“IMO” is an acronym for isomalto-oligosaccharide which is a mixture of short-chain carbohydrates that have digestion-resistant properties. The raw material used for producing IMO is starch, which is enzymatically converted into a mixture of isomaltooligosaccharides. VitaFiber™ IMO is naturally made with non-GMO tapioca starch using a proprietary and patented process.

Isomaltooligosaccharide, including VitaFiber™ IMO, is a proven prebiotic as shown in number of studies. In fact, the number of available publications about prebiotic effect of IMO is greater than any of its other health benefits, including in our own conducted Human Clinical study. A randomized, double-blind, placebo-controlled clinical trial involving 60 healthy adults was carried out to determine the safety and health benefits of VitaFiber™ IMO. Subjects were randomized to receive either a low dose of VitaFiber™ IMO (36g/day), a high dose of VitaFiber™ IMO (54g/day) or a placebo for 4 weeks. VitaFiber™ IMO administration at 36g/day was found to significantly increase the fecal counts of bifidobacteria and lactobacillus. Subjects in the VitaFiber™ IMO low-dose group also showed a significant reduction in frequency of hard stools, indicating laxative benefits of the product (BioNeutra, 2012, unpublished study).

Regularly using VitaFiber™ IMO can help you maintain effective digestive health because it is a good source of prebiotics and digestive fiber that are both necessary for maintaining good gut health. Most sweeteners and sugar alternatives currently on the market do not offers these benefits.

VitaFiber™ IMO actually tastes great! Many of the sweeteners and sugar alternatives on the market have a strong flavor or a weird aftertaste which isn’t pleasant and doesn’t feel natural. VitaFiber™ IMO, on the other hand, doesn’t have these issues considering has a natural and mild flavour that is really enjoyable on the pallet. VitaFiber™ IMO can be described as a mild honey.

As well, VitaFiber™ IMO is sugar-free, low-calorie, Non-GMO Project Verified, vegan, gluten-free, dairy-free, has no artificial colors, flavors or preservatives, and it’s halal and kosher. That is a lot of benefits! 

To maintain a healthy digestive system the average adult needs to consume at least 45 grams of digestive fiber per day or 10 to 15 grams per serving. Therefore we recommend consuming no more than 75 grams of VitaFiber™ IMO syrup and 56 grams of VitaFiber™ IMO powder per day day.

According to the published literature, isomaltooligosaccharide, including VitaFiber™ IMO, is a mixture of digestion-resistant carbohydrate which has low caloric value and also has low glycemic index. However, at this time there aren’t any human clinical studies available regarding its impact upon the blood glucose levels.

The fiber listed on our labels is dietary fiber (or dietary fibre), so you can subtract it from the total carbohydrates to calculate your net carbs.

We do not recommend converting IMO powder into IMO syrup. Not only is it not cost effective, but the quality will never be the same. With that said, VitaFiber™ IMO syrup contains approximately 25% water, therefore you can try heating a 3:1 mixture of powder to water for 10 to 20 seconds in the microwave. Stir for a minute or two and let sit for 15 to 30 minutes. This syrup will likely not be clear like the original IMO syrup.

No, it’s not necessary. VitaFiber™ IMO is best stored at room temperature (68F = 20C). It is fine to refrigerate it if that is your personal preference, but colder temperatures will increase the syrup’s viscosity.
