Overview
•At 400 mg green tea extract (200 mg EGCg), dosages align with safe limits from NIH and Mayo Clinic, with low risk of liver toxicity for healthy adults under 800 mg EGCg daily.
•Potential mild side effects like stomach upset or caffeine-related jitteriness from trace amounts; no high caffeine content in decaffeinated-like formulation.
•Interactions possible with blood thinners (e.g., warfarin) or stimulants due to catechins; consult physician if on medications per WebMD.
•Generally safe for adults, but avoid in pregnancy/breastfeeding due to limited data and potential fetal effects (EFSA guidelines).
•No major allergens; suitable for most, but sensitive individuals may react to catechins. Quality assured by NOW Foods GMP standards.
•Long-term use safe at recommended doses, but monitor liver enzymes if history of issues, as high catechins may pose rare risks (PubMed reviews).
