Gear up with Immune Defense Pack. With ingredients like antioxidants, polyphenols, and high-potency vitamin C, D, and zinc, this arsenal of products is primed to support a healthy immune response as well as cardiovascular function.
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 sulphur-containing 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
