Functional Herbals, LLC, the makers of DrH ReJoint, is committed to offering products with unparalleled efficacy. We believe that like all living things, herbs reflect, and absorb the environment in which they grow. Thus, the therapeutic effect of the same herb, grown in two different environments will be remarkably different. Our herbs are specifically chosen based on the conditions within which they grow. Our herbs are grown in soil which is of volcanic origin and hence very rich. With sun, humidity and rain in the ideal balance, and an extraction process which preserves the medicinal value of the herbs, our Dr H ReJoint formula is literally unparalleled. We could purchase the same ingredients at 1/5th the cost, but we refuse to cut corners, because that would mean sacrificing the quality of your health, and thus your happiness. Every batch of our herbs are 3rd party-tested for heavy metals, total Aerobic count, Staphylococcus Aureus, E. Coli, Salmonella spp., total Fungi and Enterobacteria counts. Our herbs are stored and processed in facilities which are gluten, soy, peanut, corn, and dairy free, however this should not be used as a guarantee for those with serious sensitivities to these foods. Our herbs are manufactured in a certified, GMP facility, which is also licensed by the FDA to manufacture pharmaceuticals.
