What Is a Nutritional Supplement: A Science-Based Guide
A nutritional supplement is a product designed to complement the diet by providing nutrients such as vitamins, minerals, or functional compounds that support normal bodily functions. In the U.S., supplements are regulated as foods, not drugs, and are intended to fill nutritional gaps rather than replace meals or treat disease. Their usefulness depends on individual needs, lifestyle factors, and responsible use.
What Is a Food Supplement: A Science-Based Guide
A food supplement is a concentrated source of nutrients—such as vitamins, minerals, amino acids, electrolytes, or protein—designed to support the normal diet, not replace food. Supplements help fill nutritional gaps caused by lifestyle, training, or increased physiological demand. They are regulated as foods, not drugs, and should be used with proper dosing, quality verification, and realistic expectations.
