Vadim Nemkov reveals kidney issues caused gas tank problems in Corey Anderson loss

Vadim Nemkov disclosed that kidney problems in 2022 caused severe cardio issues leading to his first loss to Corey Anderson. He would gas out after one round in sparring despite feeling fine in other training. Medical tests eventually identified kidney issues related to extreme weight cuts as the cause. After finding the problem and proper medication during a training camp in Thailand before the rematch, his conditioning returned to normal. Nemkov also revealed he has completely eliminated sports supplements like creatine, protein, and BCAAs from his diet due to the kidney strain they cause, now only taking basic vitamins. He stated he doesn't feel worse without supplements as long as his nutrition, sleep, and vitamin intake are properly managed.
