RiskLow Risk
Overview
•Reishi extract at 500 mg (20:1) is generally safe for adults, with low risk of side effects like mild digestive upset; dosages align with studied ranges up to 9g equivalent daily.
•Terminalia chebula 50 mg extract poses minimal risk but may cause mild GI irritation in sensitive individuals; safe within limits for short-term use.
•Vitamins C (15 mg) and B1 (1.1 mg) are well below UL (2000 mg and 100 mg respectively), posing no overdose risk and supporting immune/heart functions without interactions.
•Vegan HPMC capsules reduce allergen risks compared to gelatin; no major contaminants reported in Holland & Barrett products.
•Suitable for healthy adults, but consult doctor if pregnant, breastfeeding, or on blood thinners due to Reishi's mild anticoagulant potential.
•Long-term use appears safe based on traditional evidence, though monitor for rare liver effects with high Reishi doses over months.
