it's actually a soluble fiber, and it has a prebiotic effect so it will help the probiotics grow in your gut. Sounds great, right? But, when I was researching Acacia I saw some studies on FOS and inulin (they're very similar) that show these are soluble fibers that when extracted from foods in a pure form are really likely to cause a lot of bloating and gas (and in higher doses, even diarrhea) in people.
If you've ever take Fiber Choice chewable tablets, that's inulin, so if you've had trouble with bloating and gas from that be really careful with the FOS. There might not be very much of it in the probiotics you bought, in which case there's likely no worries. And you might tolerate FOS just fine. But be aware just in case.
