A "supplement" by definition is something you would take in addition to whatever you would eat or drink in the course of your normal diet. Examples of supplements can range from commonly used and safe substances such as multivitamins, to generally safe performance improving substances such as creatine, and then to unsafe items such as ephedrine and pseudoephedrine.
