The Best Top 6 Weight Loss Supplements: What Are Diet Supplements?
Diet supplements are products designed to complement your nutrition and support specific health goals—such as fat loss, appetite suppression, or increased metabolic rate. They come in various forms, including capsules, powders, teas, and drinks.
Supplements do not replace diet and exercise. Instead, they are adjuncts meant to enhance results when used correctly.

Red flags to avoid:
