"The B vitamins help maintain the health of nerves, skin, eyes, hair, liver, and mouth, as well as a healthy muscle tone in the gastrointestinal tract and proper brain function. B-complex vitamins act as coenzymes, helping enzymes to react chemically with other substances, and are involved in energy production. They may be useful for alleviating depression or anxiety as well. Adequate intake of the B vitamins is very important for elderly people because these nutrients are not as well absorbed as we age. There have even been cases of people diagnosed with Alzheimer’s disease whose problems were later found to to be due to a deficiency of vitamin B12 plus the B complex."
