Great for exactly what it claims!

Posted   by Kristen from CEDAR RAPIDS, Iowa
After a long struggle with bowel irregularity and bloating, this is one of MANY things I tried and have kept in my daily routine. I notice when I don't take it and am diligent to get back on track. I have recommended it to a few people with similar digestive issues. A great product for exactly what it claims - thanks, ReNew Life!

Best for daily fiber & intestinal health

Posted   by Jon from SAN FRANCISCO, California
Tried everything on the market. Literally. This is gentle on your tummy and keeps this running regularly. Works well if things are plugged or running too faster either way. Give it a try - thank me later : )

Fiber smart is really good for my digestion. It took around 3 days to produce any effect, but now I take it daily and have no digestion problems.
