Now Sports L-Glutamine is a nonprescription fitness supplement that is manufactured by a company called NOW Foods. That manufacturer produces a range of different types of health and wellness products and supplements. In this case, it is meant to help active people, such as those who take part in regular workouts, bodybuilders, and athletes.
The only active ingredient within this product is 5,000 mg of L-Glutamine (Free-Form) . It is based on preliminary studies that have suggested that glutamine can be very helpful to athletic performance and health. Though nothing is considered to be "proven", as of yet, there is a growing body of evidence that is starting to look at this substance in a positive light.
The research, according to NOW Foods, which did not cite its claims, says that during certain stressful situations, the body requires a higher amount of glutamine than it is capable of naturally producing. It is also believed that the levels of this antioxidant gradually decline in the body as a part of aging. When the body's demand for glutamine exceeds its production, it becomes what is known as a "conditionally essential" amino acid.
L-glutamine is a substance that is an integral part of the positive nitrogen balance within the body, also known as the anabolic state. That said, it is also assists in the process of rapid cell growth (particularly in the case of intestinal cell enterocytes and immune system lymphocytes). It is also known to be a nitrogen transporter and is an acid-base balance regulator.
The Now Sports L-Glutamine product is sold in the form of a powder instead of a pill. In this way, 1 rounded teaspoon (5 grams) of the product are added to juice, between meals, once or twice daily, as needed.
While the manufacturer does say that using this product helps to support muscle mass, it is very careful in its description of the product on its official website, never to actually make any specific claims about what a user can expect from having taken it on a regular basis, according to the package directions.
Therefore, it is up to the user to decide how they feel that they would be able to benefit from enhancing the glutamine levels in their body.
For this reason, it is a very good idea to speak with a doctor before starting the use of Now Sports L-Glutamine, to ensure that it is necessary, can be effective, and will be safe for use.
