My brother in America has been taking these capsules for several years and I started taking them on his recommendation. He is a research scientist so knows what he is talking about! However, until recently I have been having to rely on him to keep me supplied as apparently they were on the list of things prohibited by the US to be exported. So I was very pleased to find that I can now buy them myself direct BUT I consider the postage price to be extortionate.
The parent company is Mars candy. This is one of the very few dark chocolate products that passed lead and cadmium testing. Also it has only 1 carb per 3 capsule serving. Recommended.
