Why Choose Our Luteolin?
Precision Purity for Professional Formulations
High-Purity, Consistent Quality
Built on our 98% crystalline monomer purification process, both our 95% and 90% grades deliver reliable purity with a well-characterized impurity profile verified by HPLC. Each batch is tested to confirm high flavonoid bioactivity and batch-to-batch consistency.
Food-Grade Ethanol Extraction
Safety is our priority. We use food-grade ethanol as our primary extraction solvent. Residual solvent levels are routinely tested and controlled in accordance with ICH Q3C / USP <467> requirements, ensuring freedom from harmful solvent residues such as methanol or chloroform.
Stability & Reliable Shelf Life
Our advanced recrystallization process delivers superior thermal stability and a consistent bright yellow appearance. When stored in sealed, dry, and light-protected conditions, our luteolin maintains quality for up to 24 months, as supported by accelerated stability data.
How to Choose Your Grade?
Premium Grade (95%)
Recommended for high-end dietary supplements and functional formulations. Well-suited for products targeting cognitive health support or healthy aging, where purity and consistency are critical.

Functions
Evidence-Based Biological Mechanisms
Antioxidant Support
Luteolin is a naturally occurring flavonoid with recognized free radical scavenging properties. It may help protect cells from oxidative stress and support the body’s natural antioxidant defense system.*
Anti-Inflammatory Support
By modulating key inflammatory signaling pathways, luteolin may help maintain a healthy inflammatory response. It has been studied for its role in supporting joint comfort and overall inflammatory balance.*
Cognitive Function Support
Preclinical research suggests that luteolin’s antioxidant and anti-inflammatory actions may help support neuronal health and cognitive performance, particularly in areas of memory and mental clarity.*
Skin Health Support
Emerging research indicates that luteolin may help protect skin cells from environmental stress and support skin elasticity and appearance by inhibiting matrix metalloproteinases (MMPs) associated with premature aging.*
Metabolic Health Support
Studies suggest that luteolin may help support healthy glucose metabolism and lipid profiles, positioning it as a complementary ingredient in metabolic wellness formulations.*
