Z Stack Vitamins Review: Things To Consider Before You Buy

Virus infections are proving dangerous day by day. Scientists are working hard to find a cure or prevention against various viruses. Many scientists have come up with new inventions or new medications to fight viruses. Some of them proved to be futile while other medicines proved to be handy against virus attacks.

Here in this article, we will discuss one particular medicine that has the capability to fight viruses. This is being called Z Stack Vitamins. This Multivitamin has been invented by Dr. Vladimir Zelenco. Let’s have a brief discussion about Z Stack Vitamin and Dr. Zelenko.

Who is Dr. Vladimir Zelenko?

Who is Dr Vladimir ZelenkoBefore knowing about Z-Stack we need to know about its inventor first. The name of the inventor of Z-Stack is Vladimir Zelenko. Vladimir Zelenco was born in Kyiv, Ukraine in 1973. He is mainly a family physician. He is renowned for promoting a three-drug mixture of hydroxychloroquine, azithromycin and zinc sulfate as part of the Zelenko Protocol, the investigational treatment for Virus attacks. He’s also accused of spreading false medical information, conspiracy and falsehoods concerning the treatment of viruses.

Zelenko claimed that he has given successful treatment to hundreds of Virus patients with his medicine course. The course length is 5 days. He claimed it in a public letter to US President Donald Trump on March 23, 2020. Despite the uncertainty of his treatment result, Zelenko’s treatment approach rapidly gained attention, with numerous media celebrities and Trump administration officials supporting it. Rudy Giuliani along with Mark Meadows, one of the Trump administration chief of staff has supported him.

This multivitamin has many essential nutrient elements such as Vitamin C, Vitamin D, Zinc and Quercetin. All these ingredients are proved to be effective against viruses and colds. But Z-Stack doesn’t have enough certifications that support it as a cure to viral attacks. Despite having no certifications, Z-Stack is gaining popularity day by day.

Z-Stack contains quercetin, zinc, vitamin C, and vitamin D3 according to the product details. We examined the proportions of each of the components in Z-Stack for potential safety and immunologic benefit since the particular constituent combination of Z-Stack is not investigated yet in a medical trial.

Below we will discuss the nutrient ingredients of Z-Stack. We will discuss their importance and effectiveness against virus attacks.

Vitamin C

By taking Z-Stack you will get 800 mg of vitamin C. Usually Sick persons take slightly higher doses (usually 1 gram daily) of vitamin C to mitigate the duration, risk and seriousness of colds in the cold season. Consuming vitamin C, on the other hand, is not that capable of preventing colds unless you are deficient. Some websites have advocated vitamin C pills can fight viral infections even better than colds. However, there is no clear evidence that shows more vitamin C than the appropriate daily dose intake (75 to 120 mg every day) has the ability to prevent virus infection, and medical researchers have not indicated that issuing a higher dosage of vitamin C to viral infected patients does have a significant impact.

When consumed in a balanced way, vitamin C is perfectly safe. But it might trigger burning of the heart, dysentery, and other problems. Adults, on the other hand, do have a tolerably high level of daily intake of 2,000 mg of vitamin C, which includes intake from fruits, drinks or beverages and foods

Taking Z-Stack might get dangerous for people who already get a lot of vitamin C from their food or drug supplements. An extra amount of Vitamin C could be too much for them. As it can escalate many side effects like kidney damage or kidney stones.

Vitamin D

Every single unit of Z-Stack has 125 mcg of vitamin D3. This is a bit alarming, as it exceeds the daily dose (600–800 IU) and the appropriate daily dose for vitamin D (that is 4,000 IU for a healthy adult). The danger of health hazards increases above this level, including the danger of hypercalcemia (excess level of calcium in the blood), which might cause troubling bowel movement, weakness, loss of appetite and kidney problems.

Vitamin D can effectively deter colds and breathing and other respiratory problems in people that don’t have enough vitamin D in their blood, as per research. But Vitamin D add-on pills are not that helpful in treating colds for persons who have appropriate vitamin D levels. Blood with low vitamin D levels relates to a higher possibility of viral infection, thus vitamin D add-ons have sparked interest as a way to minimize these risks. As per initial research, supplementation of Vitamin D prevents viruses, especially for the people with low levels of Vitamin D. But Z stack could increase the risk of getting caught by viruses, especially for the people who have high levels of Vitamin D.

Z-Stack contains 30 mg of zinc per serving (from 130 mg of zinc sulfate). Most people would not be benefited from having zinc unless they have a zinc deficiency. Zinc is relatively common in the elderly, vegetarians, and people who take certain drugs. Taking zinc (e.g., 20 mg per day, per pill of Z-Stack has the same amount of Zinc) might actually improve the immune system and can minimize the risk of respiratory difficulties in such individuals. Although zinc capsules have been shown to minimize cold symptoms, it appears that effectiveness needs an appropriate amount of zinc (as zinc gluconate or zinc acetate) taken as a capsule so that it would break down in the throat, where it is thought to play a role with direct effectivity — not as a pill/capsule, as in the scenario of zinc capsules.

Apart from mild stomach irritation as well as an unpleasant taste, zinc capsules have almost no bad impacts. The zinc amount in Z-Stack, on the other hand, is similar to the highest tolerable Daily Intake Level for zinc, which is 40 mg a day. Too much dose of zinc can react with copper absorption, leading the immunity to be weakened and other harmful impacts. As a result, if you take a 40 mg or higher dose of zinc daily, you also must take some supplement of copper (around 1 to 3 mg each day), that Z-Stack does not contain.

Each serving of Z-Stack includes 500 mg of quercetin. although scientists have proved that quercetin might help mitigate cold and respiratory infections. But there is uncertainty if it helps to fight cold or not. It is not clear also if the quercetin pills prevent or provide treatment for virus attacks or not. There is also uncertainty about the proper dosage.

Stomach upset, mild nausea, headache are the side effects of quercetin. Eating foods that are full of quercetin can help to minimize the GI side effects. Certain statins, estrogens, methotrexate, midazolam, thyroid hormone, ibuprofen, and other medicines, estrogens, methotrexate, thyroid hormone, certain statins, ibuprofen and others may be impacted by quercetin.
