My best ally for the stomach

This product is really good, every time I feel sick to my stomach I use it and it is very effective. There are 2 round tablets the size of a 25 cent coin in each envelope. It is very easy to use, in a water rate I put the two tablets and wait for them to start to effervesce and then I take it and in about 10 minutes I begin to feel relief. Each box has 72 tablets. I always have these tablets at home. I can’t miss them. I’m really good. I highly recommend them

Excelente product

It is an antacid designed for the rapid relief of heartburn, acid indigestion, and stomach upset. It is ideal to have on hand after heavy or spicy meals to prevent that burning sensation that often occurs shortly after eating.

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.
