The Primary Benefit Is: Immune Function Support

Immune function support means keeping normal immune responses and overall wellness going. This product provides a seven-mushroom fermented blend made in the United States using solid state fermentation on organic oats as the culture medium, yielding a whole-food mushroom and mycelium complex.

This formulation is crafted as an organic, gluten-free and non-GMO fermented mushroom complex designed to be using whole-food sources rather than isolated extracts.

How Does This Support Immune Function?

The mix of fermented mushrooms helps support normal immune function through its diverse bioactive components in a whole-food matrix. This approach aligns with EFSA-style statements about maintaining normal immune system activity and antioxidant support within a balanced diet.

This product isn't meant to diagnose, treat, cure, or prevent any disease.
