Product Introduction of Black Walnut Extract

Black Walnut Extract (10:1) is a concentrated botanical powder derived from the hulls of Juglans nigra, a tree native to North America. The 10:1 ratio means 10 kg of raw hulls are used to produce 1 kg of extract, maximizing the concentration of active compounds like juglone, tannins, and polyphenols. It appears as a fine dark brown powder with good solubility and stability. Produced under strict quality control, it is free from heavy metals, pesticides, and microbial contaminants, meeting international food and supplement standards. This high-potency extract preserves the natural benefits of black walnut hulls in a convenient, easy-to-formulate format.
