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.
Vitamin C is an essential nutrient involved in the repair of tissue and the enzymatic production of certain neurotransmitters.
Zinc is essential for a healthy immune system and is enhanced by quercetin, which helps the zinc better penetrate your cell membranes for optimum effectiveness.
Vitamin D is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, and involved in many other biological effects.
Z-Stack is 100% kosher and GMP certified.
