Ornithine alpha-ketoglutarate (OKG) is a salt formed of two molecules of ornithine and one molecule of alfa-ketoglutarate. Studies in the medical field have shown that ornithine alpha-ketoglutarate preserve muscle protein synthesis and spares nitrogen after elective surgery. OKG treatment decreases muscle protein catabolism and/or increases synthesis, according to the metabolic situation. The anti-catabolic effect might not be from OKG alone. OKG increases the plasma concentrations of, for example, arginine, leucine, isoleucine, tyrosine, glutamine, proline and ornithine. There are several studies that show these amino acids to have anabolic properties; hence, the anti-catabolic effect. As far as we know there haven’t been any studies on athletes and OKG, we have to relate to the medical studies. The most interesting aspect of OKG is that it helps to increase the levels of glutamine in the muscle cells. As we know, high glutamine levels have a very anti-catabolic effect, especially in people under severe stress such as hard training or fasten.

Some studies have shown OKG to have positive effects on the immune system, this due to the increased amount of arginine in the blood stream.

As with all supplements, the dosage varies depending on your weight (muscle mass), activity level and food intake. Take one half about an hour before training and the second half before bedtime.

You can take your OKG together with carbohydrates. No side effects have been reported from OKG supplementation when taken in recommended dosages. Higher dosages might cause stomach problems such as diarrhea. OKG seems to be a good supplement for athletes during hard training and/or diet.


Take 1 tablet 3 times a day with water, the first in the morning, the second immediately after training, and the last one before bedtime. Do not chew the product.
