Over 30% of elderly people are at risk of developing deficiencies in vitamin B-12, due to the changes occurring in their digestive tract. Combined with the lack of other vitamins, lack of vitamin B-12 contributes to Alzheimer's disease. Early correction of this deficiency is important, and it will help the elderly people to continue with a normal life Giovannucci, 2005.
The correction of this deficiency can only be through prescribed vitamin supplements, as the cause of its deficiency was not because of an unbalanced diet.

Vitamin deficiency has also been associated with poor eye sight, defective teeth, infections, and dry skin. In elderly people, these diseases are heightened, and they are more prone.
