Vitamin B Helps Your Metabolism. You should balance your vitamin supplements to match your needs. A multi-vitamin is great, but if you are extremely fatigued all the time and don't get enough vitamin B in your diet, then adding vitamin B-12 will improve your flagging energy. B-complex vitamins provide you with: 1  Boosted metabolism. 2  Healthy skin.
There are certain foods which help speed up your metabolism by either: 1  Increasing muscle mass with complete protein dense foods. 2  Stabilizing the bad hormones (insulin and cortisol) which accelerates fat storage. 3  Keeping you full longer to help reduce cravings.
