The scientists who discovered and developed Amarasate®, the active ingredient in Calocurb, found canola oil to be the best solution to for the release and spread of Amarasate® extract in the upper intestine. Canola oil is a highly stable mono-unsaturated oil, with a high vitamin E and one of the best omega 3 to 6 ratios of all vegetable oils. Our oil is certified Non-GMO expeller pressed, glycophosphate free canola oil. Dr Edward Walker (one of the scientists who discovered and developed Amarasate®), has recorded a few videos explaining why canola oil is used in Calocurb.
