Intake of a vitamin pill on a daily basis may help to boost
memory and slow mental decline.
According to new studies, taking supplements has a beneficial effect on memory and may work by increasing the efficiency of brain cells.
One study showed that after just four weeks there were measurable changes in electrical activity in the brain when carrying out memory tests.
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 Centre 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."
