Buying Guide
What to look for when choosing a green tea extract:
- Potency and standardization: Look for EGCG percentage (commonly 50%), catechins, and polyphenol levels to gauge strength and consistency.
- Form and dosage: Capsules are convenient; liquids and drops may offer faster absorption but require more frequent dosing. Choose based on preferred intake.
- Source and quality: Organic certifications and GMP-compliant manufacturing offer additional quality assurance. Non-GMO and vegan options suit certain diets.
- Caffeine content: Some extracts include caffeine; consider your sensitivity and daily caffeine budget when comparing products.
- Supply and value: Larger bottles with long-term supply can reduce cost per serving. Check capsule count and serving size to assess value.
- Allergen and ingredient notes: Check for fillers or binders if you have sensitivities or dietary restrictions.
