The physicians of Cardiovascular Consultants insist upon the highest standards for quality in the supplements offered by CardioTabs. This means manufacturers are carefully selected for their compliance with current good manufacturing practice (cGMP) and their vendor certification programs. We rely upon third party certifications where available or perform routine site visits to assure that our standards are maintained. We follow our own standard operating procedures (SOP's) for quality assurance that cover all aspects of manufacturer qualification, product retention, and product testing. In accordance with those standards, our products are routinely tested for label claim compliance and for contaminants by a major, independent testing laboratory.
