The Problem With Supplements

Dr Glenn McConell chats with Professor Mark Tarnopolsky from McMaster University in Canada. Mark has done pioneering studies in many areas including sex differences and exercise, HITT training and creatine supplementation. Today we focus on his remarkable work with muscle myopathies. Exercise can be beneficial in all muscle myopathies in regards to function and/or healthspan and/or lifespan. The type of exercise will differ depending on the myopathy: endurance, resistance, or both.
