Product Details

What is L-Glutamine Alpha-Ketoglutarate (AKG)?

L-glutamine alpha-ketoglutarate (AKG) provides the non-essential amino acid, L-glutamine, along with alpha-ketoglutaric acid, a component of the Citric Acid Cycle.

What is L-Glutamine?

L-glutamine is the most abundant of the 20 non-essential amino acids. It is a large component of protein in skeletal muscle tissue and occurs in high concentrations in the brain, intestinal lining, lungs, heart, kidney, and liver.

Glutamine can become a conditionally essential amino acid for some individuals. Vegans and vegetarians may not produce enough glutamine as they do not consume many glutamine dietary sources. For example, whey protein and casein are the best glutamine food sources, but they come from dairy products.

What is Alpha-Ketoglutarate (AKG)?

Alpha-ketoglutarate (α-Ketoglutarate or AKG) is a keto acid produced by de-amination of the amino acid glutamate. It is a metabolic intermediate in the Citric Acid Cycle that produces cellular energy. Alpha-ketoglutarate is critical for nitrogen metabolism and transporting nitrogen to the liver, where the urea cycle takes place. As a nitrogen scavenger, AKG can inhibit toxic ammonia buildup.

It also has antioxidant properties. AKG helps reduce hydrogen peroxide levels, which inhibits the formation of hydroxyl free radicals. It also helps reduce oxidative stress. Free radicals and oxidative stress both damage cell health, contribute to the onset and progression of many illnesses, and speed up the aging process.

Potential L-Glutamine Alpha-Ketoglutarate (AKG) Supplement Benefits

Athletes and individuals performing intense strength training workouts may benefit from supplemental glutamine. The body requires more glutamine during resistance training, and its demand for glutamine may surpass its ability to synthesize it. Glutamine may also act as a cellular energy source, reduce muscle soreness, and speed up recovery after exercise. Glutamine is a component of protein synthesis, which may further benefit muscles.

AKG may support glutamine’s effects on exercise performance. AKG stimulates protein synthesis while inhibiting protein breakdown. Animal studies showed it facilitated weight loss by influencing microbiota in the gut. AKG is also a precursor to glutamate, which the body uses to synthesize more glutamine.

Potential L-Glutamine Alpha-Ketoglutarate (AKG) Supplement Side Effects

Most individuals tolerate l-glutamine AKG well. As a naturally occurring amino acid, glutamine does not typically cause side effects. Some individuals may experience stomach discomfort.
