The Immune Support Formula is an exclusive combination featuring Astragalus, a potent tonifying herbal remedy prized in traditional Chinese medicine. This evidence-based formula also contains a potent blend of immune supportive polypore mushrooms including Maitake and Reishi. Maitake mushrooms have been well studied for their ability to support healthy immune function. Reishi, another important medicinal mushroom, also bolsters natural defenses.

Taken on a regular basis, the unique combination of ingredients found in the Weil Immune Support Formula may support a healthy immune system.

"For centuries, traditional medical systems of both China and Japan have used mushrooms to increase resistance to stress and promote longevity. To enhance your immunity further, I also recommend the Chinese herbal remedy Astragalus membranaceous, which has antiviral and immune-boosting effects. It's safe to take every day during cold and flu season or year-round."
Andrew Weil, M.D.
