A nonessential amino acid that plays a major role in protein synthesis, L-glutamine is instrumental in a diverse range of bodily functions.** L-glutamine supports neurotransmitter function and helps to optimize the entire nervous system.** It plays an important role in supporting healthy immune function, and is used in the synthesis of the immune system’s white blood cells.**
L-glutamine is most famous, however, as a sports nutrition supplement. As the most abundant amino acid in the body, it is most concentrated in the muscles – hinting at its importance to athletes and bodybuilders.**
This amino acid occurs naturally in several food sources, such as cabbage, spinach, cheese, red meat, and poultry. However, because of the speed in which the human body can use L-glutamine, especially following injury or during high-intensity exercise, it can be helpful to take supplements. L-glutamine supplements are available in capsule or tablet form, but are also often found as a powder that can be taken mixed with water or another beverage.
L-glutamine Directions for Use
Before you begin any nutritional supplement plan, make sure to consult with your doctor. When taken in a powdered form that’s dissolved in a beverage, L-glutamine dosage can be anywhere from 2 g to 5 g. Levels of 500 mg to 100 mg in tablet or capsule form are also common.
