What's in the bottle?
Quercetin is one of the most abundant antioxidants found in our diet and itself has strong anti-viral properties. The major benefit of taking quercetin with zinc is that the quercetin will push the zinc into the center of the cell where the zinc can stop the virus from reproducing.
Elderberry is packed with antioxidants, and may boost the immune system, ease cold and flu symptoms, and has been used to lessen stress.
Vitamin C supports protecting tissue from infection, may boost the immune system, and helps in the recovery of illness.
Zinc helps your immune system fight off invading bacteria and viruses. Your body also uses zinc to make DNA (the genetic material in cells) and proteins, and supports healthy new cells in the body.
Vitamin D is essential for bone health as well as muscle and nerve functions. Vitamin D also helps the immune system fight off bacteria and viruses.
Z-Flu is 100% kosher.
This bottle contains a 1-month supply.
