Mushroom Defense Ingredients

Mushroom Defense Ingredients

Mushroom Defense contains all of the following ingredients:

  • 266mg of cordyceps sinesis powder (mycelium)
  • 266mg of reishi mushroom extract
  • 266mg of shiitake mushroom extract
  • 266mg of lion’s mane
  • 266mg of a proprietary blend containing maitake mushroom extract, turkey tail extract, chaga mushroom extract, royal sun agaricus extract, white button mushroom extract, and black fungus extract

Scientific Evidence for Mushroom Defense

Mushroom Defense has not been studied in any type of lab or clinical setting. However, the individual ingredients inside the formula have been studied.

The sales page for Mushroom Defense links to 20 studies verifying the benefits of the mushroom extracts inside the formula.

They cite this study, for example, that shows mushrooms are rich with vitamins B1, B2, B12, C, D, E, and selenium.

They also cite this double-blind, placebo-controlled trial on mice that showed cordyceps mushroom extract increased endurance by 30% to 73%, and this study showing that cordyceps mushrooms have antioxidant properties.

Some of the mushroom extracts inside the formula seem to genuinely support the immune system. The manufacturer cites this study, for example, showing that reishi, shiitake, and maitake mushroom extracts create an immunomodulatory response, helping your immune system function.

A separate study performed by researchers at the University of Florida showed that daily consumption of shiitake mushroom could improve the immune system. Another study backed up that research, showing that healthy young adults could boost their immune function by taking shiitake mushrooms every day.

These studies show clear benefits of mushroom extract. It’s no secret that certain mushrooms are linked with health benefits, and ongoing research continues to teach us new information about mushroom extracts every day.

However, it’s hard to definitively compare the ingredients in Mushroom Defense with the studies linked above. The shiitake mushroom study from the University of Florida, for example, used a daily dose of four ounces of shiitake mushrooms per day. It’s unclear how that dose compares to the 266mg of shiitake mushroom extract included in each serving of Mushroom Defense.
