Glutamine is one of the body’s most abundant amino acids and is the building block for all essential proteins. It is most commonly used to boost the immune system to combat the effects of bodily distress. Glutamine also enhances exercise performance and expedites muscle recovery allowing its users to effectively burn more calories.


Arginine is an amino acid that converts into nitric oxide. Nitric oxide is a neurotransmitter that improves circulation and blood flow. Due to arginine’s positive effects on blood circulation, workout performance and muscle recovery time has been shown to improve while taking arginine,


Carnitine is a substance produced by the liver and kidneys which converts body fat into energy. Think of it as a car, “driving” fat into the cell to be burned. Studies show that carnitine reduces body fat, increases muscle mass, improves stamina and strength and lessens fatigue, which may all contribute to weight loss. Its muscle building properties make it a favorite among weightlifters and bodybuilding professionals. Carnitine has also been used to boost energy during times of caloric deficit which can help to eliminate fatigue and irritability while dieting.
