I bought this product based upon all the glowing reviews. I'd hoped that it would help with my GERD condition which, after many years, barely responds to prescription medication (I've tried them all). After a month's use the condition is unchanged, the Jarrow has had no affect on my lower GI, as my bowel movements are the same, and I certainly do not feel any more energy. I will continue to finish off the box and, if my conditions change, I will revise my rating.I do not doubt the favorable reviews but, based upon my experience, this product is not a cure-all(or a cure-everyone).
