A daily multivitamin tablet may boost the memory and slow mental decline, the Daily Mail reported Sunday.
The body needs 13 vitamins to function properly and maintain health. Vitamins A, C, D, E and K and the eight B vitamins each have specific job in the body. Vitamin C keeps cells healthy, D regulates calcium and E maintains cell structure, while the B vitamins, including folic acid, have a wide range of functions. David Kennedy, of the Brain, Performance and Nutrition Research Center at Northumbria University, said: "The evidence is still limited but the studies hint at some possible beneficial effects. "Optimal brain function depends on an adequate level of all of the vitamins."
