Birch Bark for Immunity

Birch bark extract, standardized to not less than 60% Betulin, is produced from the outer bark of the Betula papyrifera birch tree, sourced in the U.S. from sustainably managed birch forests.

The bark is hand sorted during harvesting to ensure the botanical identity of the starting material and prevent the introduction of bark from other tree species.

Our Birch bark extract contains naturally occurring constituents Betulin, Betulin caffeates, Betulinic Acid, Lupeol and Betulinic aldehyde, in the most optimal ratio.
