Benefits of ImmuneStart

ImmuneStart is one of the most potent immune supplements available. It contains the legendary herb astragulus and 6 of the world’s most treasured mushrooms. ImmuneStart combines these scientifically researched nutrients to provide extraordinary immune support.

The benefits of the ImmuneStart include

  • Broad spectrum immune support
  • Cold and flu prevention and support
  • Support for chemotherapy and radiation treatments

The mushrooms in ImmuneStart are pharmaceutical quality, concentrated extracts of their mycelium, extracellular compounds, fruiting bodies and spores. It takes over 250 pounds of mushrooms to create 1 pound of ImmuneStart mushroom extract. Each recommended dose contains over 560mg of soluble beta-glucans and polysaccharides. Beta-glucans and polysaccharides found in medicinal mushrooms stimulate the production of immune cells to guard our bodies’ cells against foreign invaders, protecting us from aberrant and abnormal cell growth.

The certified organic mushrooms and ingredients in ImmuneStart include

  • Agaricus blazei
  • Cordyceps Sinensis
  • Maitake
  • Shiitake
  • Coriolus versicolor
  • Reishi
  • Astragalus

Astragalus has been treasured for centuries for its health and longevity enhancing properties. It is one of the safest herbs for long-term usage. It is often recommended by Chinese herbalists as the most important energy and immunity tonic for our busy and demanding Western lifestyles.

  • Astragalus has potent immuno-modulating, anti-allergenic, anti-microbial, anti-viral and adaptogenic properties.
  • Chinese medicine uses astragalus to reduce the adverse effects of the radiation and chemotherapy, strengthen the immune system, and to prevent and treat common colds and upper respiratory infections.
  • Astragalus benefits digestion, boosts metabolism, normalizes blood pressure and supports the cardiovascular system.

ImmuneStart’s mushroom extract has been shown in clinical trials to have a particularly powerful synergistic, immune-enhancing effect when taken concurrently with chemotherapy and radiation.

ImmuneStart is a safe and natural immune supplement that can be used by anyone who desires a healthy immune system and lifestyle. 100% vegetarian, 100% pure with no fillers or other additives.

ImmuneStart and Immune Assist™ Frequently Asked Questions

Can ImmuneStart be used by everyone?

Yes. ImmuneStart is safe and natural. It can be used as a daily supplement by anyone wanting to maintain healthy immune system functions and a healthier lifestyle.

What ingredients are in ImmuneStart?

ImmuneStart uses the trademarked product Immune Assist™, a proprietary blend made from the immune active hetero-polysaccharides concentrated and purified from 6 popular all-natural, 100% USDA Certified Organic mushroom species (Cordyceps sinensis, Agaricus blazei, Lentinula edodes, Grifola frondosa, Ganoderma lucidum, and Coriolus [Trametes] versicolor). ImmuneStart also includes the immune enhancing herb astragalus (4:1 extract).

Is Immune Assist™ made in America?

Yes. Immune Assist™ is made in America, using only 100% USDA Certified Organic materials. This is the only product of its kind that is made in America. Most other medicinal mushroom derived immune supplements are imported from China. Mushrooms are so effective at pulling toxins out of soil that they are being used to clean up sites contaminated with heavy metals and radiation. As a result, when buying medicinal mushrooms we need to be sure that they were grown in pristine conditions. Organic sources ensure that this is so.

Is ImmuneStart made from hot water extracts?

There are some companies selling their products on the internet which would have you believe there is a special process called “hot water extraction”. This is a great marketing claim, but really, the term “hot water extract” is the same as saying ‘mushroom tea’. Immune Assist™ is made by a far more complex proprietary process. The purification process used with Immune Assist™ goes through a number of steps to separate, concentrate and purify the bioactive hetero-polysaccharide compounds, which are then dried, analyzed for purity and encapsulated. It takes over 250 pounds of 6 different types of fresh medicinal mushrooms to make 1 pound of finished Immune Assist™. The finished Immune Assist™ product contains more than 200 different types of clinically-proven polysaccharide immune modulators.

What about arabinoxylane, the compound that is found in MGN3? Does ImmuneStart contain this polysaccharide?

Yes. ImmuneStart contains not only arabinoxylane, but also lentinan, grifolan (Dr. Nanba’s original Maitake D-Fraction), PSK and PSP, and active hemicellulose correlated compound (AHCC).

Why does ImmuneStart include astragalus?

The roots of the herb astragalus have a long history of use in herbal medicine to maintain a healthy immune system (Winston D, Kuhn MA. 2008. Winston and Kuhn’s Herbal Therapy and Supplements: A Scientific and Traditional Approach, 2nd edition. PA: Lippincott Williams and Wilkins). Even before it was adopted by Western herbology, astragalus had been used for centuries by Traditional Chinese Medicine to “tonify the spleen and augment the qi (vital energy)”. Spleen deficiency, in Chinese Medicine, shows up in symptoms that include lack of appetite, fatigue, spontaneous sweating and diarrhea. It is also traditionally used in TCM to tonify the lungs and to treat those with frequent colds. The only time that one should not use astragalus is when a fever is present.
