Only Bioperine® used in Bosmeric-SR® is guaranteed to be standardized to 95% piperine. All other generic black pepper extracts are not. Also, the amount of BioPerine® used in each caplet of Bosmeric-SR is at the optimum clinical dose for enhancing absorption at 5 mg, unlike other products that use between 1-2 mg.
