Introduction
Weight loss supplements encompass a wide range of products, including pills, powders, and liquids, each claiming to help shed pounds quickly and effectively. These supplements often promise to boost metabolism, reduce appetite, block fat absorption, or enhance fat burning. However, the reality is that not all supplements are created equal, and their effectiveness can vary widely.
