Vadim Nemkov reveals kidney issues caused stamina problems in first Corey Anderson fight

Vadim Nemkov disclosed that he suffered from kidney problems in 2022 that severely impacted his performance. During training camp, he could only last one round in sparring before completely exhausting, a problem that carried into his first fight with Corey Anderson. Nemkov's medical team eventually identified the issue and found a legal pharmaceutical solution that resolved the problem. As a result, he has eliminated all sports supplements from his regimen, including creatine, protein, and BCAAs, to reduce kidney stress. He now only takes basic vitamins like omega-3, fish oil, magnesium, and vitamin B, and reports feeling no worse without the supplements.
