Really Helps

Posted by 5302833699472003141 on May 02, 2016

This product really helps me with my stomachaches. I started using it since last year and I would recommend it to anyone. It really took the pain away.

Good product, but not as effective as some

Posted by 5360918278168326329 on Apr 08, 2016

I have used a similar product before with great results, but wanted to try out other products in comparison. I take it that it might come down to individuals so that what works for one doesn't work for another. I use this to relieve and control my acid reflux, which can get bad especially during the night. This one doesn't remove all the symptoms, but I can notice it helps a bit and reduces the symptoms. However, for me CarnoSoothe by Life Extension has been better and even life-changing, with a stronger effect and it almost completely removing my acid reflux problems. As I said, I do believe that perhaps for someone else this product is better, but I'll switch back to CarnoSoothe since the difference is huge.

Calcium carbonate?

Posted by emanuela on Jun 20, 2015

Not used regularly for long-term digestive issues (previous H. Pylori infection, GERD etc), because it does not help at all in the short term (made things worse). It seems that it is weaker than Source Naturals' which could be because they recommend taking two capsules twice a day (while Doctor's Best recommend just one capsule twice a day), the PepZin content in one capsule is the same. Other concern: The Doctor's Best PepZin GI bottle I purchased a year ago lists "calcium carbonate" as the first ingredient in the "other ingredients" list. Now, that is an unwelcome discovery, as this ingredient is used as an antacid and so could well impair digestion. Iherb does not list calcium carbonate, so you may want to double-check before you purchase. Hope this is useful.
