A dietary supplement is a product that contains vitamins, minerals, herbs, or other substances that are intended to supplement a person's diet. However, there are many other names that are used to describe these products. Some synonyms for dietary supplements include nutritional supplements, food supplements, health supplements, natural supplements, and vitamin supplements. Additionally, some people may refer to these products as energy boosters, mood enhancers, or even performance enhancers. Regardless of what they are called, dietary supplements can play a valuable role in maintaining optimal health and nutrition. However, it's important to remember that dietary supplements are not a substitute for a healthy diet and regular exercise.
