At NOW, we are picky about our plants. We work closely with our suppliers to ensure that we’re offering the highest quality adaptogenic herbs like ashwagandha, astragalus, kava kava, rei-shi mushrooms, rhodiola, and more.
It’s not uncommon for us to reject raw materials that don’t meet our standards by testing too high for heavy metals, pesticides, and other contaminants. Our adaptogens and super herb extracts undergo rigorous quality control standards so that you can trust what is on the label is in the bottle.
Make sure to check out our NOW® Immune Renew™, which has been specifically formulated to support the immune system with standardized astragalus extract and a specialized mushroom blend!*
