Other Names: Grifola frondos

The maitake mushroom, also known as Grifola frondos, is a well-known mushroom and adapotgen that is renowned for its immune system supporting properties. Additionally, maitake is known for supporting biological processes that optimizes pH and helps the body respond in a healthy manner to stress. By promoting adequate interferon and interleukin levels in the body, two primary immune system regulators, maitake also supports healthy skin by supporting the immune system’s ability to naturally combat harmful invaders.

Maitake has also been shown through research to be useful at promoting the body’s ability to naturally protect itself from oxidative stress and free radicals. It supports natural defenses that protect cells in the body. Furthermore, this extract has the ability to support cellular health, which helps the body combat harmful toxins that could cause cell death. Research suggests that it also promotes natural defenses that help protect the body. It has the ability to support proper circulatory system function as well, which is essential for healthy cholesterol and blood pressure levels already in the healthy range.

The maitake mushroom extract is very helpful at supporting the immune system because it is an excellent source of antioxidants. In addition, this particular extract also contains proteins, minerals, vitamins, amino acids, fiber and carbohydrates that promote cellular health, which supports clear and healthy skin. As the body needs rich sources of healthy nutrients, taking the maitake mushroom extract can support overall health.
