Dr. Zelenko’s Z-Stack

Dr. Zelenko, the doctor that created the Z-Stack, explains how and why this product came to be. (Created in Dec 2021)

Dr. Zelenko has been proven right! But don’t take our word for it, just go to the National Institute of Health’s website and look at the study THEY published: Therapies to Prevent Progression of COVID-19, Including Hydroxychloroquine, Azithromycin, Zinc, and Vitamin D3 With or Without Intravenous Vitamin C: An International, Multicenter, Randomized Trial.

This peer-reviewed study, which even uses the term “Zelenko Protocol,” found that 236 of 237 patients with ages ranging from 22 to 99, treated at 7 different hospitals, FULLY RECOVERED!!!


Vitamin D is an important nutrient for your body. It aids the absorption of Vitamin C for strong healthy bones. Vitamin D also can support your immune system, muscle function, and brain cell activity.

Vitamin D isn’t naturally found in many foods, but your body also makes Vitamin D when exposed to sunlight. Vitamin D deficiency is a particularly serious issue for people with darker skin.

In the recent NIH-published study that vindicated the Zelenko Protocol, researchers noted that 97% of the 237 patients had a vitamin D deficiency. In fact, more than half of those treated were what is considered severely vitamin D deficient (55% of participants at <25 nmol/L). Take your vitamin D – it is a key part of Z-Stack Vitamins.


Quercetin is a plant-based product that contains antioxidants. According to a medically reviewed document on Healthline.com, quercetin is one of the most abundant antioxidants in our diets and plays an important role in helping your body combat free radical damage, which is linked to chronic diseases. While the science on all the benefits of quercetin is not settled, according to Healthline.com it may reduce

  • inflammation
  • allergy symptoms
  • blood pressure

You can get quercetin from a variety of different foods. Examples of foods with quercetin include onions, pomegranates, chamomile, black grapes, blackberries, oregano, capers, and kale.


Zinc is found in cells throughout the body. It helps the immune system fight off invading bacteria and viruses. Zinc is essential for our immune system because it affects how our cells respond to infections. It can also help keep inflammation under control.

Zinc increases the activation of cells in the body that are responsible for fighting infection. It also activates enzymes that break down proteins in viruses and bacteria to reduce the chances of spreading.

Due to its direct antiviral properties, it can be assumed that safe zinc administration is likely beneficial for most of the population, especially those with suboptimal zinc status.


The following is guidance from the U.S. Department of Health and Human Services:

Know your rights. Every day they are under attack by authoritarians who seek to control more than is needed across a range of different issues, including health and public safety. As a patient, you have certain rights. Some are guaranteed by federal law, such as the right to get a copy of your medical records, and the right to keep them private. Many states have additional laws protecting patients, and healthcare facilities often have a patient bill of rights.

An important patient right is informed consent. This means that if you need a treatment, your health care provider must give you the information you need to make a decision.

Many hospitals have patient advocates who can help you if you have problems. Many states have an ombudsman office for problems with long-term care. Your state’s department of health may also be able to help.


Consider the likely percentages and ways in which the risks might affect you. For example, how effective are the ingredients in Z-Stack vitamins in protecting you and your family from upper respiratory illnesses? Studies show a measurable percentage reduction in the chances of contracting certain illnesses. How does that fit into your family’s regimen? You may not be a race car driver deciding if you can pass a competitor, but you are doing something infinitely harder and more important: caring for yourself and your family.

In all areas of your, and your family members’ lives, you should be thinking about risk reduction. Law enforcement officers do it when making a traffic stop, race car drivers do it entering a turn at high speeds and moms do it every day, from deciding whether it is safe for a child of a certain age to ride a bike to school, to making sure their family has a healthy diet.
