Eat Vitamin B12 (Cyanocobalamin)

Supplement your diet with B12 and you may find that your mood improves, you sleep better, and you have a newfound knack for remembering where you put your car keys. If you take it with B6 and folate, cyanocobalamin can help lower levels of homocysteine, an amino acid that can cause arterial breakdown. It helps boost metabolism by aiding digestion and nutrient absorption, so remember to add it to your diet by dining on enriched dairy products, beef, poultry, tuna and certain shell fish, beef, oysters, crab, and tuna. Vegetarians may need supplemental vitamins.
