In the aftermath of COVID-19, many people struggle with the debilitating fatigue and brain fog known as Long COVID. This condition is not just lingering; it’s a disabling disruption of daily life. The newest research suggests that the persistence of symptoms may be due to a combination of factors: tissue damage linked to ACE 2 receptors, ongoing viral activity, imbalances in gut health, impaired energy production at a cellular level, and relentless inflammation.
Recognizing the complexity of Long COVID, researchers have developed a comprehensive targeted diet, lifestyle, and supplement strategy designed to target the root causes. It is aimed squarely at these five key drivers. This protocol is meticulously crafted by researchers and clinicians at the forefront of the long covid battle. For people dealing with the overwhelming fatigue and brain fog of long covid, this research-based 90-day protocol offers hope for reclaiming your a sense of control over your health.
Post-Viral Fatigue Was Known Long Before Covid Came Along
Throughout history, there have been numerous instances of widespread post-viral fatigue, often referred to as “post-viral syndrome” or “post-infectious fatigue syndrome”. These episodes typically arise following significant viral epidemics. They present as a complex of symptoms including profound fatigue, cognitive difficulties, and various physical symptoms that persist beyond the acute illness.
One of the earliest recognized episodes of post-viral fatigue syndrome followed the 1918 Spanish flu. That influenza pandemic infected a third of the global population and was estimated to have killed 50 million people worldwide. Survivors of the devastating outbreak reported persistent fatigue, neurologic issues, and functional impairments that persisted long after the acute illness had passed. The condition was often referred to as “encephalitis lethargica” or “sleepy sickness”, and while the exact causative connection was never established, the coincidence that it happened right after the Spanish flu pandemic was difficult to ignore.
Perhaps the most well-known example of post-viral fatigue is Chronic Fatigue Syndrome (CFS), which surged in recognition during the 1980s and has been linked to various viral infections. Infections with the Epstein-Barr virus and Ross River virus, among others, have all been associated with the later development of CFS/ME. People with this condition experience severe, unexplained fatigue, cognitive difficulties, sleep abnormalities, and a range of other symptoms. Then, there was the outbreak of a similar illness in Lake Tahoe, Nevada, in the late 1980s. Over 200 people fell ill with what appeared to be an initially acute illness that eventually gave way to a chronic condition characterized by profound fatigue.
Prevalence of Long Covid
So the appearance of “long covid’ is really only just the most recent example of post-viral fatigue. Another fancy term is “Post-Acute Sequelae of SARS-CoV-2 infection” (PASC). Symptoms commonly reported include severe fatigue, cognitive difficulties often referred to as “brain fog”, shortness of breath, and others.
Estimates of long COVID prevalence in the general U.S. population range from 10% to 30% of all cases of acute infection, with higher rates among older, female, hospitalized, and unvaccinated patients.

