2017 Study: a2 Milk® is Easier on Digestion†

Posted on February 21, 2018

First, let me start with a disclosure: I am a science nerd. I love hypotheses, methods, and results. I read health and science journals for fun. So, when a new study on the effects of a2 Milk® was published, I spent hours digesting it (pun intended). If you’re a science nerd too, you can read the full-text study. Or read on for a summary.

The Study

The objective of this study was to support the notion that for some people A1-protein free milk may be easier on digestion† than ordinary A1 and A2-protein milks. Currently, there are a handful of studies that suggest A1 protein free milk does not cause the stomach discomfort that some people experience when drinking ordinary milk. However, most of these studies involve a small number of test subjects. In this 2017 study, there were 600 participants.

Published research suggests that drinking a2 Milk® may help avoid tummy discomfort in some people.

If drinking ordinary milk causes you tummy discomfort, try replacing it with a2 Milk®.
