Question

select the correct answer.
which is the best definition of a dietary supplement?
a substance that enhances health by adding synthetic forms of nutrients to the diet
a pill, liquid or powder that is not a food item and contain some nutrients
a synthetic substance that is chemically similar to the hormone testosterone

Explanation:

A dietary supplement is defined as a product (other than tobacco) intended to supplement the diet that bears or contains one or more of the following dietary ingredients: a vitamin, a mineral, an herb or other botanical, an amino acid, a dietary substance for use by man to supplement the diet by increasing the total dietary intake, or a concentrate, metabolite, constituent, extract, or combination of any of the aforementioned ingredients. It can come in forms like pills, liquids, or powders and is not a traditional food item but contains nutrients. The first option is too narrow as it only mentions synthetic forms (dietary supplements can have natural nutrients too). The third option is incorrect as it describes a specific type of synthetic substance (similar to testosterone) which is not the general definition of a dietary supplement.

Answer:

a pill, liquid or powder that is not a food item and contain some nutrients
