Vadim Nemkov reveals kidney issues caused conditioning problems against Anderson

Vadim Nemkov disclosed that kidney problems in 2022 caused severe conditioning issues that affected his performance against Corey Anderson. He experienced dramatic fatigue after just one round in sparring sessions, unable to maintain output beyond the opening frame. Medical testing eventually identified kidney issues related to severe weight cuts as the root cause. Nemkov found an approved pharmaceutical solution during a training camp in Thailand before the rematch, which restored his health. Since discovering the problem, he has completely eliminated all sports supplements including creatine, protein, and BCAAs from his regimen due to the strain they place on kidneys. He now only takes vitamins including omega-3, fish oil, magnesium, and vitamin B, and reports feeling no worse without the supplements as long as his nutrition, sleep, and vitamin intake are properly managed.
