Dietary supplements are products that are intended to supplement the diet with additional nutrients such as vitamins, minerals, amino acids, herbs, or other botanicals. These products come in various forms including pills, capsules, powders, and liquids, and are marketed as a way to help maintain or improve health. Research in the area of dietary supplements focuses on evaluating the efficacy, safety, and potential health benefits of these products. Studies may investigate the effects of specific nutrients on various health conditions, explore the interactions between different supplements and medications, or examine the overall impact of dietary supplements on dietary patterns and health outcomes. Researchers also study consumer attitudes and behavior towards dietary supplements, as well as the regulatory policies and guidelines that govern their sale and marketing. Overall, the goal of research in this area is to provide evidence-based information to help individuals make informed decisions about the use of dietary supplements for promoting health and well-being.
