Nutrition and Supplements Amino acids Solgar L-Glutamine 500 mg Vegetable Capsules 50 L-glutamine is the most abundant amino acid and is found in high amounts in muscles. In fact, about 60% of the total amount of muscle amino acids is glutamine. It's classified as a nonessential amino acid (meaning it can be produced by the body), but since it serves as fuel for muscles, in certain situations the demand for glutamine increases and the body is unable to produce enough. For example, during intense exercise, glutamine stores are depleted because the body is under stress, and muscles and tendons need more of this amino acid. In this case, to reduce muscle breakdown, it is necessary to obtain glutamine through the diet. Natural sources of glutamine include beef, fish, cottage cheese, asparagus, and broccoli. Solgar L-Glutamine 500 mg Vegetable Capsules are kosher and suitable for vegans and vegetarians. The dose of 1 capsule per day provides the body with 500 mg of L-glutamine.
