Hi Vere,Yes I have tried Zylax. I am a New Zealander and the product is also made here - but I discovered it on the web about 4 months ago.I notice that the manufacturers have got a post in the product and website section of this siteI have recently been diagnosed as suffering from IBS C - but have had problems for the last couple of years.I have tried a great cocktail of prescription and dietary supplements, and have found that for me anyway Zylax works the best.It is as I have been told a natural digestive enhancer, based on a digestive enzyme complex that has been extracted from kiwifruit.The theory being that a digestion system that is working as it should, will help to relieve symptoms such as Constipation, Indigestion, Gastric Reflux and even symptoms of IBS.I have to admit that I was sceptical to begin with, however I started off as recommended by taking a couple of capsules before each meal, and began to notice an effect of taking the product after 3 weeks.Again as recommended I then reduced the dosage to 1 - 2 capsules per day.As a result of taking Zylax, I am less bloated, have less pain from BM's and have pretty much regular bm's, I feel that I am evacuating my bowels completely for the first time in a long time.I am keeping on with other medications as well - and that is the beauty of Zylax. It is completely natural, and doesnt interfere with other meds.Being a natural product results do vary from person to person. You have to remember too that it is a product that is designed to enhance your digestion, so as the manufactuer puts it - it treats the cause rather than the symptoms.However by treating the cause - it at the same time provides relief from the symptoms such as Constipation, Indigestion, Gastric Reflux etc.This may not be for everyone - but it certainly works for meCheersMax
