In this module, we will discuss the core topics related to nutrition and speak about supplementation. We shall define the term ‘supplements’ and give an overview of the two different categories that we will refer to throughout this module; the distinction between them is important because different people think of different things when the word ‘supplement’ is used.
We will then go in to some broad contexts that may warrant supplement use before taking you through the mechanisms by which certain key supplements perform the role that they do. Finally, we will round this module off by providing you with a means for ascertaining the efficacy of any supplement you come across. This final point is incredibly important because, as you will see, not all supplements and not all supplement claims are produced with the same degree of integrity.
