Substances that Affect Energy Metabolism
- Coenzyme Q10 (CoQ10)
- B vitamins, like vitamin B6, vitamin B12, folic acid, thiamine, niacin
- Creatine, carnitine, and amino acids like tyrosine, phenylalanine, taurine
Many energy supplements are derived from the nutrients, proteins, fats, and amino acids that are already in our bodies or that we get from food. And they do work — in a sense. “Research has clearly shown that these compounds support the energy metabolism process,” says Shao. They affect how the body processes the nutrients we eat and converts them into energy.
People who are deficient in CoQ10, carnitine, and B vitamins may benefit from the supplements, says David Leopold, MD, director of Integrative Medical Education at the Scripps Center for Integrative Medicine. “And deficiency is much more common than we think,” he notes.
