One report found bromelain improved the action of antibiotic drugs, including penicillin and erythromycin, in treating a variety of infections. In that trial, 22 out of 23 people who had previously not responded to the antibiotics did so after adding bromelain four times per day. Doctors will sometimes prescribe enough bromelain to equal 2,400 gelatin dissolving units (listed as GDU on labels) per day. This amount would equal approximately 3,600 MCU (milk clotting units), another common measure of bromelain activity.
