Vadim Nemkov reveals kidney issues caused stamina problems in Corey Anderson fights

Vadim Nemkov disclosed that he suffered from kidney problems in 2022 that severely impacted his performance against Corey Anderson. The issues caused him to fatigue rapidly after the first round in both sparring and competition. After the first Anderson fight, medical testing revealed the kidney problem, and doctors found an appropriate pharmaceutical solution. Nemkov has since eliminated all sports supplements from his diet, including creatine, protein, and BCAAs, due to the strain they place on his kidneys. He now only takes vitamins including omega-3, fish oil, magnesium, and B vitamins. Nemkov reported that removing supplements has not negatively affected his performance.
