Medical Mushrooms + Key Immune Nutrients

This is a great All-in-1 formula for Phase 1 and Phase 2 on the COVID timeline.  

ImmuCore® contains the COVID foundation nutrients such as vitamin C, D3 and zinc plus an anti-viral medicinal mushroom combination that helps to prime the immune system for viral invasion.  

Crudely, your immune system has security guards and police. Security guards detect invaders first and call the police. Medicinal mushrooms boost numbers of security guards mostly, then the police. 


Medicinal mushrooms are indicated to be used in the Prevention and Infection Phases only of The 4 Phases of COVID.

  1. Prevention Phase: Support is focused on immune surveillance efficiency and reduction of baseline levels of inflammation, to improve outcomes if the patient becomes infected.

  2. Infection Phase: Support emphasizes immune activity against infection.


      3. Escalating Inflammation Phase: Don't take medicinal mushrooms. 

      4. Recovery PhaseDon't take medicinal mushrooms.

    • Zinc’s main role is to help your body increase white blood cells and fight off infection. It also assists with the release of antibodies.
    • Deficiency has been linked to increased instances of sickness so zinc is commonly used for the prevention and treatment of colds and flu.
    • Look for supplements that combine the power of vitamin C and zinc.

    • Suggested dose - COVID or viral prevention: 30-60mg
    • Pregnant women should aim for 12 mg per day since it’s essential for normal fetal development.
    How to incorporate
    • If you’re eating a healthy well-rounded diet, you should be getting in the proper amount of zinc per day without needing a supplement.
    • During winter and flu season, supplementstion might be needed to maintain slightly higher levels for a few months. 
    • If getting over a cold quickly is your goal, supplementing at least 75 mg per day can reduce cold duration and symptoms so you can get back to your life.
    • Zinc may decrease absorption of some antibiotics when taken at same time
    • Zinc may increase side effects of cisplatin
    • Zinc may decrease the absorption of penicillamine
    • Amiloride may increase amount of zinc in body

    Zinc plays a crucial role in the function of essentially all immune cells. Deficiency of this critical element has a profound impact on immune response, increasing susceptibility to a variety of infections.208-212

    One of zinc’s critical roles in immune function is its role in thymulin production and activity.213

    In addition, zinc has specific and well-known antiviral properties.214

    Increasing intracellular zinc concentrations in cell culture impairs the replication of a variety of RNA viruses including SARS-CoV-1. Intracellular zinc has been shown to inhibit RNA synthesis by suppressing the SARS-CoV-1 replication and transcription complex.215

    In vivo evidence for zinc’s antiviral role comes from a Cochrane review that found zinc intake was associated with a significant reduction in the duration of the common cold. Many of the studies showing benefit when taken during the course of an infection were in the form of a zinc lozenge.216 It makes sense to utilize this mode of delivery during the acute infection phase.

    Zinc has also been shown to suppress Th17 cell development.217

    Interleukin-17 (IL-17) made by Th17 cells has been shown to drive an inflammatory feedback loop via IL-6 induction.218

    Zinc dependent transcription factors are involved in the regulation of the gene expression of IL-6 and TNFα.219

    The effect of SNPs in genes encoding zinc transporters on blood zinc levels in humans has been examined.220

    Older individuals with gain of function IL-6 SNPs have been shown to have a greater need for zinc.221

    Zinc supplement in older individuals with gain of function IL-6 SNPs and low zinc were shown to have lower IL-6 and MCP-1 levels upon zinc supplementation.222

    Anosmia (loss of smell) and dysgeusia (distorted sense of taste) are commonly being reported in patients at every phase of COVID-19.223

    These are also classic symptoms of zinc deficiency. It is too early in the discovery process to determine if this is cause or effect, nonetheless zinc deficiency greatly impairs immune function, especially resistance to viral infections. Notably, inadequate dietary consumption of zinc is found in almost half the older population.224
