VITAMIN B12
Vitamin B12-rich foods include fish and shellfish, lean beef, and fortified breakfast cereal; it’s a vitamin vegetarians and vegans tend to be low in. Aim to get 2.4 micrograms from those sources every day. Vitamin B12 deficiency, which can cause anemia and dementia, is a problem for some seniors, so supplements can help. However, high doses of B12 have not been proven to prevent cognitive loss, and they don’t boost energy.
