B-complex vitamins are coenzymes involved in energy production, and may be useful for alleviating depression or anxiety. 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 be due to a deficiency of vitamin B12 plus the B complex.
The B vitamins should always be taken together, but up to two to three times more of one B vitamin than another can be taken for a particular disorder.
