Sport supplements are nutritional products that are taken by mouth and have the objective of complementing (never substituting) your usual nutrition. They are products that are used to improve sport performance, made with ingredients such as proteins, amino acids, vitamins, minerals and plant extracts, among others. They usually come alone or in combination with others in order to increase efficiency. Depending on the sport supplement, they can come in powders, tablets, capsules, bars, gels or liquid. All nutritional supplements are regulated by law and must be correctly labeled in accordance with the valid regulations.
