Glutamine Alpha Ketoglutarate

Also known as: Glutamine AKG, Glutamine Alpha-Ketoglutarate

Overview

Glutamine Alpha-Ketoglutarate (AKG) is a compound formed by the combination of the amino acid glutamine and the metabolic intermediate alpha-ketoglutarate, which is integral to the Krebs cycle. This compound is naturally produced in the body and can also be sourced from dietary intake, particularly from protein-rich foods such as meat and certain vegetables. It is primarily used as a nutritional supplement to promote gut health, support immune function, and aid in muscle recovery following exertion. Research on AKG demonstrates variable quality but suggests it may enhance gut morphology, reduce inflammation, and support muscle synthesis, highlighting its relevance in both health and athletic performance.

Benefits

Clinical evidence surrounding Glutamine Alpha-Ketoglutarate suggests several benefits. AKG supplementation has been shown to improve gut morphology and function, particularly in conjunction with ornithine. Additionally, glutamine supplementation has been associated with weight reduction, making it potentially beneficial for individuals requiring weight management. More broadly, AKG may assist in reducing systemic inflammation and support muscle protein synthesis. These effects are particularly relevant for populations undergoing surgery or those experiencing muscle wasting. However, while some studies show promising results regarding gut health and muscle recovery, the findings are mixed and further research is warranted to quantify these benefits accurately.

How it works

Glutamine Alpha-Ketoglutarate primarily exerts its effects via its involvement in the Krebs cycle, facilitating energy metabolism and influencing glutamine metabolism in the body. Glutamine plays a crucial role in maintaining gut barrier integrity and supporting immune function. In addition, AKG is known to interact with signaling pathways related to energy metabolism and the stress response, enhancing overall cellular function and resilience in various tissues, most notably in the gastrointestinal and muscular systems.

Side effects

Glutamine Alpha-Ketoglutarate is generally considered safe when used according to recommended guidelines, but some individuals may experience gastrointestinal upset as a common side effect (occurring in more than 5% of users). Uncommon and rare side effects are not well-documented, but caution is advised for people with severe kidney or liver disease. Drug interactions could occur with medications that impact gut health or metabolism, so users should monitor for any adverse reactions. Older adults may particularly benefit from supplementation due to decreased natural production of AKG, yet they should approach use with awareness of their health status.

Dosage

While the minimum effective dosage for Glutamine Alpha-Ketoglutarate has not been clearly established, suggested ranges typically lie between 1 to 5 grams per day. An optimal dosage may be enhanced when combined with ornithine. It is generally considered safe to use up to 10 grams per day, though higher amounts should be approached cautiously. For best results, it is advised to take AKG with meals to improve absorption. Oral supplements are common, while intravenous forms may be applicable in clinical contexts. Factors such as the presence of other nutrients can influence absorption rates.
