Dietary fiber intake / regularity

Limited Evidence

Contributes to overall fiber intake; like other fibers, can improve stool form and modestly affect glucose and cholesterol. Specific RCTs on pea fiber are modest in size.

How it works

Pea fiber contains a mix of insoluble fiber (cellulose, hemicellulose), pectin, and small amounts of resistant starch. Insoluble fiber adds stool bulk, while soluble portions are fermented by gut bacteria into short-chain fatty acids that support colon health. Pea fiber is also used as a binder and texturizer in plant-based meats and protein products.

Dosage

There is no specific RDA for pea fiber. General dietary fiber recommendations are 25 g/day for women and 38 g/day for men. As a supplement, pea fiber is typically used at 2-10 g per serving.

When and how to take it

Can be taken with meals to support satiety and glucose response. Drink plenty of water alongside fiber supplements.
