We discuss if you should take supplements and what they do to your body. We often get asked if people should take supplements, and our first answer is to always consider your diet first before adding supplements. If you can naturally get protein in your diet then do that first before buying a supplement. We discuss different kinds of protein: whey protein isolate (WPI), whey protein concentrate (WPC) and casein. How are these proteins made and what is their benefits. We also get into why BCAA's are not beneficial for most people, and how creatine is a cost effective and under-utilised supplement that many people forget about.
