Source Naturals Mushroom Immune Defense

Shop for Source Naturals


Mushrooms have been revered since ancient times and traditionally used to support general well-being and immune system health.* Source Naturals Mushroom Immune Defense™ provides a blend of mushroom mycelia and extracts from over a dozen health-supportive species, including the well studied shiitake, reishi, maitake, turkey tail, almond portabella and cordyceps.

Preliminary studies suggest that mushrooms such as maitake and shiitake may support the healthy activity of natural killer (NK) cells, T-cells, macrophages and cytokines, which are all key components of a healthy immune system.* By carefully combining mushroom mycelia and extracts, Source Naturals Mushroom Immune Defense™ offers a complete and robust mushroom product formulated to provide immune system support.
