VitaFiber® (Isomalto-Oligosaccharide — BioNeutra)

Evidence Level
Limited
1 Clinical Trial
3 Documented Benefits
2/5 Evidence Score

VitaFiber® is an isomalto-oligosaccharide (IMO) from BioNeutra, a fiber and low-glycemic sweetener made from starch. It provides prebiotic fiber that feeds beneficial gut bacteria while adding gentle sweetness, and is used in low-sugar foods and supplements.

Studied Dose Used as a fiber and sweetener; a few grams per serving.
Active Compound Isomalto-oligosaccharide (IMO), a partially digestible prebiotic fiber and low-glycemic bulking sweetener.

Benefits

Prebiotic fiber

IMO is fermented by beneficial gut bacteria, supporting a healthier microbiome and the production of short-chain fatty acids.

Supported by Trial 1

Digestive support

As a soluble fiber, it supports regularity and a balanced gut environment.

Supported by Trial 1

Low-glycemic sweetness

IMO adds bulk and mild sweetness with a lower glycemic impact than sugar, useful in reduced-sugar products.

Mechanism of action

1

Selective fermentation

Gut bacteria ferment IMO into short-chain fatty acids that nourish the colon lining and favor beneficial species.

2

Partial digestion

Only part of IMO is digested for energy, while the rest acts as fermentable fiber, giving it a fiber-and-sweetener dual role.

Clinical trials

1
IMO Fiber and Gut Microbiota — Study
PubMed

Head-to-head crossover comparing three fibers (inulin, VitaFiber IMO, and a fiber blend) at 15 g/day, profiling gut microbial and immune responses. (Tan et al. 2023, Gut Microbes)

Healthy adult women (crossover).

In this crossover in healthy women, IMO produced some specific shifts in microbial and immune markers, but its effects were less pronounced than inulin, which alone showed the SCFA-producing-taxa signature; the authors call for larger studies.

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated as a fiber.
Mild gas or bloating can occur as intake rises.
Provides some digestible carbohydrate; account for it if managing blood sugar.

Important Drug interactions

Diabetes medication — IMO has some digestible carbohydrate; monitor blood sugar.
Introduce slowly if you have IBS.
Tell your doctor if you have a serious digestive condition.
