Scientific strategies to improve your immunity and fight COVID-19: Part Two

Updated: Mar 5

Confused about how to keep yourself and your loved ones safe from COVID-19? Exhausted trying to keep up with the latest news and information? You’re not alone.

If you think about the current pandemic in terms of a race, COVID-19 had a really, really big head start.

Doctors, scientists, and drug companies are running as hard as they can to catch up, but when it comes to a footrace, they’re more tortoise than hare. That’s a good thing. We want them to be careful and measured.

But humans are in this race, too, and we need all the help we can get. That’s why we at GlobalCures have compiled a list of relatively non-toxic nutrients and medications — some over the counter — that have scientific and/or clinical evidence suggestive of efficacy against the virus.

How We Formulated These Recommendations

COVID-19 is caused by a novel, or new, virus (SARS-Cov-2). Because the virus is new, there is no current effective treatment for patients outside the hospital and a vaccine is still months away from release.

Faced with this reality, many frontline physicians are making a valiant effort to repurpose FDA approved drugs and readily available supplements to battle the disease.

One such clinician is Dr. Paul Marik, M.D., Chief of Pulmonary and Critical Care Medicine, Eastern Virginia Medical School in Norfolk, Virginia. Marik and his colleagues have searched the literature and compiled a list of supplements and drugs that may be useful for the treatment of COVID-19. (Clinicians can read Marik’s comprehensive document here.)

We’ve reviewed Dr. Marik’s work and that of other physicians who have published their experiences addressing COVID-19 and synthesized the information to form the recommendations we make below.

While the data supporting our suggestions is not ironclad, the components in these protocols are generally regarded as safe. They are also inexpensive and readily available.

Of course, generally doesn’t mean always, and you should check with your doctor before adopting any of these protocols. Please note, these dosing suggestions apply to adults and not children.

We will update this document as science evolves and as we learn more. Check back often to see whether and how our recommendations have changed.

General Guidelines For Everyone During the COVID-19 Pandemic

  • Wash your hands frequently.

  • Avoid touching your face.

  • Maintain a social distance of 6 feet or more from others.

  • Wear a mask any time you cannot stay 6 feet or more from others who are not in your household (indoors or outdoors).

  • Avoid crowded places such as bars or restaurants.

How To Protect Yourself After COVID Exposure Or While Caregiving For a Positive Patient

In this post, we lay out the supplements we recommend for general immune boosting and as a defense against COVID-19.

If you have been exposed and/or are caregiving for a COVID-19 patient, you will want to continue that protocol. We recommend you boost the zinc dosage (see below) for one week and add two medications that are widely used for acid reflux and allergies. Both have been used in COVID-19 patients with some success.

Also consider adding the supplement quercetin. Quercetin is an anti-oxidant, anti-viral and immune enhancer found in many fruits and vegetables. It works even better when combined with Vitamin C.

Long term quercetin use may be associated with hypothyroidism (13). As such, we recommend using quercetin for one week only unless your physician is able to monitor your thyroid status. If you have hypothyroidism, do not add the quercetin without consulting your physician first.

Links to references are provided for clinicians and anyone else wanting to dig deeper.

  • Zinc 50 mg/day (This is an increase from the general protocol.) Increase for one week.

  • Famotidine 20-40 mg/day ( 1, 2, 3, 4)

  • Cetirizine 10 mg/day (5)

  • Quercetin 250 mg twice daily (13). Do not use more than one week

What To Do If You Test Positive and Experience Mild Symptoms of COVID-19

We hope that you can avoid getting an infection by taking the recommended precautions and following our protocol. If you do test positive and have a mild case, we recommend monitoring your oxygen saturation with a home pulse oximeter.

Additionally, continue to take all the supplements mentioned above and in this post, and consider adding the following drug at the dosage recommended below.

If you are not able to enroll in any of the current trials, ask your doctor if he/she would prescribe these drugs for off-label use.

  • Doxycycline 100 mg twice a day for 5 days (9, 10, 11)

Please seek immediate medical attention if your symptoms become severe.
