Our verdict
ColonBroom is the fiber route: 3.6 g of psyllium per scoop in a sugar-free strawberry drink. At the brand's two scoops a day, a 60-scoop bottle lasts 30 days, and prices start at $27.99 a bottle, or $0.93 a day, on the six-bottle subscription. Psyllium is one of the best-studied fibers for regularity.
Bioma is the probiotic route: two capsules a day with a Bifidobacterium blend, XOS and tributyrin, and no drink to mix. A bottle lasts 30 days, and prices start at $26.41 a bottle, or $0.88 a day, on the six-bottle plan.
Both of those prices are subscriptions, because both stores open on their plans. Each lets you switch to a one-time purchase at a higher price per bottle, and both say cancelling a plan before the second charge means paying back the discount. Returns cover unopened bottles: ColonBroom, 14-day returns (unopened); Bioma, 14-day returns (unopened).
Both have solid buyer ratings on Trustpilot, around 4 out of 5 from thousands of reviews. Pick the one that fits the habit you'll keep: a glass of fiber before meals, or two capsules with no taste at all.
Pick ColonBroom if…
- You want a fiber drink aimed at regularity
- You like a flavored drink as part of your routine
- You want one well-studied ingredient with the dose on the label
Pick Bioma if…
- You'd rather swallow two capsules than mix a drink
- You want probiotics plus prebiotic fiber
