Vadim Nemkov reveals kidney issues caused cardio problems in Corey Anderson loss

Vadim Nemkov disclosed that he suffered from kidney problems in 2022 that severely affected his cardio, causing him to fade after one round in sparring and in his first fight against Corey Anderson. Despite performing well in other training like CrossFit and weight training, he would run out of energy in the second round of sparring sessions. After extensive medical consultation and testing in Thailand, doctors identified the kidney issue and prescribed a legal, over-the-counter medication that resolved the problem. Nemkov also revealed he has eliminated all sports supplements from his diet due to the strain they place on his kidneys, now only taking basic vitamins including omega-3, fish oil, magnesium, and B vitamins. He stated that removing supplements like creatine, protein, and BCAAs hasn't negatively impacted his performance.
