Viral Protocol from IFM

The IFM has a substantial list of supplements that have anti-viral properties. Here is the link:

I have reproduced some of the information here. Omitted are any suggestions that are not vetted with what I consider adequate research. I also added olive leaf extract at the bottom of the IFM list.

Background and Introduction

Health professionals and the public must be well informed about the SARS-CoV-2 virus, the disease it causes (COVID-19), and how it spreads. This information is readily available and not within the scope of this document. At this time, there are no specific vaccines or uniformly successful treatments for COVID-19. In this context of insufficient evidence, the scope of this document will be to assess the scientific plausibility of promising prevention approaches and therapeutic (nutraceutical and botanical) interventions and then to offer clinical recommendations. This article is part one of a series. Click here to view part two.

With respect to interventions, the practice of Functional Medicine emphasizes the primacy of safety, validity, and effectiveness. In the novel context of COVID-19, validity in the form of published evidence is lacking. Therefore, “validity” relies upon inferences from the mechanisms of action of individual agents and/or published outcomes data supporting their mitigating effects on illness from other viral strains. Likewise, data for the “effectiveness” of interventions targeting the viral mechanisms of COVID-19 are nascent and rapidly emerging. In this context, the following recommendations represent the Functional Medicine approach to the COVID-19 crisis:

  • Adherence to all health recommendations from official sources to decrease viral transmission.

  • Optimizing modifiable lifestyle factors in order to improve overall immune function (an introductory document on boosting immunity is available here). This should reduce progression from colonization to illness.

  • Personalized consideration of therapeutic agents that may:

  • Favorably modulate cellular defense and repair mechanisms.

  • Favorably modulate viral-induced pathological cellular processes.

  • Promote viral eradication or inactivation.

  • Mitigate collateral damage from other therapeutic agents.

  • Promote resolution of collateral damage and restoration of function.

  • Treatment of confirmed COVID-19 illness (as per conventional standards and practice):

  • May reduce the severity and duration of acute symptoms and complications.

  • May support recovery and reduce long-term morbidity and sequelae

Various mushrooms species have been shown to possess broad immunomodulatory effects. They possess multiple mechanisms of action, including increasing the number of circulating B cells,5 increasing gut immunity,20 stimulating host immunity,21 activating innate immune cells,22 and increasing cytotoxic activity of NK cells.23
