There is great interest in anything people might do to keep themselves mentally healthy as they age and, especially, to reduce their risk of developing dementia. Various vitamin and mineral supplements have been suggested as ways to do this. Vitamins and minerals have many functions in the body and the ways they might affect brain health are not well understood. Therefore, we were interested in the effects of any vitamins or minerals, either alone or in combination. This review focusses on the effect of vitamins or minerals (or both) on cognitive functioning. Vitamins are organic compounds that are essential for the normal physiological process in the body and play important roles in growth and development . Minerals are inorganic elements and as nutrients are also needed by the body to grow and develop normally. Most of these essential nutrients are available naturally in the diet. Dietary supplements are any consumed products that aim to provide nutrients additional to those obtained in the regular diet.
