5 Time Clinically tested Mulberry Extract

Finally Something That Works

Our mulberry extract with concentrated DNJ has been clinically tested five times with people and shown to moderate after meal blood glucose spikes due to carbs & sugars by a group average of 40%.

When taken in advance of a meal StayLo gets ahead of the food you eat to reduce the enzyme activity that sends sugar into the bloodstream.

By bypassing the bloodstream StayLo is repeatable each and every meal with no side effects.


After-meal blood sugar levels from a single healthy individual. Results will vary.

Safe, Repeatable, & Water Extracted DNJ

What is StayLo

Long-known leaf extract concentrated 50x for more power using the latest water extraction technology.

StayLo contains concentrated mulberry iminosugars, including 1-deoxynojirimycin (DNJ) that have long been used but never available before in an isolated extraction.  Iminosugars look like glucose to the body and temporarily reduce the absorption of carbs & sugar after a meal without needing to enter the bloodstream. The excess glucose is turned into prebiotics for the microbiome.

“This is a revolutionary product. I’ve been looking for something like this for years.”

Steven Willey, M.D.

This is the first non-prescription, clinically studied  supplement that produces a profound and immediate reduction in the impact of complex carbohydrates and sucrose in healthy people. Importantly, StayLo has a straightforward mechanism of action by decreasing the activity of the enzymes that digest carbohydrates including sucrose.

Consistently moderating carbohydrate impact at mealtime supports healthy blood sugar levels, resulting in a cascade of metabolic improvements including balanced insulin sensitivity.

Amazingly StayLo promotes these benefits without a change of diet when used as directed.”*

Dr. Willey does not provide medical advice to anyone except his patients of course.  His opinion is based on a review of clinical studies and scientific literature.
