Losing weight can be tough, especially when you’ve already tried dieting, exercise, and cutting calories. If you feel like you’re doing everything right and still not seeing results, you’re not alone. Many people turn to weight loss supplements for that extra push. But do they actually work?
The good news is, some do. There are weight loss supplements backed by clinical research and trusted by nutritionists and health professionals. These supplements can help boost metabolism, reduce appetite, or support fat breakdown—when used alongside a balanced diet and regular exercise.
Let’s break down the top 5 weight loss supplements that actually work, according to experts.
Garcinia Cambogia Extract
Garcinia Cambogia is a tropical fruit that contains hydroxycitric acid (HCA). According to a meta-analysis published in the International Journal of Clinical Practice, HCA may help suppress appetite and inhibit fat production.
What It Does:
- Suppresses appetite
- May block fat production
- May help reduce belly fat
Top Pick: Horbäach Garcinia Cambogia Extract Supplements— Horbäach Garcinia Cambogia Extract Supplements offer a concentrated source of HCA, potentially aiding weight management by supporting appetite control and influencing fat production. While derived from a natural source and potentially helpful in complementing a healthy lifestyle, scientific evidence on significant weight loss is mixed, and mild side effects or interactions are possible. It’s best used alongside diet and exercise, and consulting a healthcare professional is advised before use.
Things to Know: Garcinia Cambogia works best when paired with a low-calorie diet. Look for supplements that contain 50–60% HCA and avoid products with unnecessary additives.
Green Tea Extract
Green tea extract is rich in antioxidants and catechins, especially EGCG (epigallocatechin gallate). EGCG helps enhance fat oxidation and increases energy expenditure. Studies published in The Cochrane database of systematic reviews have shown green tea extract may aid in weight loss by boosting metabolism.
What It Does:
- Increases metabolism
- Helps burn fat (especially during exercise)
- Provides antioxidant support
Top Pick: NOW Supplements Green Tea Extract – NOW Green Tea Extract Supplements provide a concentrated source of beneficial plant compounds, primarily catechins like EGCG, known for their antioxidant properties. This supplement is often used to support overall health and well-being, potentially contributing to cardiovascular health, weight management, and cellular protection against oxidative stress. While generally well-tolerated, high doses may cause side effects, and it can interact with certain medications. It’s typically viewed as a supportive addition to a healthy lifestyle rather than a standalone treatment, and consulting a healthcare professional is recommended.
Things to Know: Choose a green tea extract that contains at least 45% EGCG. Avoid products with excessive caffeine if you’re sensitive.
