I have alot of this condition over the years . Someone mentioned to use Apple cider vinegar , with mother in the solution . Organic , unfiltered and unpasteurized . In non-reactive bottles , to protect nutrients breakdown from light , through photo- oxidation . The ACV that I use has ; :No chemicals additives or preservatives :Unpasteurized , which preserve nutritional value :contains pectins , benefical bacteria and enzymes : contains " mother " formed naturally by unpasteurized vinegar ( is not harmful or spoiled , which is the strands of proteins , enzymes and friendly bacteria which gives the product a murky , cobweb appearance ). : packed in opaque , non-reactive bottles , plastic in my case . Which is BPA FREE . Further , heartburn is not due too much acid in the stomach , but the LACK of STOMACH ACID . The older you get the less stomach acid you produce . And stomach acid is critical to getting the nutrients from your foods . So I took 2tbsps ( table spoons ) in 8oz of water . ( try 4oz ) if you can . The less diluted the better . But ACV , is an acid , after all , 5% acetic acid . Hard on the teeth enmmal . So I would recommend brushing your teeth right after drinking , or consume through a straw . It worked great . No more problems with acid reflux . It may not work for you , but it sure did me. Warning : I have tried two table spoons straight , the first table spoon was fine , the second , it burned big time , luckly I had chaser of water just in case . ALSO do not take if you have stomach ulcers , it will aggravate the ulcer .
