Immune Fine Plant & Mushroom Powder boosts immunological cells that fight infections and stimulates the synthesis of immune substances like interferon. Interferon helps neutralize viruses and defends the body against harm from free radicals, stopping them from taking over healthy cells. One of our favorite combinations because not only does it have remarkable disease-prevention properties but also deliciously earthy tastes from Chaga, Lion’s Mane, Reishi, and Turkey Tail Mushrooms.
