I have used Deva products before and have always loved them. I do like this product... it works well, but it gives me heartburn.I tried switching to take in the morning, with a meal, without a meal... no matter how I switched it up, I still had heartburn. Nothing else about my diet or routine changed.I would buy this product again and other Deva products, but I'm also considering other brands for probiotics.UPDATE: The indigestion subsided after a few weeks and I no longer experienced it. Because of this, I would definitely buy again and I updated from 4 stars to 5 stars.
