We take quality and safety extremely seriously and BerbaPrime is produced and controlled to international quality standards throughout every step of the manufacturing process. BerbaPrime is manufactured in the USA in an ISO9001 and Good Manufacturing Process (GMP) certified facility using authentic, reputably sourced Chinese berberine. Our berberine is thoroughly tested and verified as authentic and of the highest quality, and it undergoes strict quality control processes to ensure it is pure, safe and effective to use in BerbaPrime. Throughout the entire manufacturing process we follow HACCP guidelines along with rigid internal safety and cGMP protocols to protect the integrity of the product from start to finish. We also use transparent capsules, enabling you to see and verify the color of the berberine inside. BerbaPrime is yellow in color, although the berberine plant can vary on the color spectrum from orange to yellow hues. All this means you can be sure that when you purchase BerbaPrime, you are getting a safe, genuine, effective supplement of the highest quality.
