A dietary supplement is any product that is intended to augment the diet and that contains a minimum of one of those compounds: vitamins, minerals, herbs or other botanicals, amino acids, as well as substances for example enzymes, metabolites, glandulars, organ tissues, or a mix of these ingredients. Should you decide to bring a dietary supplement, look at supplement label carefully. The label will show just how much of a specific vitamin, botanical, mineral, or other is in every dietary supplement.
