How can something so TINY make such a BIG DIFFERENCE?

How it works + -

The Sugar Shift® team of carefully selected bacterial strains works together in harmony to transform excess sugars—such as glucose and fructose—into mannitol, a powerful free radical scavenger with unique health benefits. This natural conversion reduces the burden of sugar spikes in the bloodstream while simultaneously producing mannitol, which acts as a prebiotic to feed beneficial microbes and promote a more diverse, resilient microbiome.


Mannitol is not metabolized by your body in the same way as glucose or fructose. Instead, it nourishes gut health before being safely excreted in the urine. This dual-action process supports healthier sugar metabolism and contributes to overall gut health, making Sugar Shift® a truly innovative approach to managing the modern challenges of sugar-heavy diets.


What sets Sugar Shift® apart is its targeted team of probiotic strains—a thoughtfully assembled guild designed to restore balance within the microbiome. It’s not just another probiotic; it’s the first of its kind, a focused, natural solution for supporting your metabolic and gut health.

Why we created Sugar Shift® + -

Our cumulative lifestyle choices (unavoidable and intentional) affect the state of everyone’s microbiome. Everything that goes into the body influences our health trajectory. Balancing the bacteria in the gut benefits all of the systems of the body, especially immunity and brain function. Once the gut’s harmony is disrupted it’s difficult to re-establish balance.

We believe that sugar (glucose and fructose) is a huge problem in the Standard American Diet talking a toll on our microbiome diversity and our overall health. These sugars are hidden in many processed foods and are difficult to avoid completely. Fructose is especially challenging to our overall metabolic health and is a key driver of metabolic disease and imbalance in the microbiome. Our revolutionary probiotics solved this problem in an innovative way.

Why it’s revolutionary + -

Our goal was to design a life changing probiotic to help people, like Martha's husband John, feel better every day. Sugar Shift's patented formula creates the right team of probiotic bacteria to shift the way the body metabolizes sugar and restore balance and diversity to the gut. When taken daily, Sugar Shift supports the body's ability to digest and deliver nutrients, detoxify, produce short chain fatty acids, increase energy and more.
