The Pros and Cons of Taking Dietary Supplements

Dietary supplements are increasingly popular, with millions of Americans taking them to improve their health and well-being. These supplements come in various forms, including vitamins, minerals, herbs, and powders, and are marketed as a way to support your overall health and fill nutritional gaps in your diet. While dietary supplements can be beneficial, they come with some potential drawbacks as well. In this article, we will explore the pros and cons of taking dietary supplements.

Many people don’t consume enough of certain nutrients in their diet, such as vitamin D, calcium, magnesium, or iron. Supplements can help ensure you get enough of these important nutrients to meet your body’s needs.
