Mushroom Optimizer™ is an advanced blend of seven species of mushrooms that are grown on organic brown rice. The species of mushrooms are selected for their ability to complement each other in their support of the immune system, endurance, and cell function.

Mushroom Optimizer™ consists of Folagen™, biologically active folates. These folates are formed through the addition of folic acid to certain mushrooms’ growth medium. Mushroom Optimizer™ combines with various polysaccharides, to support immune function, enhance colon health, protect cells, and increase energy levels.

Mushroom Optimizer™ also contains the very large maitake mushroom that can be found in the mountains of Northeastern Japan and in a few regions of North America and Europe. Maitake has a unique taste and is known for its medicinal benefits.
