Science-based Nutrition & Supplement Protocol for Covid-19


The purpose of this article is to provide some guidance on good nutrition and possible supplements to use during the current Covid-19 pandemic. These guidelines are based on many hours of reading and researching scientific articles and studies. Having said this, please note the following two important points:

  1. I am not a medical professional. If you choose to follow this science-based guidance, which I believe is solid, please understand that it is highly unlikely to be supported by conventional medicine, so follow at your own risk.
  2. This protocol should be considered secondary to the current CDC guidelines of proper hygiene and social distancing.
  3. Credit for this protocol goes to Chris Masterjohn.

Context: We Don’t Know Much About Covid-19

The current coronavirus pandemic is very new, and as such, we simply don’t have substantial, confirmed proof showing which foods and supplements prevent the risk of infection, or which will help lower the risk of death. However, it is possible to look at reliable scientific studies with regards to similar diseases and extrapolate a protocol from there that may be useful. However, please understand that this is not 100% guaranteed.

What We Know About Covid-19

The coronavirus gets into our cells by “hijacking” a substance known as ACE2. The role of ACE2 is to keep blood pressure from going too high and to keep our lungs and heart healthy. We also know that Vitamins A and D are incredibly important to our immune systems, as they make antibodies and help to regulate blood pressure by producing more ACE2. However, if we increase the amount of ACE2 that the coronavirus can “hijack”, then we are potentially opening up the door for more Covid-19 in our cells. As such, higher than normal amounts of Vitamin A and D right now is likely not a good idea.

In addition, vitamin A and C combined with an herbal remedy known as Umcka, create an immune-boosting cellular weapon known as interferon. Under normal circumstances, this would be really beneficial. Unfortunately, when it comes to interferon, the coronavirus most likely behaves similar to SARS ( t’s biology appears to be about 87% similar) which you may recall hit hard in 2003. SARS stands for “severe acute respiratory syndrome.” This virus poisons our ability to make interferon, in order for it to rapidly reproduce and create extremely large levels in our lungs. The levels are so large that it causes a massive inflammatory response that quite often leads to lung damage, and possibly death. At this time, it’s probably not a good idea to substantially increase interferon levels, beyond normal, as the virus may well use this to it’s advantage and to your detriment.

Finally, the science community widely agrees that coronaviruses belong to a much larger group of viruses known as “lipid-enveloped viruses”. This means that the virus has an oily coating that helps protect it from the human immune systems. The good news, however, is that this lipid coating is vulnerable to soap and other substances in foods and supplements that penetrate or dissolve the oily coating.

Keep washing your hands with soap and water. Be religious about it!

What We Have Learned From Other Similar Viruses

  • Elderberry extract/syrup is highly effective against human coronavirus NL63, which is also known to enter cells through ACE2, just like the current COVID-19. It directly halts the attachment of the virus to ACE2, so most likely does the same for the current coronavirus.
  • Zinc directly targets SARS’ ability to reproduce, so it is likely effective against the new coronavirus as well. Zinc inhibits the virus from replicating and once it has entered a cell. So, if the virus happens to get into our cells, but they are unable to replicate, then the infection should theoretically be minimal.
  • Copper: it has been reported that coronaviruses can survive for 5 – 9 days on most surfaces, including teflon, PVC, ceramic, glass, plastic, silicon, rubber, and stainless steel. Yet, they die within 5 – 30 minutes on surfaces that contain high concentrations of copper, like brass. Most researchers are in agreement that copper is toxic to the coronavirus. However, we need to be careful with copper because it must be properly balanced with zinc to be effective.
  • Garlic: garlic has never been tested against any of the coronaviruses, however, the main chemical component in garlic, allicin, combats at least six different viruses, including herpes and the common cold, as well as most cases of bronchitis and pneumonia. It does so by destroying the lipid envelope, so it is entirely possible that it may also destroy the lipid envelope of COVID-19.
  • Vitamin C is essential to life and is found in fresh plant foods. It is essential for a healthy immune system and is known to help one get better from a cold about one day earlier.


  1. Based on the scientific evidence, I think that the single most important thing would be to prevent the coronavirus from getting into our cells. Prevention is king! As such, taking elderberry extract for its highly likely potential to squash the viruses ability to attach to ACE2 is the #1 priority. How much? Human studies using elderberry to combat the common cold and flu typically use between 700-900 mg of elderberry extract per day, divided in two to four doses, either as lozenges, capsules, or syrup.
  2. The #2 priority would be zinc, due to its likely ability to inhibit replication of the virus, should you be exposed. Zinc can be obtained from foods, tablets, and lozenges. Lozenges are best for releasing zinc in the mouth, allowing it to travel into our nose and throat. Since medical professionals are now saying that exposure is most likely spread by way of the eyes, nose and throat, I highly encourage the use of zinc lozenges. In addition, I also think having a baseline of food-based zinc is also a really smart idea and this is where oysters absolutely shine. How much? 40 – 60 mg from food, plus another ~20 mg from a lozenge.
      • The best way to maximize the amount of zinc we get into our lungs is to eat one or two oysters three or four times per day, and to suck on one zinc lozenge daily. In order to get the zinc into your nose and throat, it is crucial that you let the lozenges dissolve slowly under your tongue, rather than chewing or swallowing them.
      • One final note on zinc, NEVER take zinc with whole grains, nuts, seeds, or beans, as these foods will block your ability to absorb the zinc.
  3. Copper: copper has to be balanced with zinc. For every 10-15 mg of zinc, we should get at least one mg of copper. Since the protocol recommendation calls for 60-80 milligrams of zinc from food, supplements, and a lozenge, this would be optimally balanced with approximately 6 – 8 mg of copper.
      • Some supplements add copper to their formula. Read the labels. Food is an excellent way to get copper – see below for 2 mg recommendations:
        8 Oysters
        25 grams of spirulina
        40 grams of shiitake mushrooms
        50 grams of sesame seeds
        50 grams of cocoa powder
        56 grams of 90% dark chocolate
        70 grams of 70% dark chocolate
  4. Garlic consumption daily: the most effective dosage against colds is 180 micrograms per day. This can be achieved by crushing one clove of raw garlic, or adding water to 4 grams of garlic powder, and letting it sit for ten minutes before eating it.
  5. Take 150 mg of Vitamin C daily, preferably from foods, such as green chilli peppers, bell peppers, currants, kale, broccoli, kiwifruit, jalapeno peppers, red chilli peppers, oranges, strawberries, pineapple, papayas, lemons, peas, cabbage, cauliflower, Brussels sprouts, banana pepper, red or cayenne pepper, mustard greens, persimmons, and/or kohlrabi.


The current Coronavirus pandemic is very serious. Please make the CDC guidelines your #1 priority, but I also highly encourage you to consider your nutrition as part of a healthy protocol. As mentioned above, this virus is new, so data is scarce, but the aforementioned protocol is science-backed. It is based on the research and studies of many brilliant scientists and medical researchers, and in my opinion is currently the best set of nutrition guidelines at our disposal.

Be safe. Be well.
