Z-Stack vitamin is a multivitamin advertised as an all-in-one immune-boosting super formulation. There is only a preliminary signal that definite ingredients in Z-Stack may have immune-boosting effects, although not essentially at the doses in Z-Stack. The amount of at least one of the ingredients in Z-Stack surpasses the Tolerable Upper Daily Intake Level, i.e., raises the peril of adverse effects.

The Z-Stack supplement includes vitamin C, vitamin D3, zinc, and quercetin, according to the product label. Since the precise ingredient amalgamation in Z-Stack does not seem to have been verified in a clinical trial, we have studied the amounts of each of its elements for potential security and immune Advantage. You can also check similar immunity boosting capsules, the Z-Dtox formula.

Ingredients of Z-Stack Formula

Z-Stack vitamin has the most effective and strong ingredients. Let us look into the elements.

Vitamin C

Z-Stack vitamin for sale includes 800 mg of vitamin C (ascorbic acid) per daily serving. There is proof that vitamin C may diminish the duration and severity of colds during the cold season when taken in somewhat higher doses before getting sick. Though, taking vitamin C does not seem to avert colds unless you are deficient. Some websites have endorsed vitamin C supplements to fight viral infections other than colds, like COVID-19. However, no proof getting more than the daily obligation of vitamin C (75 to 120 mg daily) can avert infection from coronavirus. Clinical research has not established a clear benefit of giving high-dose vitamin C to COVID patients.

At large, vitamin C is secure when utilized in moderate amounts, though it may cause diarrhea, heartburn, and other GI disturbances. However, the Tolerable Upper Daily Intake Level for vitamin C in adults is two thousand mg — and this comprises ingestion from foods, beverages, and supplements. For individuals already obtaining a significant amount of vitamin C from their diet or other accessories, taking Z-Stack may cause them to surpass this level, which may upsurge the peril of side effects, including kidney stones and kidney damage.

Vitamin D

Z stack protocol includes 125 mcg of vitamin D3 per serving. It is regarded as it is not only a method above the adult daily need (600 to 800 IU) but also overhead the Tolerable Upper Daily Consumption Level for vitamin D (which is 4,000 IU for grownups).

Research suggests that vitamin D may decrease the possibility of having cold and upper respiratory infections in people without having suitable blood levels. Vitamin D supplements are not helpful for colds in individuals who previously have vitamin D adequately. Since minor blood levels of vitamin D have been associated with a superior risk of infection and more Spartan symptoms and problems of COVID-19, there has been attention to vitamin D supplements to decrease these risks. Preliminary research recommended that supplementing with moderate- to high-dose vitamin D when vitamin D levels are low may boost the prognosis in public hospitalized with COVID-19. Still, there appears to be an augmented risk of COVID-19 in individuals with very high vitamin D levels, as could be instigated by the amount of vitamin D in Z-Stack.


Z-Stack offers 500 mg of quercetin per portion. Although there is an indication that quercetin may assist lessen upper respiratory tract infections after a workout, it is uncertain if quercetin helps diminish the peril of colds. It's also unsure if taking quercetin supplements can aid prevent or treat COVID-19 or what dosage would be active.


Z-Stack offers 30 mg of zinc (from 130 mg of zinc sulfate). Taking zinc is not probable to provide an immune advantage for most individuals unless they are deficient in zinc, which is more frequent in older adults, vegetarians, and those taking definite medications. In such people, complementing with zinc (e.g., 20 mg daily, which is similar to the dose in Z-Stack) may aid boost immunity and eliminate the peril of respiratory tract infections. Zinc lozenges diminish cold symptoms, and effectiveness appears to need a sufficient amount of zinc (as zinc gluconate or zinc acetate) taken as a tablet, so it can soften in the throat, where it is assumed to act directly — not as a capsule, as in Z-Stack.

Side Effects

Not many side effects are noticeable in this supplement but, the side effects of quercetin are unusual but may embrace mild nausea, stomach upset, and headache. The GI side effects can usually be abridged by taking quercetin with food. Be conscious that quercetin may affect the acceptance or metabolism of several medications.


Z-Stack costs range between $55 for 60 capsules. In our product reviews, one can obtain the exact amounts of these elements for as little as twenty-five cents (5 cents for 5,000 IU of vitamin D, 6 cents for 800 mg of vitamin C as ascorbic acid, three cents for 40 mg of zinc, and eleven cents for 500 mg of quercetin). So, you would be paying $1.60 extra per quota for these ingredients in Z-Stack, which would wind up costing you about forty-eight dollars more per month.
