See our full sample process →Concentrated at 4:1 from the bark of white willow, Salix alba, a large tree native to Europe, western and central Asia, and North Africa, this powdered extract is carried on maltodextrin, a mild plant-derived carbohydrate carrier. Bio-Botanica supplies it full-spectrum and non-standardized for supplement and food-and-beverage developers, and the maltodextrin carrier dissolves readily, supporting both dry and reconstituted applications.
White willow bark is a long-trusted name in botanical comfort and joint formulas, and it holds steady demand as brands assemble plant-based blends for active and aging consumers. Active-lifestyle and mobility-focused product lines lean on recognizable heritage botanicals, and a 4:1 concentrate on a soluble carrier lets formulators deliver a meaningful willow bark level in the compact fills that capsule and tablet lines require.
The dry powder suits capsules, tablets, gummies, stick-packs, and dry drink blends, dispersing readily into powder bases. White willow is traditionally associated with bone and joint and nervous-system support, which brands may reference for structure/function positioning only, not as a consumer health claim.
Bio-Botanica has been family-owned since 1972 and extracts at an FDA-inspected cGMP facility in Hauppauge, New York, where this bark is processed with the proprietary Bio-Chelated low-heat method to retain a Holistically Balanced profile of naturally occurring constituents. Each lot passes onsite HPLC, ICP/MS, microbial, USP, and heavy-metal testing, and Kosher, Halal, and Organic certification is available on request.
