Crossroads Apothecary and our affiliated doctors are interested in using the highest quality supplements for our patients in order to maximize results. A majority of the product brands we carry are available only through qualified Health Professionals due to their quality and potency. Many of our products are also free of allergens and fillers while providing the highest quality ingredients. These companies do extensive testing through independent labs who verify these requirements. The end result is products that have the greatest chance of providing the desired results for both doctor and patient.
