Vitamin and mineral supplementation in patients with diabetes mellitus.

Most patients with diabetes generally do not require routine vitamin and mineral supplementation, just like the rest of the population. However, based on the published medical literature, it would appear that some degree of supplementation with certain vitamins (eg, vitamins C and E) and minerals (eg, magnesium) may be worthwhile and become more commonly recommended in the future. The role of vitamins and minerals in controlling blood glucose levels in the patients with diabetes also is discussed.
