What term is used for a product taken by mouth that is intended to supplement the diet, with advice to maintain a balanced diet?

• A. Drug
• B. Dietary supplement
• C. Composition
• D. Displacement

Answer: (B)

A product taken by mouth to fill gaps in the diet is called a dietary supplement. This term fits because it covers vitamins, minerals, herbs, amino acids, and similar substances taken in forms like pills or powders, with guidance to maintain a balanced diet rather than replace meals. A drug, by contrast, is aimed at treating or preventing disease and typically requires medical supervision. Composition and displacement are unrelated terms in this context.
