Supplements are products taken orally that contain one or more dietary ingredients such as vitamins, minerals, amino acids, herbs, or other botanicals. These products are intended to supplement the diet and provide additional nutrients that may be lacking in a person's daily intake. Research in this area focuses on the effectiveness and safety of various supplements, their impact on health outcomes, and their potential interactions with medications or other supplements. Studies may also investigate the optimal dosage, form, and timing of supplementation for different health conditions or populations. Overall, research on supplements aims to provide evidence-based recommendations to help individuals make informed decisions about their use.
