Our formula includes organic whole turmeric root so that you get all of the compounds of the complete herb, in its pure form. We have also included a very potent extract with 95% standardized Curcuminoids. Curcumin is poorly absorbed into the bloodstream. It helps to consume black pepper with it, which contains piperine, a natural substance that enhances the absorption of curcumin by 2000%. We have included not only organic black pepper but organic ginger to ensure maximum absorption. Why Choose Herbal Roots? Unlike other brands, you will NOT find binders, fillers, preservatives or additives in any Herbal Roots supplements. This product is USDA Certified organic, manufactured by a cGMP facility, and 3rd party tested. Herbal Roots is a small family, women owned, and operated business.
