The Calm & Sleep Bundle

Vitamin C has been shown to play a complex, protective role against toxic compounds formed from oxidized lipids and may support overall immune health.

Quercetin supports a healthy inflammatory response and functions as a zinc ionophore, helping shuttle zinc into cells so your body can better absorb and utilize it.

Vitamin D3 has been shown to increase intestinal calcium and phosphate absorption, helping maintain strong bones.

Zinc is a nutrient found throughout your body that may support your immune system and metabolic function.

Z-Stack® is an all-in-one immune support formula designed to provide key nutrients your body relies on for daily immune defense. Each serving combines vitamin C, vitamin D3, zinc, and quercetin, ingredients selected to work together to support immune function, antioxidant protection, and healthy cellular activity.

Unlike many standard vitamin blends, Z-Stack® was developed from the research and clinical insights of Dr. Vladimir “Zev” Zelenko. Each component was carefully selected to work synergistically, helping support immune function and overall wellness in a single, convenient daily formula.

The ingredients in Z-Stack® are designed to work synergistically. Quercetin acts as a zinc ionophore, helping transport zinc into cells, while vitamins C and D3 support immune response and antioxidant protection—helping your body maintain strong natural defenses.

Z-Stack® is typically taken once daily as a two-capsule serving, making it a convenient way to support immune health with multiple nutrients in one formula rather than taking separate supplements.