The 5 Main Drivers of Post-Viral Fatigue

Study Hypothesis
Researchers have hypothesized that there are 5 main drivers:
- Tissue damage: widespread cell damage in the heart, lungs, and brain are thought to be drivers of long covid.
- Viral persistence: whole viruses or viral fragments are possible.
- Chronic Inflammation is documented in long covid.
- Gut microbiome disturbance is documented in long covid.
- Blood vessel micro-clotting related to tissue damage may be causing impaired oxygenation.
How Supplements Target The Drivers of Long Covid
The protocol supplements were carefully chosen by the researchers for this long covid protocol study. Although the list is extensive and costly, each supplement targets a critical aspect of the complex physiology driving long covid. There is a highly detailed explanation in the second workshop video showing how each of these supplements works.
- Foundational Supplements were selected to support the healing of widespread tissue damage.
- Tolovid was chosen to target viral clearance. [PMC7286838], [Case Study, ResearchGate]
- ITIS was chosen to address chronic inflammation.
- MegaSporeBiotic and prebiotic address gut microbiome disturbance.
- Arterosil was chosen to address vascular damage. [PMID: 36332287]
Overview of the Long-Covid Treatment Protocol
- Plant-Based Anti-Inflammatory Foods: Inflammation is the hallmark of long covid, so the diet during this period of recovery must be as anti-inflammatory as possible. The Whole30 diet is discussed below.
- Targeted Supplements: These address tissue damage, inflammation, vascular damage, viral clearance, and gut dysbiosis.
- Sleep: Quality sleep is critical to the success of your recovery. Our sleep article will provide some strategies that have been proven to work.
- Stress Management: Stress Management is critical to the recovery of your energy. There are many resources for meditation that can help you learn techniques for calming down, but sometimes a person gets stuck in a state of “fight or flight” where extreme anxiety is triggered by the tiniest of stressors. There are two programs that are specifically designed to “reset the limbic system” to help a person to get out of the “fight or flight” state of being. These 2 well-regarded programs are the DNRS Program and the Gupta Program. Recently, the Gupta program published a study validating that the process of “Amygdala and Insula Retraining (AIR)” significantly reduces fatigue compared to a placebo wellness program. [PMC10365910]
- Physical Activity: The main guideline for physical activity is to listen to your own body. Do as much physical activity as you feel you can do without setting yourself back. Post-exertional malaise is a real thing, and it’s counterproductive.
Additionally, you may need Breathing Exercises to help support your physical activity efforts. Here’s a basic guide for Bouncing Back From COVID-19. And, if your symptoms since covid include rapid heart rate upon standing, dizziness, or fainting, you may be experiencing “Postural Orthostatic Tachycardia Syndrome” (POTS). If so, this POTS Exercise Program may be helpful.
Ovation Research Study
Although we are now more than 3 years into the pandemic with untold thousands of people in the US and worldwide suffering from long covid symptoms, there are still no formal studies to prove what works best in recovery. That sad and frustrating fact is the motivation for the current ongoing study and the current research protocol.
The origin of this post-viral protocol is described in the two videos that follow. These workshop videos were designed to educate medical providers on how to implement the protocol and how to participate in the ongoing study. The study is designed to prove scientifically how well this protocol of targeted nutritional supplements plus an anti-inflammatory diet with lifestyle measures works to alleviate long covid symptoms.
Documenting Your Progress
Even if you are not participating in the formal research study described in the videos, you will want to follow the study protocol closely for your best chance at recovery. And when you invest so much in following the protocol, you will want to be able to tell whether it is really working.
It can be hard to remember how you were feeling 2 or 3 months ago, so it’s easy to miss how much progress you are actually making. This leads to wondering whether the protocol is really working or if it might be “all in your head” or the placebo effect. Here’s where the Promise-29 Questionnaire comes in. Along with the symptoms table below, it can help you get your symptoms down on paper in a documented way.
- Promise-29 Questionnaire: This questionnaire should be taken repeatedly: once before treatment to establish a baseline of symptoms, and then at days 30, 60, and 90 of the treatment program to document changes in various symptoms over the course of time.
- Timeline and Progression of Symptoms Table – this might be helpful in communicating with your physician about the complex timelines of your many symptoms.

This first session lays out the theories that experts have about what is driving Long Covid symptoms. It also discusses the logistical issues related to the research study.
Post-Viral Recovery Workshop -Session 2
This second session takes a deep dive into the supplements that are prescribed in the protocol.
Update: October 2023
It was discovered that there is a problem with absorption of tryptophan from the gut, therefore a new recommendation for 100mg of 5-HTP to be added to the protocol to increase serotonin synthesis for mood support.
What To Eat For Long Covid Recovery
There are many diets that are anti-inflammatory to one degree or another, but research has shown that a plant-based diet is effective in reducing symptoms that are common to people experiencing long covid. [PMC8429479]
The Whole 30 Diet meets these criteria and was chosen for the research protocol because it has so many practical resources on the Whole30.com website:
- Whole 30 Diet Program Rules
- Plant-Based Recipes
- Plant-Based Whole30 Details
- Grocery Guide
- Shopping List
The Whole30 diet is usually used as a month-long nutritional program, but long covid sufferers should follow it during the 90 days of the protocol to get the benefits of its anti-inflammatory effects. The primary principle of the Whole30 program is to remove certain food groups from your diet that are often linked to inflammation, digestive issues, and cravings, including sugar, artificial sweeteners, alcohol, grains, legumes, dairy, and processed foods.
Supplement Plan 90-Day Overview
Shown on the left, there are core supplements that are meant to help your basic body needs. On the right, is a schedule for the specialty supplements for Long Covid.
Core Supplements

