Excellent relief for heartburn

This is excellent if you have heartburn. It is my go to and it works every time. I use the one that you drop in the water. I know there are chewables, but this is something that I know that works so I will continue and I would highly recommend anyone who suffers from heartburn to try this.

The Un-Burn

I absolutely love this product. It works right away on my acid reflux %26 heartburn. It's so easy to make %26 doesn't take much. It doesn't taste great, but if I can handle it, then anyone can handle it. If it's that terrible, just breathe through your mouth after. Try it. Feel the UN-BURN. You'll feel so much better. 😉

I have very serious digestive issues. This product is simple. It doesn't have a negative interaction with my seven prescription medications. I feel the relief immediately! It's wonderful. I couldn't give all five stars across the board because the after taste isn't good. Still it does the job bar none!
