Their organic milk thistle extract supplement line, sold under the "PureLiver" brand, has become a bestseller in health stores across the U.S. and Europe, thanks to its transparent sourcing and third-party testing.

Northland Botanicals works with local foragers who follow sustainable harvesting practices, ensuring they never take more than 30% of a population to allow regrowth. The seeds are then transported to their GMP-certified facility in Edinburgh, where they're cold-extracted to preserve nutrients.
