Glutamine, arginine and carnitine are a trio of amino acids (the building blocks of protein) known to help reduce inflammation in joints, connective tissue and muscle. Delivered in injectable form, this “triple treat” (for optimal health!) provides more efficacy than when taken orally, where absorption may be hindered by intestinal barriers or other conditions.
As the most abundant amino acid in the human body, Glutamine is said to boost exercise performance and expedite recovery from the same, and it may cause higher growth hormone levels. It is known to help ensure that valuable muscle tissue will not be burned during the weight loss process. Glutamine levels may be decreased during concentrated exercise, taking as many as six days to be replenished on their own (without supplementation).
One study noted it can reduce cravings for alcohol and sugar, and counteract the storage of dietary fats by converting energy stores to glycogen instead of fat, making it more accessible for rapid use.
Arginine is an amino acid that converts into nitric oxide—a vasodilator that propels blood flow to muscles and organs. Like glutamine, exercise performance and recovery time are enhanced. Arginine can also boost growth hormone levels, and has also been shown to improve sexual performance through vasodilatation. It can be found in red meat, poultry, fish, dairy, wheat, cabbage, beans, beets, spinach and parsley, and is used medicinally for conditions like congestive heart failure, hypertension and coronary artery disease.
Carnitine, a transport substance for fatty acids produced by the liver and kidneys and stored in the skeletal muscles, heart and brain, is often used to treat heart and circulatory disorders, ADHD, Lyme disease and hyperactive thyroid conditions. Reportedly 70 percent of the metabolic energy required by the heart is supplied by fatty acids. In studies carnitine levels have been cited to be responsible for changes in mood and memory, especially as we age.
It also helps the body turn fat into energy, as well as aids in fat loss and improves strength and stamina. Carnitine accelerates muscle building and is subsequently a favorite of body builders. Carnitine increases androgen receptor density resulting in testosterone and other androgens working more efficiently. It is believed to work to rid the body of toxins as a potent anti-oxidant. Carnitine has been used to boost energy in the course of reduction in calorie intake which may leave one weak during dieting.
Combined as an injectable cocktail, glutamine, arginine and carnitine (GAC) is an amino acid trio that stimulates fat metabolism by facilitating the transfer of fatty acids to the mitochondria, called “the power houses of the cells.” This action aids in weight loss and athletic performance (often injected post-workout if that is the goal). GAC has also been used to help expedite repair of workout-related injuries, including torn pectorals, bone spurs and rotator cuff injuries. Some studies have found that GAC injections may help boost the immune system, fortifying against viral and bacterial infections or providing for faster recovery.
