I came across your web page a couple of weeks ago. I have been on acid reflux medication for 10+ years (nexium, omeprazol, etc.). I decided to give ACV a try - I bought organic with "mother". At first I used 2 teaspoons of ACV in a glass of water (I was surpriesd the taste is OK) twice a day but I still had heart burn during the day. I increased to 2 TABLEspoons of ACV in a glass of water twice a day and it seem to be the right amount. I still experienced some minor heartburn in the late afternoon but I treated this eating an apple. Since I intruduced the apple for minor heartburn I have been free of acid reflux symptoms. From my experience, the amount and frequency of ACV needed is determined by trial and error. I feel very confident on the effectivness of ACV and I am gladd to be of the acid suppression medications.
