Vitamin B12 is often overlooked. Needed to make blood cells and improve cognition, vitamin B12 gets into the body along with animal proteins like eggs or meat. Most young people who aren’t vegetarians easily get it in their diet. But for the body to use B12, it needs to dissolve it away from the protein. This gets more challenging with age, as the body’s level of stomach acid decreases. B12 not bound to protein is found in fortified cereal and supplements and is more readily absorbed by the body. Starting at age 50, you should get most vitamin B12 from these types of fortified foods.
