Zinc with vitamin C - immune system

The knowledge that vitamin C can help stave off or shorten the duration of colds is universal; what is less well-known is that the mineral zinc is also essential to help fight colds and provide a boost to a flagging immune system.

Vitamin C is a well-known antioxidant, which helps keep damaging free radicals that damage cells and contribute to ageing at bay. In normal health it also helps keep the body tissues healthy, and assists with the absorption of iron, another essential mineral.

More zinc is found in the human body than any other trace element except iron, and is mostly located in bone, muscle, the prostate (in men) and the retina. It acts as a vital component in the production of enzymes, can speed up wound healing, and plays an important part in the immune and reproductive systems.

Men with prostate and infertility problems are often found to be lacking in zinc and may need supplements.

The average diet quite often provides less than the Recommended Daily Allowance of 15mgs zinc, especially in vegetarians. Good food sources of zinc include meat, oysters, eggs, seafood, tofu, black-eyed peas and wheat germ.

Elderly people, anyone on a restricted diet, and pregnant or lactating mothers can all benefit from zinc supplements.
