What’s in the pack?

• Quercetin: Quercetin promotes a healthy immune response and provides excellent support for antioxidant processes, helping protect cells from harmful free radicals. Quercetin also supports cardiovascular health, helps maintain healthy blood pressure levels already in the normal range, and promotes healthy HDL function.* Vitamin C: Vitamin C supports healthy immune function by helping promote natural killer cell and white blood cell activities.*

• EGCG: This ingredient from decaffeinated green tea leaf extract is categorized as a flavonoid polyphenol, which can help promote antioxidant processes in the body.* N-acetylcysteine (NAC): A metabolite of the sulphurcontaining amino acid cysteine that stimulates the biosynthesis of glutathione, a key antioxidant produced in the body. Glutathione plays an important role in protecting the body against oxidative stress.*

• Vitamin D3: This is the most bioavailable form of supplemental vitamin D. Vitamin D provides unique support for long-term immune health and well-being. Some research suggests that vitamin D sufficiency may contribute to healthy cardiovascular function.*

• Zinc: A mineral that plays an essential role in maintaining healthy immune system function. In addition, zinc is a component of numerous enzymes in the body related to energy metabolism, bone mineralization, and protein synthesis.*
