Check-In Health:
Acid reflux is caused by calcium, salt, enzymes, pepsin, HCl, bile etc deficiencies.
Apple Cider Vinegar, known as ACV also helps if you have before each meal.
3 enzymes at least 15 minutes before each meal is recommended. 1 tablespoon of ACV in 1 cup of water also taken with the enzymes will be good before meals.
Strong stomach acid needs calcium and salt as well as the others mentioned above, so a complete supplement protocol is needed.
Another thing that works is 200c potency chamomile.
Acupuncture works too, reversing the polarity of the muscle. Often there is a hiatal hernia pushing up the stomach.
There is also a simple surgery that can correct the problem. I know of two people who got it done and are happy with the results.
