Our Product

Oval, symmetrical, resistant and fierce, this potato starch is the perfect granule.

The unique size and shape of the potato starch granule make it exceptionally resistant to digestive enzymes allowing it to arrive at the colon intact. Once there, it lives out its destiny by feeding Bifidobacterium and keeping the microbiome ecosystem balanced and nourished.

Our Purpose

Over 10,000 years ago, ancestral diets were raw and rich in unripe fruits and vegetables, containing 30-50 g of resistant starch per day. Over time, modern food manufacturing methods like milling and cooking have stripped resistant starch from our diets.

Today, we’re in a nutrient-deficient state of crisis.

The average American gets only 4 g or 20% of the Suggested Dietary Target (SDT) of resistant starch from diet alone.


Resistant starch refers to all starches that remain “resistant” to digestive enzymes when they reach the large intestine. Resistant Starch Type 2 (RS2) is a native granule from an unmodified food source found in certain fruits, vegetables, and grains. It is a unique type of prebiotic dietary fiber that has been well-research for its effects on healthy digestion, IBS symptoms and proper immune system function.1

Our purpose is to close the resistant starch gap to restore human health.

Unmodified potato starch granules are exceptionally rich in RS2

Solnul™ has >60% RS2, the most concentrated form of RS2 with substantiation on the market

See why resistant starch is the Unsung Hero of Dietary Fiber.

Here's why resistant starch is crucial for supporting a healthy gut microbiome:

It’s a starch that arrives in the large intestines intact like insoluble fiber, but is fermentable like soluble fiber demonstrating the benefits of both types of fiber.

It increases healthy endogenous bacteria, like Bifidobacterium, which in turn help to modulate the immune system and support healthy digestion.

It selectively feeds Bifidobacterium, its primary degrader, that cross feeds other bacteria like Akkermansia, which helps to support gut barrier function and weight management.

It works in areas beyond the gut like metabolic health, helping to reduce insulin resistance. Its effects on kidney function are currently being studied.

Australian researchers at CSIRO have circled low resistant starch consumption as the crucial factor contributing to many of the diseases afflicting the Western world that have typically been associated with low fiber intake, even though fiber targets are met.

Dietary preferences and modern food processing methods have eliminated the vast majority of resistant starch from our diet. You would have to consume over 10,000 kcal/day to achieve the SDT from modern foods, making dietary supplementation and fortification of foods with resistant starch absolutely necessary.

The Founders

Earl and Derek McLaren are former farmers and pioneers of microbiome research. After 23 years of farming potatoes, the brothers decided to try their hand at a new venture after realizing the potential from a potato processing co-product, potato starch. Sustainable solutions come innately to farmers who have been upcycling co-products for centuries.

In 2002, they purchased a manufacturing facility and began building MSP Starch Products Inc. into a global leader in the starch industry. The business really started to take off after discovering the ancestral story and unique gut health benefits of the potato starch granule – Resistant Starch Type 2 (RS2). It took years to perfect the proprietary process of cleaning and gently drying the delicate starch granules. The outcome was Solnul™, an ingredient with the highest concentration of RS2 and only supplement-grade resistant starch on the market.

Captivated by the ancestral RS2, the brothers started down the path of clinical research light years before the industry trend to validate their belief that resistant starch could have a profound effect on the health of the microbiome. Today Solnul™ is supported by over a decade of human clinical and scientific research and employs a Chief Scientific Officer to oversee the product’s future research developments.
