Z Stack | Immune System Support by Dr. Zelenko

Vladamir Zalenko MD is a board-certified physician in New York. He has provided counsel to White House personnel, governments on four different continents, hospitals, physicians, celebrities and nursing homes.

After careful examination, Dr. Zelenko put together an all-natural formula design for supporting the natural defense system of the body.

Early Treatment | Antiviral Ingredients

Based on my front-line experience, it is essential to start treatment against Covid-19 immediately upon clinical diagnosis of the infection and not to wait for confirmatory testing. There is a very narrow window of opportunity to eliminate the virus before pulmonary complications begin. Delaying treatment is the essence of the problem. My treatment regime is attached and please know that as of today it has saved thousands of patients without serious complications or negative side effects. Hundreds of top doctors across the world have embraced prehospital treatment of Covid-19 in high-risk patients. – Dr. Vladamir Zelenko

Zinc Immune Support

Zinc is one of the active ingredients in Z Stack. It is one of the most well-known immune support ingredients to date.

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.

Quercetin Plant-Based Nutrients

Quercetin is a leading active ingredient in Z Stack. Being a plant flavonol, quercetin is a natural source of vital nutrients.

Quercetin was discovered by the Nobel Prize winner Albert Szent-Gyorgyi. Quercetin, a zinc ionophore, is known for its antioxidant activity, antiviral activity, and more.

Quercetin has a number of great health-promoting benefits. Peer reviewed literature shows potential benefits of Quercetin include the ability to help reduce inflammation and to improve the immune system.

The scientific community has published a significant amount of research on quercetin, including clinical trials.

Vitamin C

Vitamin C, a well-known immune-enhancing ingredient improves the effects of Zinc and Quercetin for an overall powerful formula.

Vitamin C, or ascorbic acid, is a water-soluble vitamin well known for its role in supporting a healthy immune system. Vitamin C contributes to immune defense by supporting various cellular functions of both the innate and adaptive immune system. Because our bodies cannot make vitamin C, it must come from the foods you eat every day.

Vitamin D

Vitamin D is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium,  phosphate, and many other biological effects.

Vitamin D is essential to a healthy immune system as it initiates the adaptive immune response. It promotes the expression of a protein called cathelicidin which can promote the stimulation of T cells to help support an immune response. The link between vitamin D and viral infections was observed during winter months when vitamin D levels are generally lower.

Z Stack Instructions:

Take 2 capsules per day to boost your immune system. It’s important to take these with food, Zinc might make some people nauseous – especially if you are not used to it. If you feel something coming on, take another 1-2 capsules to help you suppress viral replication. Think about adding CBD Tinctures or CBD Capsules to this regimen for even more improved immunity.
