3.3. Health Claims Associated with Dietary Supplements
Health claims are statements used on dietary supplement labels or advertisements to describe the relationship between a product and its potential health benefits. These claims influence consumer perception and play an important role in product marketing. However, improper or scientifically unsupported claims may mislead consumers and create significant public health concerns. Therefore, health claims should be supported by reliable scientific evidence and regulated by appropriate authorities.[5]
3.3.1 Definition of Health Claims
Health claims refer to statements suggesting that a dietary supplement or one of its ingredients may provide specific health benefits, support normal body functions, or reduce the risk of certain diseases. These claims are intended to inform consumers about the physiological or nutritional role of a product.[6]
3.3.2 Categories of Health Claims
Nutrient Content Claims
These claims describe the level of a nutrient present in a product, such as “high in vitamin C” or “low fat.”
Functional Claims
Functional claims indicate the role of a nutrient or ingredient in maintaining normal physiological functions, such as supporting immunity or energy production.
Structure/Function Claims
These claims describe the effect of a product on the normal structure or function of the human body, for example, “supports bone health” or “helps maintain joint flexibility.”
Disease Risk Reduction Claims
These claims suggest that consumption of a product may reduce the risk of developing a specific disease or health condition when supported by scientific evidence.[6]
3.3.3 Scientific Evidence Required for Health Claims
Health claims associated with dietary supplements should be supported by adequate scientific evidence to ensure accuracy and consumer safety.
