Ox bile, providing bile salts, in a vegetarian capsule.

A simple material with a long history in practitioner use, and one where the strength you choose matters. This is the lower of the two strengths Allergy Research Group offers, which gives a practitioner somewhere sensible to start.

One ingredient, hypoallergenic, nothing else in the capsule. That has been the brand's approach for more than 45 years.
