Overview
Slow-fermenting soluble fiber is the working part here: Sunfiber breaks down gradually in the gut, so it feeds good bacteria without the sudden gas some fibers cause. One scoop dissolves clear in water or another still drink.
Its low FODMAP certification makes it a reasonable fit for sensitive digestion, and it is meant to help with both occasional constipation and diarrhea. The container is large, which suits daily users but takes up shelf space.
Who it's for
Suited to people following a low FODMAP plan or prone to bloating with other fibers. Those who want fiber in a flavored drink mix will find this plain powder less appealing.
Pros and cons
- Low FODMAP certified for sensitive guts

Performance notes
Fiber that ferments slowly releases gas gradually, which is why this powder causes less bloating for many sensitive stomachs. It also slows how fast food leaves the stomach, helping you feel full and supporting regular bowel movements.
