R&D Insights: Solving Bioavailability & Formulating High-Stability Flavonoids

Technical guidance from our phytochemistry and application engineers.

Formulating with natural Flavonoids like Kaempferol presents specific physical challenges: as a hydrophobic polyphenol, raw Kaempferol exhibits low water solubility and poor oral bioavailability, which often restricts its performance in liquid dietary supplements and functional beverages.

Our extraction R&D team solves this by utilizing advanced crystallisation and precision micronization technologies. By controlling crystal polymorphs and particle size distribution, we optimize powder flowability for direct compression capsules and tablets. For liquid applications, our tech support team provides customized lipid-carrier/liposomal integration strategies, ensuring your finished product delivers high bioavailability without color degradation or precipitation.
