What is it?

Sunfiber is an all-natural fiber derived from the Indian guar gum bean.

What does it do?

As sunfiber passes through the intestines, it ferments into short-chain fatty acids that help to cultivate good bacteria in the gut and support intestinal health.

Why we chose it

Sunfiber is water soluble and low GI, meaning it doesn’t disrupt vitamin and mineral absorption the same way that most fibers do. It also doesn’t cause any of the gas, bloating or digestive discomfort commonly associated with high-fibers sources.

Why not a generic Prebiotic?

Our clinically-backed prebiotic is one of the few fibers in the world that doesn’t result in excess gas or bloating.


Key Findings

Humans taking Sunfiber® showed a notable increase in friendly gut bacteria after 12 weeks, compared to the placebo group.
