The majority of scientific and epidemiological evidence supports the beneficial effects of micronutrient supplementation on various aspects of health. However, there have also been reports that some dietary supplements and vitamins can promote the growth of cancer. Given that the popularity and use of nutritional supplements is growing, it is important to conduct a comprehensive evaluation of the efficacy of commercially available nutritional supplements.

Nutritional products on the market vary. Many contain single nutrients, while others contain combinations of vitamins, minerals, plant extracts and other nutritional components. The efficacy of such products will differ, but it is rarely, if at all, explained by manufacturers. Usually the selection of specific ingredients is based on published research conducted on individual vitamin, mineral or other nutritional components, however the biological outcome of the combination may depend on the synergistic or antagonistic interactions of its ingredients, the source of its raw materials, and the dose. Manufacturers of nutritional supplements typically do not invest in scientific micronutrient research, mostly taking care of the technological aspect of the formulations.
