I take a probiotic also and find it helped me a little.
The best way I can control my acid refuux and heartburn is by losing weight. It happened 10 years ago when after a strict diet, 20 pounRAB thinner, I suddenly realised I hadn't had any heartburn for a while. Recently I (having regained about all of it back) began exercising regularly and am now down around 13 to 15 pounRAB --- and lo and behold, my acid reflux is entirely missing on some days, and only slight on others. I still take the probiotic anyhow. Hoping it stays gone.
I think taking them is helpful and not harmful as are many other acid reduceing types of pills.