Preparing For The First Month
As much as we would all love to point to a cheap and easy fix for Long Covid, this protocol definitely involves some work. Between ordering the supplements and planning for food and exercise changes, it will take some time to get started with the protocol. Again, here are the links to some practical resources:
- Whole 30 Diet Program Rules, Work On Sleep, Get Physical Activity, and Manage Stress.
- Print out 4 Copies of the Promise-29 Questionnaire. Mark your calendar to record your symptoms on Day 1, Day 30, Day 60, and Day 90 to document your progress.
The Second Month
Again, remember to record the Promise-29 Questionnaire on Day 30 and Day 60 to document your progress. Keep following the Whole 30 Diet to get those critical anti-inflammatory benefits. Keep working on Sleep. Keep working to Manage Stress. Do what you can to stay active while avoiding post-exercise fatigue. Together, all these things are critical and work synergistically with the supplementation protocol to support your recovery.
The Third Month of The Protocol
By now, you may be feeling better and encountering temptations to eat french fries and ice cream. But remember: all those foods you have been avoiding are the ones that drive that drop-dead fatigue-inducing inflammation you are trying so hard to leave behind. You deserve a full recovery and the wrong foods threaten to sabotage that energy you need so badly. So, keep following the Whole30 plan for at least the whole 90 so that you can get those critical anti-inflammatory benefits.
Don’t forget to record the Promise-29 Questionnaire on Day 60 and Day 90 to document your progress. Keep working on Sleep and Manage Stress. Do what you can to stay active while avoiding post-exercise fatigue. Together, all these things are critical and work synergistically with the supplementation protocol to support your recovery.
To Sum It Up
It’s clear that Long COVID’s chronic symptoms require a multi-pronged approach. The 90-day protocol we’ve shared here, grounded in solid research, offers a practical roadmap for those struggling with the fatigue and confusion that Long COVID brings. By combining specific dietary changes, lifestyle habits, and supplements, there’s real potential for sufferers to alleviate their symptoms and regain a sense of normalcy. As this field evolves, so will our strategies, always aiming to improve the lives of those affected by Long COVID. This protocol isn’t just about managing symptoms—it’s a step towards taking back control of your health and your life.

After recovering from COVID-19, many people continue to face lasting fatigue and brain fog—often referred to as Long COVID. These symptoms can deeply affect daily routines and make even simple tasks feel difficult. Recent studies point to several possible reasons for why these symptoms continue: tissue damage related to ACE2 receptors, lingering viral activity, shifts in gut health, problems with how cells produce energy, and ongoing inflammation.
To address this, researchers and clinicians have put together a detailed approach using diet, lifestyle changes, and targeted supplements. This plan focuses on the five main areas thought to drive symptoms. Designed with care by experts working closely with Long COVID cases, the 90-day protocol aims to help people begin restoring their energy and mental clarity through a structured, research-based plan.
Post-Viral Fatigue Was Known Long Before Covid Came Along
Throughout history, there have been many reports of ongoing fatigue and other lasting symptoms after viral infections. These cases are often called post-viral syndrome or post-infectious fatigue. They usually appear after large outbreaks and involve a mix of long-term fatigue, trouble thinking clearly, and other physical symptoms that continue after the initial illness has ended.
One of the first major examples followed the 1918 Spanish flu. That pandemic infected about a third of the world’s population and caused widespread illness and loss of life. Many survivors went on to report lingering tiredness, neurological symptoms, and difficulty functioning. At the time, some of these cases were described as “encephalitis lethargica” or “sleepy sickness.” Although no direct link to the virus was confirmed, the timing made a connection likely.
A more familiar example is Chronic Fatigue Syndrome (CFS), which gained attention in the 1980s and has been tied to several viral infections. Viruses like Epstein-Barr and Ross River have been linked to the later development of CFS. People affected report deep fatigue, memory and concentration issues, sleep disruption, and other symptoms that don’t resolve quickly. A cluster of similar cases also appeared in Lake Tahoe in the late 1980s, where more than 200 people became sick with what began as a typical illness but later developed into a long-lasting condition marked by exhaustion and cognitive issues.
Prevalence of Long Covid
The rise of what’s now called “long COVID” is simply the latest example of post-viral fatigue. It’s also known by a more technical name—Post-Acute Sequelae of SARS-CoV-2 infection (PASC). Common symptoms include deep fatigue, trouble with memory or focus often called “brain fog,” shortness of breath, and other lingering effects that continue well after the initial illness has passed.
Estimates suggest that about 10% to 30% of people who get COVID-19 may continue to have symptoms afterward. Rates appear to be higher among those who are older, female, unvaccinated, or who were hospitalized during the initial illness.

