per un uso eccessivo direi che è un ottimo prodotto per l'inverno

I have taken Vitamin C for many years when I have felt a cold coming on and very often it has stopped it, most times

I like the sustained release aspect of this tablet as the body does not store Vitamin C, and I know Vitamin C is really good for the body but I cannot explain how it helps me. I just trust that it does.
