Some biologically active additives (dietary supplements) contain hormones and prohibited substances. Doctor and TV presenter Alexander Myasnikov said this on the air of the Russia 1 TV channel. According to the specialist, his friend tried to lose weight with the help of pills, but felt that something was wrong with them. After laboratory research, it turned out that the dietary supplements used contained a powerful narcotic substance. “It's good that he paid attention. Everything could have ended with a cerebrovascular accident or a heart attack,” Myasnikov said. He urged to be careful with dietary supplements. Another friend of his took supplements to improve potency. And although the effect was, the person complained of yellow circles around the eyes. Laboratory analysis has shown the presence of an erectile dysfunction drug in the pills, which, in combination with the nitroglycerin taken, can be deadly. Starting from April 2020, the popularity of dietary supplements and drugs for weight loss began to gradually decline compared to the same period in 2019.
