This is a tough question and most likely your Dr. should advise you on the use of HCl. there seems to be lots of thoughts from people that have both GERD and gastritis.
One person posted, "If you take HCl, how can that ever have any effect on the stomach? Doesn't the stomach produce far, far more HCl by itself than you could ever take orally? After all, HCl production is the stomach's main task..."
Food for thought.
Have a great Thursday,
