Product is a high purity flavonol from Japanese Pagoda Tree buds. Unlike synthetic alternatives or fruit-derived versions, our extract is more consistent and scalable.
You struggle with seasonal supply instability and uneven potency of raw botanical powders. Our standardised extract resolves these problems and is guaranteed to contain 98% quercetin dihydrate (CAS 117-39-5) as proven by HPLC testing.
We overcome the frequent bioavailability bottleneck of generic flavonoids. We use ultra-fine particle technology to improve the rate of dissolution and the efficiency of absorption. This increases the effectiveness of your capsules, pills and water soluble formulations.
The stable dihydrate form resists oxidation and moisture uptake. Your products are fully potent throughout their whole shelf life, reducing complaints and returns due to quality.
