But what exactly are dietary supplements, and which ones are truly beneficial? This extensive guide takes a deep dive into the world of dietary supplements, offering a comprehensive list of the most popular types, their benefits, and considerations to keep in mind when incorporating them into your routine.
What Are Dietary Supplements?
Dietary supplements are products designed to augment your daily intake of nutrients, including vitamins, minerals, amino acids, enzymes, herbs, and other botanicals. They come in many forms - capsules, powders, gummies, liquids - and aim to provide essential nutrients that may be missing or deficient in your diet. While supplements can provide great health benefits, it is important to remember that they are not a substitute for a healthy diet. They are meant to complement—not replace—the nutrients obtained from food.