The 5 Main Drivers of Post-Viral Fatigue

Study Hypothesis
Researchers believe there are five main factors that may be driving long COVID:
- Tissue damage: Ongoing effects from cell damage in organs like the heart, lungs, and brain may play a role.
- Viral persistence: Some studies suggest that pieces of the virus, or even whole viruses, may remain in the body.
- Chronic inflammation: Inflammation lasting well beyond the initial infection has been observed in many cases.
- Gut microbiome disturbance: Imbalances in gut bacteria have been found in people with long COVID.
- Micro-clotting in blood vessels: Small clots may form, limiting oxygen delivery to tissues and possibly contributing to ongoing symptoms.
How Supplements Target The Drivers of Long Covid
The protocol supplements were carefully chosen by the researchers for this long covid protocol study. Although the list is extensive and costly, each supplement targets a critical aspect of the complex physiology driving long covid. There is a highly detailed explanation in the second workshop video showing how each of these supplements works.
- Foundational Supplements were selected to support the healing of widespread tissue damage.
- Tolovid was chosen to target viral clearance. [PMC7286838], [Case Study, ResearchGate]
- ITIS was chosen to address chronic inflammation.
- MegaSporeBiotic and prebiotic address gut microbiome disturbance.
- Arterosil was chosen to address vascular damage. [PMID: 36332287]

If so, this POTS Exercise Program may be helpful.
Ovation Research Study
More than three years into the pandemic, many people in the U.S. and around the world are still dealing with long COVID symptoms. Yet there are still no clear studies showing which treatments work best for recovery. This gap in knowledge is what led to the development of the ongoing study and the current research protocol.
The background and goals of this post-viral approach are explained in the two videos below. These workshops were created to guide medical professionals on how to use the protocol and how to take part in the study. The goal is to gather solid evidence on how a plan that includes specific nutritional supplements, an anti-inflammatory diet, and lifestyle changes might help reduce long COVID symptoms.
Documenting Your Progress
Even if you’re not part of the formal research study described in the videos, it’s still a good idea to follow the same protocol carefully to give yourself the best shot at feeling better. And when you’re putting in the time and effort, it’s important to have a clear way to track whether things are improving.
It’s often hard to remember exactly how you felt a few months ago, which can make it difficult to see real progress. This uncertainty can lead to doubt about whether the protocol is actually helping. That’s where the PROMIS-29 Questionnaire comes in. Along with the symptom timeline table below, it gives you a way to track your symptoms clearly and consistently.
- Promise-29 Questionnaire: This tool should be filled out multiple times—once before starting, then again at 30, 60, and 90 days into the plan. It helps document changes in your symptoms over time.
- Timeline and Progression of Symptoms Table – This can be a helpful way to organize and explain the pattern of your symptoms, especially when discussing them with your healthcare provider.

- Whole 30 Diet Program Rules
- Plant-Based Recipes
- Plant-Based Whole30 Details
- Grocery Guide
- Shopping List
The Whole30 diet is often followed for just a month, but for people dealing with long COVID, it’s recommended to continue the plan for the full 90 days of the protocol to support the body’s recovery. The main idea behind Whole30 is to take out certain foods that are commonly linked to inflammation, digestive discomfort, or cravings. These include sugar, artificial sweeteners, alcohol, grains, legumes, dairy, and processed foods.
Supplement Plan 90-Day Overview
On the left side, you’ll see a list of core supplements that support your general health needs. On the right is a schedule for the supplements that focus more specifically on managing symptoms related to Long COVID.
Core Supplements
