Our verdict

A multi-fiber capsule for people who want regularity support without mixing a gritty powder. The capsules are gelatin, so the vegan label in the specs does not hold, and fiber grams per serving are not given.

Overview

Not a psyllium-only supplement, Yerba Prima's Daily Fiber Caps blend psyllium husk, acacia gum, soy fiber, oat bran and apple fiber in one capsule. The mix supplies both soluble fiber, which softens stools, and insoluble fiber, which adds bulk.

Variety of fiber sources is the reason to choose it, plus the convenience of swallowing capsules instead of drinking a thick shake. Capsules carry far less fiber than a scoop of powder, so reaching a meaningful dose takes several. Soy fiber and a gelatin shell rule it out for some diets.

Who it's for

Adults topping up a low-fiber diet who dislike powders get a simple capsule routine. Vegans, people with soy allergies and anyone needing a large fiber dose quickly should look at a powder instead.

Pros and cons

Pros
  • Five fiber sources in one capsule
  • Both soluble and insoluble fiber
  • No mixing or drinking a thick shake
  • Non-GMO and gluten-free
Cons
  • Gelatin capsule despite vegan label
  • Fiber grams per serving not listed
  • Contains soy fiber
  • Several capsules needed per dose

Performance notes

Soluble fibers like psyllium and acacia absorb water and soften stools, while insoluble fibers add bulk that moves waste along. Results depend on daily fiber intake from food plus the capsules, and on drinking enough water. Capsules release the fiber in the gut instead of thickening in a glass.
