Why We Chose Solnul: A Smarter, Sustainable Prebiotic

Why We Chose Solnul: A Smarter, Sustainable Prebiotic

Since we’re on a mission to make great health easier for everyone – starting with digestive health – we knew we wanted to formulate a next-level fiber drink mix that’s truly remarkable. Let’s Go Fiber+ is not the same-old fiber supplement people have choked down for decades. It’s smooth, easy to mix and not gritty like the old school ones.

A big part of the formulation process was finding clinically researched ingredients that also support our people and planet goals. One of our star ingredients? Solnul®, a next-generation resistant potato starch prebiotic that feeds beneficial gut bacteria and promotes microbial diversity.* (Organic acacia fiber is also an important part of the formula!) Read on to learn how this Certified Upcycled ingredient stands out among other fibers.

What is Solnul Fiber Supplement?

Solnul fiber supplement is a patented resistant starch made from upcycled, non-GMO potatoes. Normally when you hear the word “starch,” you think of quick-burning or simple carbs. Resistant starch like Solnul is totally different! It’s an upcycled potato starch fiber.

Unlike conventional dietary starches, Solnul resists digestion in the small intestine and travels intact to the colon – where it becomes fuel for your gut microbiota.* It blends the best of both types of dietary fiber: It arrives in the colon intact (like insoluble fiber, aka roughage) but it’s fermentable (like soluble fiber, the type that gels). Solnul is about 60% RS2 or type 2 resistant starch, a well-researched form that has numerous unique benefits.  

The fermentation process supports a balanced and diverse microbiome, a cornerstone of digestive health.*

What makes Solnul truly unique?

  • Non-GMO Project Verified
  • FODMAP-friendly certified
  • Beyond Celiac Gluten-Free certified
  • Glyphosate residue-free
  • Kosher
  • Certified Upcycled and sustainably produced
  • Tasteless, odorless and gentle on digestion*
  • Clinically studied prebiotic has been the subject of peer-reviewed human studies*

The Role of Microbial Diversity in Gut Health*

Gut microbial diversity is one of the strongest markers of a healthy digestive system. A richer, more balanced microbiome can help support:

  • Digestive regularity*
  • Comfort and reduced bloating*
  • Gut lining integrity and immune resilience*

In studies, Solnul has been shown to increase populations of Bifidobacterium, a genus of beneficial bacteria linked to digestive support and microbial balance.*

Benefits of Solnul Resistant Potato Starch

Solnul’s effectiveness is backed by peer-reviewed clinical research, an important distinction when choosing ingredients. Studies show that consistent daily use of Solnul may:

  • Prebiotic for healthy bowel movements*
  • Encourage the growth of beneficial gut bacteria*
  • Support gut lining barrier function*
  • Fiber for gut barrier function*

These benefits make Solnul a standout for those seeking evidence-based digestive support, particularly when used alongside postbiotics and probiotics.*

Why We Chose Solnul for Let’s Go Fiber+

We chose Solnul® because it meets the high standards we set for all our ingredients: effective, sustainable and science-backed. Here’s how Solnul aligns with our values:

Clinically Studied Prebiotic: Human trials support digestive and microbiome benefits*

Sustainable: Upcycled potato starch fiber reduces agricultural waste

Clean-Label Friendly: Non-GMO, allergen-free, odorless and flavorless

Gut-Friendly: Resists digestion to nourish beneficial bacteria*

Each serving of Let’s Go Fiber+ delivers 3.9 grams of Solnul and 5 grams of total dietary fiber, making it a good source of fiber. Since 95% of people fall short on fiber, this is an easy way to boost daily intake.

Sustainable Gut Health Solution

Solnul isn’t just beneficial for your digestive system; it’s also good for the planet. Using upcycled potatoes helps reduce food waste and conserve resources, aligning with our commitment to sustainable wellness.

If you’ve ever peeled and cut raw potatoes, you know how they leave a white, sticky starch behind on the knife and cutting board. A non-GMO potato fiber, Solnul makes use of that starch on a larger scale, collecting the starchy water produced by in industrial potato factories, dehydrating it and turning it into a powerful gut health ingredient! This process keeps food waste out of landfills, helping the planet, and creating a unique ingredient your gut craves.*
