Frequently Asked Questions

What is ISOVive? The ISOVive starter Guide

What is ISOVive Prebiotic Nectar?

ISOVive is a naturally fermented, zero calorie, prebiotic soluble fiber designed by nature to feed beneficial bacteria in your digestive system. Unlike other prebiotics that can cause gas, bloating and other unwanted side effects, ISOVive works to reduce these to help you feel comfortable again.

What are the ingredients in ISOVive?

ISOVive is created by a natural fermentation process starting with sugar, maltose and trace nutrients such as yeast, calcium, and magnesium. The fermentation process completely consumes those ingredients and all that is left is a fermented prebiotic called MIMO™ (maltosyl-iso-malto-oligosaccharides). This is a non-digestible soluble fiber that feeds the beneficial bacteria in your digestive tract. MIMO is the same natural prebiotic found in traditionally fermented sourdough bread. And it is completely gluten free! Rather than having to eat an entire loaf of bread, you get the same benefits in just ¼ teaspoon of delicious nectar.

What is the difference between a prebiotic and probiotic?

PRObiotics are the beneficial live bacteria that reside in your gut. PREbiotics are non-digestible soluble fibers that act as food for healthful bacteria (i.e. food for PRObiotics). We need to feed these beneficial bacteria to maximize health and wellness.

What makes ISOVive so unique from other prebiotics?

Prebiotics are not interchangeable. Different gut bacteria require different food, and some require the fermented prebiotic, MIMO™. ISOVive is the only prebiotic supplement that contains MIMO. Other prebiotics (e.g. FOS, Inulin) require a much higher dose, can cause significant gas and bloating and have been found to make heartburn worse. MIMO avoids these unpleasant side effects.

Do I need ISOVive if I already eat a natural, healthy diet or take other prebiotics?

Since the dawn of agriculture, our microbiome evolved around two sources of prebiotic soluble fiber 1) the kind found in certain plants and 2) the kind found in traditionally fermented vegetables and sourdough bread made from heirloom wheat. Fermentation used to be one of the few ways to preserve food, but with refrigeration most people now do not eat fermented foods, or if they do it’s just in small amounts. As a result, a critical type of prebiotic soluble fiber is missing from the diet. ISOVive is the only prebiotic supplement that supplies this prebiotic. To get the same benefit from food, you would need to eat an entire loaf of sourdough bread made from ancient wheat (if you could even find it) every single day. ISOVive provides that same benefit with just ¼ teaspoon of delicious lightly sweet nectar.

How do I take ISOVive

Do I need to take ISOVive every day?

Yes. ISOVive is food for beneficial bacteria in your digestive tract. They need to be fed daily just as you need to eat food daily. Therefore, ISOVive is something to be taken daily on an ongoing basis.

What time of day should I take ISOVive? And should I take ISOVive with or without food?

For best results with heartburn/acid reflux, we recommend sipping ISOVive full strength as the last thing you swallow at night before lying down for bed, after brushing your teeth. Otherwise, for overall, digestive health, you can take any time of day with or without food.

The amount in each sachet is so small, is that really enough?

ISOVive is super concentrated. More is not always better. We have tested various doses and have found this small amount to be most effective for overall digestive health. Also, each sachet is filled with a little extra ISOVive so you don’t have to worry about getting every last drop.

Can ISOVive be taken with probiotics?

It’s actually not necessary to take a probiotic. The latest research shows that prebiotics are more important and more effective for digestive health than probiotics. If you do continue to take a probiotic just make sure to take ISOVive as the last thing you swallow at night before lying down for bed.

Can ISOVive be used with medications or other supplements?

ISOVive can be used safely with other dietary supplements and medications. We cannot give medical advice, and if you have questions about your specific medications, you should speak to your healthcare professional.

ISOVive Safety and Manufacturing

Are there any known side effects?

Unlike other prebiotics which can cause significant gas, bloating and other digestive discomfort, most ISOVive users generally find none of these side effects. For some, depending on your own personal microbiome, it is possible that as your system adjusts you might experience some digestive rumbling, gas or loose stool for the first few days on the product. If this does occur, it should subside within a few days. After that, most people experience better digestion than ever before. If for any reason discomfort persists for more than a few days, please discontinue use of the product.

Where is ISOVive made?

ISOVive is made in Belgium and packaged in the US. ISOVive is manufactured under FDA Current Good Manufacturing Practices (cGMPs). ISOVive is made with a controlled specific and reproducible bacterial fermentation (similar to how sauerkraut and kim chi are traditionally made). The final product is triple tested for purity. Unlike most dietary supplements, we also use scientifically advanced analytical methods to determine the detailed chemical composition of the product. This ensures that each batch is consistently made, maintains the highest quality standards and is actually what is listed on the label.

Does ISOVive contain allergens?

ISOVive is gluten free, wheat free, soy free, dairy free, vegan and does not contain genetically modified ingredients. Please note the packaging facility may also handle food allergens such as eggs, fish, gluten, milk, peanuts, shellfish, soy & tree nuts. ISOVive is packaged under current Good Manufacturing Practices (cGMP). The equipment is thoroughly cleaned between each use.

Is ISOVive safe?

YES! ISOVive is a naturally fermented prebiotic that has been found in the food supply for thousands of years. There are hundreds of scientific studies documenting the safety (and health benefits) of prebiotics. ISOVive has been documented by a panel of scientific experts as Generally Recognized As Safe (GRAS) under FDA guidelines.
