Bowel regularity/fiber intake

Limited Evidence

Insoluble fiber generally improves stool bulk and frequency. Specific bamboo fiber trials are limited.

How it works

As an insoluble fiber, bamboo fiber adds bulk to stool, accelerates intestinal transit, and contributes minimal calories. It is non-fermentable to a large extent, so it generally does not cause significant gas. It is used as a fat replacer in baked goods, a flow agent in supplement tablets, and a fiber additive.

Dosage

No RDA. Dietary fiber recommendation is 25-38 g/day total fiber. Bamboo fiber is used at varying levels in formulated foods.

Safety

GRAS for food use. Insoluble fibers should be taken with adequate water. Generally well tolerated, with low gas-forming potential.

Who should be cautious

People with intestinal narrowing or obstruction should avoid bulk fibers. Most others can use freely with adequate water.

Interactions

Like other fibers, may modestly slow absorption of co-administered medications; separate by 2 hours if relevant.
