MaryRuth's new Vegan Liquid Fiber uses Compound Solutions' Fibriss and OnoSweet to deliver 7g of fiber per serving without the gritty texture of traditional psyllium husk products.
MaryRuth's, the supplement brand known for liquid vitamins, launched a Vegan Liquid Fiber this week. The formula uses two proprietary ingredients from Compound Solutions: Fibriss, a baobab fiber, and OnoSweet, a fermented rice sweetener.
The product delivers up to 7 grams of fiber per serving for ages 4 and older, and 3 grams for toddlers ages 1 to 3. It is psyllium husk-free, sugar-free, and stevia-free. The texture is smooth, without the thick or gritty mouthfeel common in many fiber supplements.
Fibriss is made from organic, wild-harvested baobab fruit. It provides both soluble and insoluble fiber along with naturally occurring polyphenols. Compound Solutions said the ingredient's neutral sensory profile makes it suitable for liquid formulations where taste and texture are critical for consistent use.
OnoSweet is a patented, zero-calorie sweetener derived from fermented rice. The company said it delivers sweetness without bitterness or a lingering aftertaste, and it meets clean-label and sustainability expectations.
Meg Taylor, Director of Science and Innovation at MaryRuth's, said the brand had been looking for ingredients that could improve the user experience. "Fiber supplements have always had a reputation for being hard to take and harder to enjoy," she said. "When we found Fibriss and OnoSweet from CSI, we saw a real opportunity to flip that script."
Kyle Adams, Sales Director at Compound Solutions, said the partnership reflected the brand's approach to product development. "Meg, Jen, and the entire MaryRuth's team have always been incredibly innovative," he said. "We're proud to partner with a team that's consistently pushing the boundaries."
Jen Kavan, Director of Project Management and Product Development at MaryRuth's, noted that creating a psyllium-free, sugar-free liquid fiber that works for all ages was a difficult bar to clear. "Partnering with Kyle and the team at CSI made it possible," she said.
Compound Solutions, based in Carlsbad, California, has supplied science-backed ingredients to the supplement industry since 1998. The company's product line includes ingredients for gut health, sports nutrition, and general wellness.
