Manufacturer statement
Mercola product page says: "Following Dr. Mercola’s belief in providing the best quality products, our Organic Lion’s Mane Mushroom Extract is tested repeatedly to ensure a clean, potent product that matches what is on the label." The label/DSLD also says: "Certified Organic by: Quality Assurance International" and shows the USDA Organic seal, but I did not verify a product-specific certification entry on the certifier’s own registry.
