Research-backed fiber, with flavors that are delicious by design.
Two formulas, engineered differently on purpose. Every ingredient is research-backed and plant-based.
Your daily scoop.
The gold standard of soluble fiber. Gels up, gets things moving.
Prebiotic fiber. Feeds your good gut bacteria.
Apples, berries, cacao. That's the whole flavor list.
Regularity, to go.
Nature's original fiber delivery system.
Fiber plus omega-3s. Heavily studied, tiny package.
A traditional digestive ally, wrapped in apples and cranberries.
Both get you going. They get there differently.
Constipated, psyllium gets things moving. Loose, it firms things up. One scoop covers both.
Real dried fruit that gets things going, wherever you are. For diarrhea, use the powder.
Our core ingredients are among the most studied in nutrition science, with the published research to prove it.

24,000+ studies combined. We read the important ones so you don't have to.
Source: PubMed (pubmed.ncbi.nlm.nih.gov), the National Library of Medicine's database of biomedical literature. Counts reflect indexed publications returned for searches of "psyllium," "inulin," and "flaxseed" as of August 2026, and measure the depth of published research on each ingredient, not proof of any specific benefit.
Fiber has a sweet spot. Too little does nothing. Too much bites back.
Five grams per serving is deliberate, in the powder and in every bite. It's the dose your gut can comfortably handle, so you actually take it every day.
Our founder built Bonny. For the formulas, she recruited a ringer: an expert with 40+ years developing food and beverage products, including blockbuster household names sitting in your pantry right now. Like redacted and also redacted. The lawyers said we can't name names.
So we'll just say this: the same obsession that built the classics now goes into making your fiber work perfectly and taste like a treat. Every ratio, every fruit powder, every scoop. Fussed over. Tested. Perfected.
Great formulation means nothing without proof. So we check, then we check the checkers.
A Certificate of Authenticity from every single ingredient supplier. If they can't prove what's in the bag, it doesn't go in the blend.
Every final product goes through rigorous third-party microbial testing. Not our lab. Not our friend's lab. An independent one.
Our supply chain partners follow current Good Manufacturing Practice (cGMP) regulations enforced by the FDA.
With love. And with lab coats. Mostly lab coats, but definitely some love.
Apples, strawberries, figs, cranberries, blueberries, rhubarb, flax, cacao, monk fruit. No artificial anything.
Real reviews. Their words, not ours.
