Z-Flu - Immune Support + Elderberry

Z-Flu Elderberry Gummies

Z-Stack® is one of Dr. Zelenko's premier products that he specifically designed.

With decades of experience in the medical field, the knowledge Dr. Zelenko has gained over the years led to him formulating his own supplement, which we now know as Z-Stack™.

Z-Flu has all the same ingredients you have come to love about Z-Stack plus Elderberry in a unique gummy delivery system.

Available to ship by late November

Z-Flu was developed with real, all-natural ingredients.

The ingredients in each gummy of Z-Flu weren't chosen at random – they were chosen specifically for their natural ability to help support the immune system and provide natural defenses when you need it most. With the added benefits of Elderberry this gummy specifically targets viruses and viral activity in the body.

Vitamin C (click to expand)

Supplementation of vitamin C has been found to improve components of the human immune system such as antimicrobial and natural killer cell activities.

Vitamin D3

Vitamin D supports a resilient immune system by fortifying your body defenses against bacteria and virsues.

Zinc

Zinc is a nutrient found throughout your body, that helps your immune system and metabolism function. Evidence suggests that if zinc supplementation is started within 24 hours of cold/flu symptoms starting, the supplement can help shorten the duration of illness.

Quercetin

Quercetin promotes a healthy inflammatory response, while supporting sinus and upper respiratory health. This nutrient helps your body better absorb and utilize vital nutrients like Vitamin C.

Elderberry

Packed with antioxidants, provides a boost to the immune system, has been shown to ease cold and flu symptoms while decreasing systemic inflammation

Say goodbye to flu season with Zelenko's Immune Boosting Gummy Formula.

Making sure your body takes in enough elemental zinc into the cells has always been at the forefront of Dr. Zelenko's philosophy to boosting immune defenses.

Z-Flu provides foundational immune supporting ingredients but also adds Elderberry. We took it one step further by bringing you a pure extract at its highest concentration, delivering four times more bioavailability than the elderberry used in competing formulas.
