The body needs a minimum amount of vitamins and minerals each day to remain healthy and function properly. A balanced diet normally supplies sufficient vitamins. However, serious disorders can still develop if the diet does not meet your body’s needs. Symptoms of a deficiency in vitamins and minerals usually appear when the lack is already in a relatively advanced level. For instance, people who do not have enough of the vitamins A, B1 and B2 suffer from recurring tiredness, mental or emotiona.
