Eating healthful foods, reducing calorie intake, and staying physically active are proven ways to lose weight. However, making these lifestyle changes can be challenging. Some people choose dietary supplements that may support weight loss by blocking the absorption of fat or carbohydrates, curbing appetite, or boosting metabolism.
Weight-loss supplements contain many ingredients—such as herbs, fiber, and minerals—in varying amounts and combinations. They are sold as capsules, tablets, liquids, and powders, and some products contain dozens of ingredients.
Common ingredients found in weight-loss supplements are listed below in alphabetical order. You’ll learn what is known about whether each ingredient is effective and safe. Determining how well these ingredients work for weight loss can be complex, especially since most products contain multiple ingredients that may interact differently when combined.
Supplements are often designed to burn fat, increase metabolism, and boost energy levels. Appetite suppressants may help reduce hunger and help you feel full sooner, which can support short-term weight loss.
