Weight loss supplements are products designed to support weight loss by various mechanisms, such as increasing metabolism, reducing appetite, or enhancing fat burning. It's important to note that the effectiveness and safety of these supplements can vary widely, and not all of them are backed by rigorous scientific evidence. Before using any weight loss supplement, it's essential to consult with a healthcare professional, as some of these products may have side effects or interact with other medications you might be taking.
Here are some common types of weight loss supplements and their associated ingredients:
Appetite Suppressants: These supplements work by reducing your appetite, leading to a decreased calorie intake.
- Garcinia Cambogia: Derived from a tropical fruit, some studies suggest it may help suppress appetite.
