Usage & Dosage
How to Use

Suggested Dosage
Dried powder: 500-2000mg daily. Standardized extract (95% curcuminoids): 500-1000mg with BioPerine. For inflammation/pain: 1000-2000mg of curcuminoids daily. Best taken with food containing fat.
Quality & Storage
Harvest Season
Year-round in tropical climates; usually harvested at 8-10 months of growth when leaves yellow. Rhizomes are boiled, cleaned, and dried.
Quality Indicators
Vivid deep orange-yellow color, strong earthy aroma, bitter spicy taste. Standardized extracts should be 95% curcuminoids. Look for C3 Complex (three curcuminoids). Curcumin with BioPerine (black pepper extract) for better absorption. Alleppey turmeric from India is considered premium.
