Lactose Intolerance Clinical Trial

Official title:
Incidence of Lactose Intolerance Among Self-reported Lactose Intolerant People

Clinical Trial Summary

This is a 3-sites, double-blinded, randomized, 2X2 cross-over study aiming to compare effects of milk containing only A2 type beta casein versus milk containing both A1 and A2 beta casein proteins on the gastrointestinal symptoms for the health people who self-reported to be lactose intolerant.

Clinical Trial Description

Study sites: Shanghai, Guangzhou, Beijing

Eligible subjects were enrolled in the study and randomized into one of the 2 study arms:

Sequence A1-A2: Oral consumption of milk containing both A1 and A2 type beta casein at Visit 1 and milk containing only A2 type beta casein at Visit 2; Sequence A2-A1: Oral consumption of milk containing only A2 type beta casein at Visit 1 and milk containing both A1 and A2 type beta casein at Visit 2.

Washout period: 2 weeks between Visit 1 and Visit 2 ;
