A dietary supplement is a product taken by mouth that contains a “dietary ingredient” intended to supplement the diet. Ingredients may include vitamins, minerals, herbs, other botanicals, amino acids, and substances like enzymes, organ tissues, glandulars, and metabolites. Supplements may be found in different forms, like extracts, concentrates, tablets, capsules, softgels, gelcaps, liquids, bars, or powders. Information on these packaging labels must not represent the product as a conventional food or a sole item of a meal or diet.
It is important to note that the disease progression and the severity of symptoms vary in each person. Some children may experience a mild, short-term disease, whereas others experience a severe, long-term condition.
