From start to finish, Mason Natural supplements are passed through our robust quality process. All products are manufactured in the United States, adhering to the US Food and Drug Administration’s guidelines. With over 44 years of experience and a skilled professional team, we continue to work closely with our suppliers to select and test ingredients prior to manufacturing. We are dedicated to maintaining the highest standards of quality. Our manufacturing processes follow the dietary supplement cGMPs.
Our Quality Assurance technicians work independently from our manufacturing personnel, so as to eliminate any conflict of interest. This allows our QA team to accept or reject raw materials based on test results. Finished goods are subjected to rigorous analytical testing including organoleptic, microbiological, disintegration and/or dissolution. All active ingredients are assayed or identified properly. Tests on finished goods are also performed at independent FDA approved facilities that are not affiliated with Mason Vitamins.
Mason Vitamins undergoes regular inspections by federal, state and county agencies to ensure regulatory compliance at every level. Our facility is consistently audited and certified by a leading independent company.
