The amino acids ornithine and glutamine are combined to form ornithine
Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 StarsReliable and relatively consistent scientific data showing a substantial health benefit.
2 StarsContradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 StarFor an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Preliminary and controlled studies of people with severe burns and other types of injuries showed that supplementation with 10–30 grams of (OKG) per day significantly improved wound healing and decreased the length of hospital stays. Improved healing from major trauma and surgery has also been demonstrated with oral supplements including several grams per day of glutamine.
(OKG) is formed from the amino acids ornithine and glutamine and is believed to facilitate muscle growth by enhancing the body's release of anabolic hormones. While this effect has been found in studies on hospitalized patients and elderly people, no studies on muscle growth in athletes using OKG have been published.
Optimal levels remain unknown, though 10 grams per day has been used in clinical trials.
Although the amino acids that comprise OKG are present in protein foods such as meat and poultry and fish, the OKG compound is found only in supplements.
A deficiency of OKG has not been reported.
