A vitamin/mineral supplement has this claim on the label: "Boosts immunity." What type of claim is this?

Structure/function claims.

Explanation:

Vitamin may be defined as the chemicals that are required in the diet in the small amounts and their deficiency might cause a disease in humans. Two types of vitamin are fat soluble vitamin and water soluble vitamin.

The supplements are given to complete the nutrition deficiency in the body. The functional or structural claims determine the special characteristics of that chemical. The specific functional of a particular vitamin is involved in the functional claims.

Thus, the correct answer is structure/function claims.
