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