Restraints in the Nutritional Immunology Market

The Nutritional Immunology market faces significant constraints due to various factors. While vitamins and supplements can help mitigate nutritional deficiencies, obtaining these essential nutrients directly from food remains the most effective approach. Certain supplements may lead to adverse side effects, particularly when used prior to surgery or alongside other medications, posing risks for individuals with specific health conditions. Additionally, the effects of many supplements on vulnerable groups, such as children and pregnant women, remain largely unexamined. As these products are classified as foods rather than pharmaceuticals, they lack rigorous FDA scrutiny and clear labeling of potential side effects, further endangering the older population and inhibiting market growth.
