I find heartburn relief with apple cider vinegar gummies after years of struggling. my doctor mentioned that it could cause silent gerd and stomach inflammation. are you likely to have silent gerd if you used to suffer from full-blown gerd?

Silent GERD is a thing, but I wouldn't worry about it much. I suspect their comment was wondering why adding an ingested acid product (vinegar) to a reflux problem would help. I suspect it has less to do with the apple cider vinegar than the gummies. It has been known for decades that simple carbohydrate sugars will settle the stomach. I suspect a little honey or karo would help you as well.
