Nemkov reveals kidney issues caused cardio problems in Corey Anderson loss

Vadim Nemkov disclosed that he had kidney problems in 2022 that caused severe cardio issues, particularly affecting his performance in sparring and in his first fight against Corey Anderson. He would perform well in the first round but completely run out of gas in the second, feeling like someone had "cut off the fuel." After consulting with his doctor and traveling to Thailand for a training camp in August before the rematch, he found the cause and a legal medication that resolved the issue, which he continues to use. Nemkov has since eliminated all sports supplements from his diet, including creatine, protein, and BCAAs, as they place stress on the kidneys. He now only takes vitamins including omega-3, fish oil, magnesium, and B vitamins, and says he doesn't feel worse without the supplements as long as he maintains proper nutrition and sleep.
