Acid reflux is often caused by a Vitamin B12 deficiency. Since you need B12 to make enough intrisic factor and enzymes to absorb it, perhaps just taking ACV will help you absorb Vitamin B12 better.
Nevertheless, I have found that as long as I take 4 B12 dots (500 mcg) under the tongue once a day, I am fine. When I don't, the reflux comes right back.
