Vitamins, minerals, and herbal supplements can provide health benefits but also have risks. Vitamins are organic molecules found in food that support metabolic functions and health. Minerals are simple elements that play structural and metabolic roles. Herbals are plant-based products thought to have therapeutic value, but their efficacy is difficult to quantify. While supplements can benefit health when obtained through diet, high supplemental doses may cause toxicity and interact negatively with medications. It is best to consult a health professional when taking supplements.
