Quality ingredients make a better formula. Like our non-GMO-verified pau d’arco bark. Its active components, including lapachol, provide important properties for immune health. Research indicates that pau d’arco extract seems to help prevent microbes from getting the oxygen and energy they need to thrive.
Harvesting pau d’arco is complicated as these trees are a protected species in Brazil. Nature’s Sunshine works with experienced partners with whom we have done business for more than 20 years. They ensure that the inner bark material—a by-product from legal wood harvest—is carefully collected and legally shipped.
