Tea polyphenols are naturally occurring bioactive compounds found in tea leaves, possessing significant antioxidant properties—100 times stronger than vitamin C or vitamin E. We offer tea polyphenols with a purity of 50%-98%, extracted using a patented low-temperature supercritical extraction technology. This not only preserves the highly active catechins but also eliminates the excessive bitterness and clumping issues common in traditional processing methods, making it a truly "formulation-friendly" and clean raw material.Sources:https://www.hongdanaturals.com/natural-herb-extract/green-tea-extract-polyphenols You can trust our standardized extracts to deliver sustained and stable health benefits to your customers.
