L-Carnitine Summary

All L-Carnitine Supplement Benefits/Effects/Facts & Information

L-Carnitine and Acetyl-L-Carnitine (ALCAR) are considered to be “vitamin-like” supplements that closely relate to B-Vitamins and are compounds known for improving cardiovascular health, reversing the effects of aging, preventing disease, improving depression, and decreasing muscle soreness.

Carnitine offers a host of performance enhancing benefits too.

  • L-Carnitine may help burn fat around stubborn areas like the belly or mid-section.  (Fat in this area is very dangerous to your overall health and well being.)
  • Improves blood flow which allows for better nutrient and oxygen delivery to muscles. (Helps improve recovery and reduce muscle soreness after exercise)
  • Carnitine increases energy and increases the amount of fat burned during physical activity. (More energy increases activity which means more fat burning potential)
  • Carnitine helps your body use the fat you have as energy instead of your muscle glycogen. (deficiency in carnitine means your body doesn’t use fat reserves as fuel, this leads to muscle soreness, weight gain, and muscle weakness)

Carnitine is made in the body but is abundant in foods such as red meat, nuts, grains, and dark green vegetables. Supplementation isn’t  necessary if your diet is amazing, but increasing the amount of carnitine within the body amplifies the benefits. (This is why its a popular fitness/sports supplement)

If you have never tired l-carnitine supplementation for yourself, you may be missing out on a lot of potential benefits. Picture better lifts, more energy, faster recovery, less muscle soreness, more weight loss and a better looking physique.

A healthy diet, lifestyle changes and nutritional supplements are all part of the equation for achieving a great looking body.

Carnitine is often used as an aid for weight loss, to improve exercise performance, and to enhance a sense of well-being.– U.S. Department of Health & Human Services
