Can I Take fiber supplement with probiotics?

SUMMARY:

Fiber supplements and probiotics are generally safe to use together; some fibers (prebiotics) can support probiotic growth, though starting both may increase gas or bloating in some people.

ADDITIONAL NOTES:

Many fermentable fibers (eg, inulin, FOS) act as prebiotics and can promote probiotic growth. Bulk-forming fibers (eg, psyllium) are not known to cause harmful interactions with probiotics but can change intestinal transit. Common, mild side effects when starting either or both include gas, bloating, and abdominal discomfort. Also note that fiber supplements can reduce absorption of some oral medications, so keep that in mind if you take other drugs and discuss dosing timing with a clinician or pharmacist.
