Do vitamins strengthen the immune system?
Yes. Good nutritional status is an important defense against illness. Vitamins A, C, E, B6 and beta-carotene, have been shown to be essential to maintaining the immune system. A Canadian study conducted in 1992 demonstrated that the immune status of the elderly could be improved significantly by taking a multivitamin. Participants who took a supplement once a day had 25 fewer days of illness and required less antibiotics than those who did not.
