Resistant Starch: The Exceptional Prebiotic

Many resistant starches have a prebiotic effect, but not all prebiotics contain resistant starch. See how Solnul™ stacks up against other prebiotics in its category.

It’s Food
Solnul™ is a native prebiotic RS2 from an unmodified food source. Other prebiotics can be made from sources with no history of human consumption like straw.

It’s Ancestral
Resistant starch has been a part of human diets for over 10,000 years, making it one of the most widely consumed prebiotics in human history.

It’s Low Dose RS2
Clinically-proven at doses as low as 3.5 g, Solnul™ is the first low dose resistant starch, effective at 1/10 of the previously documented dosage.

It’s FODMAP Friendly
Low FODMAP diets can improve IBSrelated symptoms but can also starve the gut by reducing the abundance of prebiotic fiber needed for GI healing. Contrary to many prebiotic fibers, Solnul™ is slow to ferment, well-tolerated and FODMAP Friendly approved.

It’s Multi-Functional

While other prebiotics can have a singular mechanism, Solnul™ has a triple-action effect on IBS related symptoms with a reduction in daily occurrences of gas, constipation and diarrhea, promoting regularity.

It’s Ambilateral
Most prebiotics fall into either soluble or insoluble fiber categories. Resistant starch is unique in that it acts like both; it arrives in the large intestines intact like insoluble fiber,
but is completely fermentable like soluble fiber.

It’s Clinically-Proven
Human behavior and physiology can’t be modeled in test tubes. That’s why Solnul™ is studied in human clinical trials instead of in vitro, allowing for substantiated label claims.

It’s Seamless
Solnul™’s neutral color, flavor and mouthfeel makes it undetectable in supplement and functional foods. Benefits without the sweet taste.

Why Solnul™ is an Unrivaled Prebiotic

Solnul™ is an ancestral prebiotic ingredient that selectively feeds the native beneficial bacteria that support optimal digestion and GI health.

  • Low Dose RS2:

Produces a prebiotic effect, increasing the abundance of Bifidobacterium at 1/10 of the previously documented dosage.

3.5 g Solnul™ Standard Dose: +350% Bifidobacterium Increase.

Bifidobacteria are the beneficial bacteria native to the gut that have been wellresearched
for their effects on healthy digestion, IBS symptoms and proper immune system function.

  • Multi-Functional + GI Restorative

Triple action effect on IBS related symptoms, simultaneously improving daily gas, constipation and diarrhea, normalizing stool consistency.

7 g Solnul™ Restorative Dose:

  • -17% Daily Gas
  • -66% Daily Constipation
  • -59% Daily Diarrhea Reduction

Contrary to many prebiotic fibers, Solnul™ is well-tolerated, meaning it does not promote gas or digestive upset and is suitable for special diets like low FODMAP, which is crucial for IBS sufferers who need fiber for GI healing.

  • Superior Quality

​​​​​​​Made by industry experts through a proprietary process to deliver a guaranteed >60% RS2. Our superior quality allows for consistent health outcomes for desired label claims.

Solnul™ has >60% RS2
Resistant Starch Type 2 (RS2) is a native granule from an unmodified food source. Solnul™ is RS2 from raw potato.

Resistant starch is the real gold – it promotes gut-wall integrity, healthy digestion and optimal immune function.

 

Solnul™ Delivers on Top Prebiotic Benefits Consumers Seek

Gut Health/Digestion

Through human microbiome research, Solnul™ has substantiated several structure/function claims that promote gut health.

Immunity Health

At 3.5 g daily, Solnul™ significantly increases Bifidobacterium by 350%, which in turn help to modulate and support the immune system function.

Microbiome Health

Solnul™ helps to optimize the microbial balance in the GI tract. It can also be paired with a probiotic for a pre/pro combination; a key characteristic consumers look for when purchasing a prebiotic product.

Source of Fiber

Ambilateral fiber is vital to supporting a healthy microbiome. Solnul™ is made up of >63% ambilateral fiber from a whole food source and is considered a dietary fiber in many regulatory regions.

Regularity

As low as 3.5 g, Solnul™ not only promotes but maintains bowel regularity and normal bowel movements while being well-tolerated and Low FODMAP.

Technical Details & Test Data

Resistant Starch: The Unsung Hero of Dietary Fiber

Traditionally, total dietary fiber has been broadly classified as insoluble and soluble
fiber based on the AOAC Official Methods of Analysis.

  • Insoluble Fibes: Is non-fermentable, or poorly fermented ‘roughage’ that helps improve stool formation, laxation and blood glucose control.
  • Soluble Fiber: Is highly fermentable and readily utilized by the gut microbiome supporting the growth of beneficial bacteria and improved glycemic response.
  • While most constituents of fibers would fit into either of these categories, resistant starch is unique in that it acts like both.
  • It’s a starch that arrives in the large intestines intact like insoluble fiber, but is completely fermentable like soluble fiber demonstrating the benefits of both types of fiber.

Total Dietary Fiber: 

  • Insoluble, Non-Fermentable Fiber
  • Resistant Starch: Insoluble, Fermentable Fiber
  • Soluble, Fermentable Fiber

Since the AOAC Methods of Analysis have been adopted as the de facto operational definition of dietary fiber, they are the gold standards for nutritional labeling purposes even though it doesn’t always highlight some of the more unique types of dietary fiber, like resistant starch.

Given its ambilateral physiological effects and prebiotic support for the microbiome, here’s why resistant starch deserves special consideration:

  • Australians eat the most fiber out of any other western country, and although only slightly below the fiber target, still suffer from diseases affiliated with low fiber intake.
  • The typical western diet provides only 20% of the resistant starch Suggested Dietary Target (20 g).
  • Low resistant starch intake can be linked to diseases such as metabolic health, cholesterol, kidney and cancer.
  • Since consumer understanding of resistant starch is blanketed under the term of total dietary fiber and resistant starch isn’t commonly found in all food, intake from diet alone will continue to be low.

Since the regulatory requirements for dietary fiber labeling are arbitrary due to its reliance on methodology, we need to work within the parameters and use creative forms of communication to spread the resistant starch message.

The Australian Ministry of Health has done exactly this by recommending an allowance for resistant starch as part of the dietary fiber intake and by establishing a resistant
starch 20 g SDT for chronic disease prevention.
Like many valuable nutrients void in modern diets, it’s only a matter of time before the dietary fiber definition is updated to include all constituents, better showcasing the diversity within fibers for optimum health and revealing the real heroes like resistant starch.

Comparison of Solnul™ with other Prebiotics

It’s a Valuable Nutrient

Australian researchers have identified a resistant starch Suggested Dietary Target (SDT) of 20 g to achieve optimum bowel health and improved health outcomes. Resistant starch is the only prebiotic with dietary targets separate from fiber.

Choosing the right prebiotic ingredient will not only strengthen a formulation, the claims on package and pique consumer interest but encourage consumers to take action. Solnul™ Prebiotic RS2 is your all-in-one digestive health solution.

Today, we’re in a nutrient-deficient state of crisis. The average American gets only 4 g per day or 20% of the Suggested Dietary Target (SDT) of resistant starch from diet alone.

Our purpose is to bridge the gap between ancestral and modern diets to restore human health. We do this by offering a high-quality RS2 ingredient, which raises the bar for prebiotic and resistant starch categories.
While our diets are falling short of the resistant starch SDT, we’re able to provide a fortification solution that is both convenient and effective.
