Support a healthy immune response*
Protect against oxidative stress*
Support cardiovascular health*
Quercetin is a polyphenolic flavonoid substance that has excellent free radical scavenging antioxidant activity, and each pack provides 750 mg. Quercetin not only promotes a healthy immune response, but it supports cardiovascular health by maintaining healthy blood pressure levels already in the normal range, promoting healthy HDL function, and supporting endothelial health.*
High-potency vitamin C
Each serving features 1,200 mg of vitamin C, with 1,000 mg as Ultra Potent-C (for reference, one orange typically has around 62 mg). Vitamin C is a key antioxidant and plays a role in supporting immune health. Ultra Potent-C, a unique buffered form of vitamin C, supports immune function by helping promote natural killer cell and white blood cell activities.*
High-potency vitamin D3
Vitamin D insufficiency is common and is increasingly considered an emerging global health issue. Vitamin D plays a role in health by providing support for long-term immune function, and some research also suggests that vitamin D sufficiency may contribute to cardiovascular health.*
Epigallocatechin gallate (EGCG)
EGCG is the most abundant polyphenol in green tea, and the 150 mg of EGCG in Immune Defense Pack is derived from decaffeinated green tea extract. Polyphenols can help promote antioxidant processes in the body.*
NAC is a metabolite of the amino acid cysteine. It acts as a precursor to the synthesis of glutathione. Glutathione is produced in the body and plays an important role in protecting against oxidative stress and supporting healthy liver detoxification processes.*
This essential mineral plays a role in maintaining a healthy immune system. In addition, zinc is a component of numerous enzymes in the body related to energy metabolism, bone mineralization, and protein synthesis.*
