Function Claims

Broadly defined, function claims are claims about the specific beneficial effects that the consumption of a food or a constituent of a food (i.e. nutrient or other component) has on normal functions or biological activities of the body. Such claims relate to a positive contribution to health and to the maintenance of a physiological function or to physical or mental performance. Claims of this type must be clearly distinguishable from claims about disease risk reduction or therapeutic effects.

Nutrient function claims, formerly known as biological role claims, are a subset of function claims that describe the well-established roles of energy or known nutrients that are essential for the maintenance of good health or for normal growth and development. An example of a nutrient function claim is "Vitamin A aids in the development and maintenance of night vision".
