But, because most American adults don’t get optimal levels of all vitamins, multivitamins do have a role to play in maintaining good health. Vitamin B-12 deficiency can contribute to nervous-system disorders including irreversible neuropathy, a condition typified by pain, numbness and weakness in the hands and feet. That is not a big benefit, but given the low cost, safety and ease of taking multivitamins, it seems like a good bargain. People also shouldn’t rely on multivitamins to prevent specific problems like deficiencies of vitamin D or vitamin B-12. We don't need a daily multivitamin, and our health isn't improved by taking one.
