Betulin, the substance in birch bark that gives the bark its beautiful white color, is one of the most actively researched phytochemicals (1,2)


Unlike other natural extracts with unproven health claims and vague notion of biological mechanisms, betulin, an active ingredient of BETULEX™, is a truly unique gift from nature with specific and beneficial properties

Betulin prevents virus spread by suppressing lipid production inside infected cells.  Without these lipids as part of their coating, viruses are no longer functional and cannot propagate* (3,4,5)

Group 10.png

By acting on the same molecular target (a protein called SREBP), betulin also leads to reduced cholesterol - a major step forward for long-term metabolic health (4)

How should I take BETULEX™?


To increase betulin's absorption in the body, take it with food containing a healthy source of fat


Take 1 BETULEX™ capsule daily as an optimal prevention measure.


Take 2-3 capsules daily during high-risk times, such as flu season or viral outbreaks.


The basics of BETULEX™

Group 54.png


BETULEX™ is manufactured in FDA-compliant and registered facilities. Primary extraction is performed by proprietary eco-friendly process from the outer bark of Siberian birch trees.
