There are several different types of vitamin B, but they all do the same thing. These are water-soluble vitamins, which means they can be absorbed and utilized without relying on dietary fat. B vitamins help with cellular metabolism. They assist your body in absorbing the food you eat and using it for energy. These vitamins are also important for the formation of red blood cells, which transport oxygen to the various parts of your body.
You can supplement with vitamin B complexes, or you can obtain them from whole-food proteins like meat, fish, eggs, and leafy green vegetables.
