Tink,
there is a lot of evidence that has long been forgotten or fobbed off (because it wouldn't make as much money says my cynical side) that vitamin C is one of the best ways to protect from disease. They've found that large doses of intravenous vit C given to cancer patients makes them more likely to go into remission by almost 300%, and a lot of doctors from the 1930's to the 1960's found 1000mg of vit c every 6 hours cured measles and polio. Of course then the vaccinations came onto the market and no further study was allowed to get off the ground and any attempts since have had to deal with some really unreasonable aggression and is considered career suicide. It's a shame it's not about health! Vitamin D is a natural steroid too and very helpful in healing. In the olden days the nurses in the hospital used to wheel all the patients out onto the patio of the hospitals and give their sore bits some sun (morning or late afternoon of course). They've recently found that there is a link with vit d deficiency and MS.

Health begins in the gut! Good luck
