Bu araştırma, laktoz intoleransı (lactose intolerance) olan kişilerde probiyotik takviyesinin laktoz sindirim güçlüğü üzerindeki etkisini incelemektedir; çalışmada probiyotik, laktaz enzimi (Lactase) ve plasebo karşılaştırılmıştır. Çalışmaya, laktoz intoleransı olduğu bilinen ya da şüphelenilen, 25-60 yaş arası sağlıklı yetişkinler katılabilmiştir. Çalışma faz uygulanmayan bir çalışma olarak yürütülmüş ve tamamlanmıştır.
