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.

I think Vitamin C is a must - and the sustained release form of tablet means that you swallow just one tablet (which I take immediately after breakfast so I don't forget it) and it keeps working for about 4-5 hours, gently releasing a little bit of tablet at a time inside you. Because it is a very strong tablet (about the quantity of a complete tube that you find in chain stores) so you only need one-a-day. But if I have something wrong with me, like a cold, I take 3-a-day. You cannot over-dose, as the surplus just gets passed out of your body in your urine. It helps a cold to go in about 3-days flat, or the flue. I once had an abscess on my tooth, which was so very painful (as you would all know) and the Dentist wanted me to take antibiotics for it (which incidentally kills all your vitamins in your body) so I refused, saying I would take Vit. C for it. The Dentist scoffed and said that would not work. I told him that it would be cleared up in 3-days flat, and I would come back and prove it to him....which I did. He was absolutely amazed and could not believe it. It upholds the immune system, which is the most important part, as it fights any disease. I am a very fit lady in my 80's and my children say I am a living example of vitamins, of which I take quite a few. J.L.

Without the sustained-release vitamin C tablets from Healthspan I acquire colds/ sore throats after4/5 days. With them I very rarely have a 'snuffle'

22 July 2016

Use these alongside the Vitamin B

I have been taking this product for several years & it seems to work well.

I find the sustained release vitamin C helps me lots, I have them all year round, and I'm absolutely sure they help me keep my immune system going, as I work in a high school and since using them, I have managed to stave off a few bug's that have been around me.

A good product in manageable packaging.

A great boost for the winter months. I find it does help to keep colds at bay

18 July 2016

Have been using these for years very good

18 July 2016

I have begun use over the past couple of weeks and am very happy with results. Appears to be the same effect as with my previous vit C pills bought in the USA. I had tried some pills obtained in Germany and they had a negative affect so I threw them all out after a trial week of consumption.
