⚠️ Always consult your doctor before starting any supplement, especially if you have underlying health conditions or take prescription meds.
1. Glucomannan (Konjac Root)
How it works: A soluble fiber that expands in your stomach, promoting a sense of fullness and reducing calorie intake.
- Dose: 1g 30 minutes before meals, 2–3 times daily
- Effectiveness: Reduces appetite, supports digestion
- Safety: Safe when taken with water (never dry swallow due to choking risk)
✅ Best for: People who overeat or struggle with portion control
2. Green Tea Extract (EGCG)
How it works: Rich in antioxidants and caffeine, it boosts metabolism and increases fat oxidation—especially during workouts.
- Dose: 250–500 mg daily

- Safety: Avoid taking too close to bedtime or if you’re caffeine-sensitive
✅ Best for: Active people wanting more energy and faster fat burn
3. Garcinia Cambogia
How it works: Contains HCA (hydroxycitric acid), which may block fat production and suppress appetite by increasing serotonin.

- Effectiveness: Supports mild fat loss over time
- Safety: Mostly safe, but may cause bloating or digestive discomfort in some users
✅ Best for: Beginners looking for gentle appetite control
4. L-Carnitine
How it works: Transports fatty acids into your cells’ mitochondria, where they’re burned for energy.

- Safety: Safe in normal doses; may cause slight nausea in sensitive users
✅ Best for: Gym-goers or athletes seeking performance + fat loss
5. Apple Cider Vinegar (ACV) Gummies
How it works: May help lower blood sugar, curb appetite, and support digestion.
- Dose: 1–2 gummies per day
