Ken - A consideration may be the brand of the probiotic you experimented with and the extra (unnecessary) ingredients included in the formulation. See below two typical high-quality probiotics compared to Align.
Ive used both with no gastric distress. In fact, in all my many years of using probiotics, Ive never experienced a gastric problem. As we say, we are all different but often fillers and other extraneous chemicals add to stomach distress. The most important issue would be the quality of the probiotic or viability... if most are inactive even before consumption, then there will be no benefit and a total waste of money. There are a lot of brands out there that fall short of being effective.
Probiotics are an important part of intestinal health and overall health since over 70% of the immune system lies in the GI tissue.
