¹A nutrient naturally built into the body's chemistry

Best Carnitine Energy supplies L-carnitine, an amino acid nutrient vital for converting fats into energy, and to metabolize carbohydrates. Carnitine protects and facilitates the mitochondria's essential energy functions, but can be depleted by common lifestyle factors and advancing age. Best Carnitine Energy provides this conditionally essential nutrient at high potency for youthful wellbeing and healthy aging.

The sigma-tau L-Carnitine in this product is derived from a base of pharmaceutical grade L-Carnitine manufactured by a patented, FDA-approved process. It is GMO-free, pesticide-free, and BSE free.

  • Vital for energy production by mitochondria.
  • Promotes fat and carbohydrate metabolism.
  • Elevates resistance to oxidative stress.
  • Enhances brain, circulatory & other organ functions.
