VITAMIN B6
Adults between 19 and 50 should aim to get 1.4 milligrams of vitamin B6 from baked potatoes, bananas, and chickpeas daily. After age 50, men should aim for 1.5 milligrams, while females should get 1.5 milligrams. Some use it to prevent mental decline and lower levels of homocysteine (an amino acid associated with heart disease), but the studies are mixed. Two studies failed to show cognitive benefits, and while B6 does reduce homocysteine, it’s not clear whether this prevents heart attacks.
