What is Sustained Release Vitamin C?

  • Suitable for Vegetarians
  • Suitable for Vegans
  • Gelatin Free
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.

Key Features

  • Steady release of vitamin C throughout the day.
  • Made using a special process for slow release.
  • With added zinc for immune system support.

One to two tablets a day with food.

Taking this supplement as an adjunct to a prescription medication. If successful after six month trial both will become permanent.

Forgot to order these for a while and tried a different brand. Ended up with a really bad cold/flu which only started to improve when I started taking the healthspan vitamin c tablets. Always manage to keep clear of most cold bugs when taking these.
