Always consult your health practitioner if in doubt.
RiskLow Risk
Overview
•The 450 mg EGCG dosage is below the 800 mg/day threshold associated with liver toxicity risks, with safe upper limits around 338-800 mg/day from regulatory assessments.
•Potential mild side effects include nausea, headache, or nervousness due to low caffeine content (~30 mg/serving); discontinue if these occur.
•Not recommended for pregnant, nursing women, children under 18, or those with liver conditions, high blood pressure, or diabetes without medical advice.
•Possible interactions with nadolol and other beta-blockers via OATP transporters; limited evidence for major CYP450 or P-gp interactions.
•Bovine gelatin poses low risk but may concern vegetarians or those with bovine allergies; facility processes common allergens like milk, soy, and nuts.
•Long-term use appears safe at this dose based on clinical trials, but monitor liver enzymes with prolonged high-dose supplementation.
