Thompson's Ultra C, an advanced form of Vitamin C, is easier to absorb ino the body, and gentler on the stomach than other Vitamin C complexes that use highly acidic ascorbic acid (pH 2.4).
Thompson's state-of-the-art, advanced Poly-ascorbate form has a clear advantage over ordinary Vitamin C. As well as better absorption, Ultra C supplies calcium, magnesium, potassium and zinc, minerals that are often excreted and lost when Vitamin C increases in the body.

Ultra C also provides the valuable cofactors Bioflavonoids, Rosehips and Zinc to further enhance the action of the complex.
Vitamin C's primary function is the manufacture of collagen, which is a crucial protein in the connective tissue, cartilage and tendons that hold the body together. So as well as a powerful immune booster, Vitamin C is useful for repairing wounds, preventing bruising and keeping gums healthy. Vitamin C also has a critical role in the manufacture of certain nerve transmitting substances and hormones, and the absorption and use of other nutritional factors.

Vitamin C affects immune function by enhancing white blood cell activity and increasing interferon levels and antibody responses. During times of chemical, emotional, physical or psychological stress, the urinary system excretes Vitamin C in significant amounts, thereby increasing the body’s need for this vitamin. Vitamin C is the first line antioxidant protection, making it one of our most important antioxidant nutrients.
Indications for Use:

Vitamin C benefits the body in so many ways. It helps boost immunity, and as a powerful antioxidant is guards against the ravages of pollution, cigarette smoke and stress. It helps wounds heal quickly and reduces the risk of cataracts. Vitamin C may assist with the treatment of colds by reducing the severity of symptoms and speeding recovery. It may also assist in the relief of hayfever and allergies.
A safe recommendation during pregnancy is 500mg daily.

I swear by taking 1000mg's of Vitamin C a day. When I feel a cold coming on, I quadruple that and have four tablets spread throughout the day, for the first 3-4 days of a cold (my understanding is you should only take this much vitamin C for a short period of time). I also firmly believe it keeps my MS under far more control than it would be under without it. Great product. :)

I'm really happy to find a vitamin C supplement that is gentle on the digestive system. I can't eat citrus fruit, kiwifruit or even fresh tomatoes or drink orange juice, as they all irritate my mouth. Ultra C is the one supplement I'd hate to do without, as it has so many benefits.

I so believe in the value in supplementing daily wiht Vit c as our body does not store it. I take up too 4000mg daily 7 days a week and more depending on what else I'm endulging in :)I do not get unwell so Ultra C is well worth it and awesome value! (HEALTHPOST response: great that this is working for you Anne. This is an unusually high dose and we would advise people to always increase or decrease dosages gradually to avoid any potential problems)
