4 Functional Fibers
Made with Real Food

Made with Real Food
We combine real food ingredients for a fiber powder you can feel good about.
Different fibers have distinct roles, which is why we blend four functional sources to support gut and digestive wellness. Many Americans fall well short of the recommended fiber daily intake, averaging around 10–15g per day, about half of what’s needed. For instance, the USDA recommends 25 g per day for women (up to age 50) and 38 g/day for men (up to age 50), with slightly lower targets for older adults. This blend helps you close that gap.
Our quality assurance process for our nutritional and supplement products begins with collecting, from our suppliers, Certificates of Analysis (COAs) for our ingredients. We then retest the final product blend. We share our COAs because we believe the results are worth sharing.

Our formula delivers both fiber types for a balanced digestive effect. Soluble fibers ferment in the gut, nourishing beneficial bacteria and supporting digestion, while insoluble fibers add bulk and support regularity.
We include prebiotic fibers, fructooligosaccharides, inulin, and hydrolyzed guar fiber, that feed beneficial gut bacteria, helping to support a balanced microbiome. This kind of functional support goes beyond traditional fiber.
Crafted with familiar, real ingredients, no unnecessary fillers, and no natural or artificial flavors.

"I can’t decide if it’s helping or not. I guess i need to use it longer. It doesn’t really have a strong flavor. I drink it just with my water in the morning."
"Love this product! Every other morning while I take my daily vitamins and drink my electrolytes I make sure to include the fiber to ensure it takes effect all day. My bowel movements are regular. We really love that it’s not grainy and no weird textures. We will definitely keep buying this as long as we can."
"This is an easy way to help hit fiber goals! I either dink it mixed in water, or sometimes I add it to electrolytes. I use a frother to mix it and it mixes well. Will definitely add this to list of supplements to keep on hand. Great source of fiber!"
"This fiber powder has been great! My husband adds it to his water bottle everyday, while I add it to my daily protein shake. It is very versatile and easy to use. We’re happy to be using an all natural fiber product that works! We don’t think you’ll be disappointed."
"I blend it in with my electrolytes and sip on it all day. There’s zero taste. When I’m consistent I’ve noticed a difference in my regularity. Definitely an easy way to add more fiber to my diet."
"I'm sad to say I could not get down 1 glass of this. I wanted to love it. Maybe ill start with it in juice or mixed into food. I just haven't been able to figure it out yet."
"Definitely helps keep you regular. I also add to my kids smoothies. Everyone can benefit from more fiber, especially teens who don’t have the best diets."
"Love adding to my daily drink on days I feel like I need more fiber or haven’t had enough fruits and veggies."
