The effect of popular sports supplements with arginine alpha-ketoglutarate (AAKG) is no higher than placebo, say scientists from the University of Baylor, according to an online edition for girls and women from 14 to 35 years old Pannochka. Net Scientists conducted an experiment with volunteers. 24 athletes during the week took supplements NO2 Platinum with arginine alpha-ketoglutarate. Scientists have measured the arterial blood flow on their hands after weight training. The results of the studies showed that the administration of AAKG did not lead to an increase in blood flow.

- Small changes were, however, they came from the fact that people were pumping iron. Tablets did not have any effect. This disproves the claim of manufacturers of sports nutrition that "vasodilator supplements" are an effective means of leading vasodilation, accelerating blood flow to the skeletal muscles during weight training. In addition, we specifically showed that strength training increases vasodilation, arterial blood flow and nitric oxide level. And the effect of additives with arginine alpha-ketoglutarate is no higher than placebo, "said the author of the study, Derrin Wilouby, post-graduate student of biochemistry of nutrition and molecular physiology.

Arginine alpha-ketoglutarate (AAKG) should increase the production of nitric oxide (NO), which supposedly leads to vasodilation and an increase in blood flow to the muscles. The intake of dietary supplements based on AAKG during training with weights should lead to an increase in strength indicators.

The study was published on Wednesday at the university's official website. It is accepted for publication in the medical journal on sports nutrition International Journal of Sport Nutrition and Exercise Metabolism.
