The science of Optizorb technology

Optizorb technology contains three main ingredients which are: alginic acid that draws fluid from the stomach into the tablet causing it to swell and break apart; calcium carbonate that works together with alginic acid to boost the disintegration of the tablet and, crospovidone which acts as a superdisintegrant due to its ability to dissolve well in water.1,2
