As a physician i am never against natural remedies. But the same people that write all the natural crap remedies and talk shit about modern medicine all the time are the quickest patients to run to the hospital when they have a stroke, cancer, or heart attack requesting the latest medication and treatment to save their lives. The cider works for some, and not mostly for others. Baking soda gives instant relief but you are back to doing it every day as the acid production is neutralized for that instant moment. Rolaid and tums fall in same category. Your only two other options are H2 blockers such as Rantidine, famotidine etc and they work better but is chasing the horse after it has already left the barn. It is like comparing tamoxifen and letrozole. H2 blockers are trying to fight at the receptor site. Your best option is a PPI (proton pump inhibitors). They nip things at the bud. They reduce actual acid production.
If it wasnt because of increased acid production then why millions of people are getting relief within 2-3 days of taking a PPI. If the theory of not enough acid in the stomach was true then these millions of people should be getting worse heart burn and these drugs would be utter failures within months of hitting the markets. The first of its kind was Prilosec which was prescription and it changed the face of heart burn in medicine. After its patent ran out it is available over the counter as omerprazole or Prilosec OTC. I recommend starting at 20mg daily and if you have seen a complete stoppage at end of the week the continue at 20mg daily, if not then increase to 40mg daily taken all at once. I promise your heartburn will go away.
