Introducing MMIS (Multi-Mushroom Immune Support)

“My doctor says there’s nothing to do to boost my immune system except to eat a well-balanced diet.”

Good News! Medicinal Mushrooms have been used for thousands of year to improve immunity and are supported by hundreds of clinical trials.

Mushrooms offer an excellent culinary umami flavor to many of our favorite dishes, but they also offer so much more for health, especially immunity. Having a healthy immune system is at the top of everyone’s priority list these days. It’s no secret that what we choose for our diet directly impacts our ability to fight infection.

Culinary mushrooms include the white button mushrooms, cremini and portobello varieties, all available at your grocery store. In choosing mushrooms to optimize immunity, the difference is primarily the amount and the variety of polysaccharides and beta glucans. Those with clinically significant amounts are known as medicinal mushrooms.

Multi-mushroom immune support (MMIS) contains concentrates of mushrooms with clinically proven immune support benefits and a concentrate of beta 1,3/1,6 glucan. Taking two capsules of MMIS daily is an easy and convenient way to support your immune system.

Fitness Quest MMIS (Multi-Mushroom Immune Support)
60 Capsules per bottle
Each capsule provides:
Reishi:      200 mg
Shiitake: 100 mg
Chaga:     100 mg
1-3 / 1-6 Beta Glucan: 60 mg

This powerful formulation is designed to support immunity in four ways:

  1. Direct antimicrobial action
  2. Stimulation of immune cell populations, including macrophages, T-cells and NK (Natural Killer) cells
  3. Balancing inflammation
  4. Reducing anxiety
reishi mushroom
Reishi Mushroom fruiting body

Reishi is a medicinal mushroom that supports metabolism and immunity. Studies show that the polysaccharides of this mushroom promote the production of interleukin – 2 and can enhance the germ-killing capacity of T lymphocytes. Reishi glycans can also improve glucose control, thus improving metabolic balance. Also known as an adaptogen, Reishi has also been shown to help reduce chronic inflammation.

chaga mushroom
Chunks of Chaga fruiting body

Chaga mushrooms contain polysaccharides made up of xylulose, rhamnose, mannose, glucose, inositol, and galactose. It also has antioxidant compounds called phenolics. These compounds contribute to what is known as “early stage antiviral activity” by blocking the fusion of a virus to membranes of our cells. Phenolic compounds also protect lymphocyte DNA from oxidation, thus protecting the central information center of the immune system. Like other mushrooms, Chaga can improve blood glucose balance and promote liver health.*

Beta Glucans work activate immune cells known as macrophages, improving their surveillance and fighting abilities.

Beta-1,3/1,6 glucan is derived from yeast cell walls and significantly enhances immune system response. Macrophages in the gut take up beta glucan and transport active molecules to the lymph nodes, spleen and bone marrow. Beta Glucans signal macrophages to improve their immune response, and have been shown to enhance coordination between various immune populations.

shiitake mushroom
Shiitake Mushrooms

Shiitake is a popular medicinal mushroom that might be available at your grocery store. Slice and sauté them in butter or olive oil with diced garlic and onions to add a healthy immune support to your meal. Or just make sure to take your MMIS everyday!

Eating this mushroom every day for as little as four weeks has been found to improve immunity by doubling natural killer cell production and improving mucosal immunity. Better mucosal immunity means direct protection in the mouth, throat, gut and airways. *

Be a friend to you immune system and take MMIS!
