Product Notes:

The human stomach, small intestine, and colon harbor a complex ecosystem of hundreds of different species of microorganisms, including both good" bacteria which can help the digestive and immune systems, and "bad" microbiota which can impede and overtax them if they become overabundant.

Many factors such as alcohol, dietary changes, medications, stress, and even aging can lead to dysbiosis, or an imbalance in the ratio of the different kinds of gut flora -- resulting in symptoms such as upset stomach, diarrhea, constipation, fatigue, or difficulty concentrating. But that can be prevented or even reversed with the help of a prebiotic like MS Prebiotic, which supplies resistant starch - dietary fibres which we can't digest, but serve as nutrients to help the healthy bacteria flourish again. This not only helps promote regularity, but also works to regulate blood glucose levels, reduce insulin resistance, and provide a glucose-independent source of energy (by increasing the production of a short chain fatty acid called Butyrate).

MSPrebiotics was the subject of a human clinical trial led by a clinical microbiologist at the University of Manitoba's St. Boniface Research Centre, which found that resistant starch significantly increased the amount of good bacteria (specifically, Bifidobacterium) in both elderly and middle aged test subjects compared to the placebo groups, and also significantly decreased the amount of Proteobacteria (Escherichia coli/Shigella) the elderly test group was suffering from, which reduced their constipation.


MSPrebiotic: Helping you feed your microbiome. The ketogenic diet can in some cases have a negative impact on the health of the gut microbiome, the complex ecosystem of healthy bacteria that plays a role in many aspects of our health. This is because the microbiome relies on prebiotic fibre for food and most prebiotics are found in foods that are typically avoided in the ketogenic diet. Very high in fibre, MSPrebiotic is keto-compatible and can help keep you from starving your microbiome.

Don't forget your Butyrate: Butyrate represents an important source of energy while on the ketogenic diet and this molecule also plays a crucial role in other aspects of our normal health. Fortunately, MSPrebiotic is fermented by healthy bacteria in the gut to produce butyrate, providing a natural source of this essential nutrient.

Is MSPrebiotic just Potato Starch?

MSPrebiotic is a type 2 prebiotic resistant starch (RS2) from potatoes designed specifically to be safely consumed uncooked as a supplement. Conventional grocery store potato starches are meant to be consumed after cooking (they're usually used as a thickener in flours, soups, stews, gravy). Cooking kills off potentially harmful pathogens but it also degrades the prebiotic fibre properties. MSPrebiotic has a very high fibre level, while some cooking/baking potato starches are not significant sources of fibre. Potato starches used for cooking can in theory be consumed raw, but they aren't intended for such purposes, and like other raw foods there is a risk of food-borne illnesses. MSPrebiotic is produced via a proprietary process ensuring high fibre content and safety for use as a nutritional supplement.

MSPrebiotic is made in Manitoba, Canada.

MSPrebiotic Ingredients:

Each 10 g serving contains:

10 g of Solanum tuberosum extract, providing 7 g of fibre (including 6 grams of insoluble fibre).

Non-GMO, caffeine-free, gluten-free, and manufactured and packaged in a certified gluten-free facility. FODMAP-friendly and suitable for vegan diets.

Suggested Usage:

You can add flavourless MSPrebiotic potato starch powder to any cold or room-temperature beverage, including juice, water, smoothies, or shakes. Please note, it should not be added to hot beverages, since it loses effectiveness when heated to 60°C or above.

MSPrebiotic will not actually dissolve in liquids, but it can be suspended in them, by stirring it into water or juice and consuming it immediately afterwards. Or to prevent settling, it can be added to something thicker like a shake or smoothie, which can then be consumed at a slower pace, at your convenience.

For best results, the ratio for mixing it with a liquid would be 10 grams of MSPrebiotic (= 1 Tablespoon; one level scoop) to 80 ml of liquid, followed by another 40 ml of liquid alone. It can also be added to foods like granola cereals, oatmeal (after it's cooled off), yogurt, savory dips, or salad dressings.

Introducing large amounts of prebiotics to your diet too quickly can be associated with bloating, gas, and discomfort, however, so it is recommended that you begin gradually: starting with a dose of one teaspoon (or about 3.5 g: the line indicated 1/3rd of the way up on the enclosed scoop) daily for the first week, then moving either to a two-teaspoon dose daily during the second week, or right to a full scoop (= 1 Tablespoon) daily.

Depending upon the desired effect, you may continue to gradually increase your daily dose from there, but supplementing with more than 30 grams/scoops of MSPrebiotic a day is not recommended.

For best results, MSPrebiotic should be consumed every day.

Store in a cool, dry place.


Keep MS-Prebiotic out of reach of children. Consult a healthcare practitioner before using this product if you are pregnant or breastfeeding. Ensure that you adequately hydrate before, during, and after exercise.

MSPrebiotic Side Effects: Evaluation in a clinical setting has demonstrated that MSPrebiotic is very well- tolerated and causes no side effects. However, some users might experience increased gas and bloating during the first week or so if you start with the full 10 gram daily standard dose, so as noted above, it is recommended that you start with one-third of that.
