Immune Health is one of the most comprehensive formulas available on the market today

How does it work?

Immune Support is a targeted blend of nutrients designed to provide a broad-spectrum support to the body’s immune reserves. The formula includes quercetin, a powerful bioflavonoid that aids in supporting the immune system. Vitamin C and N-acetyl cysteine are potent antioxidants that promote respiratory function and support the function of quercetin. Vitamin D and zinc are important micronutrients needed to create a robust immune reserve. This powerful combination works to promote healthy respiratory and immune function.

Your immune system is a complex infrastructure that protects your body from all foreign invaders that threaten your health. But the fact is modern society has taken a toll on human immunity. It’s believed that human immunity is getting weaker due to a variety of factors, including lack of proper nutrition, environmental factors, increased stress, inactive lifestyle, autoimmune issues, and more.

The unique blend of powerful antioxidants, essential vitamins, and minerals works synergistically to enhance immune function, promote respiratory health, and provide protection against oxidative stress. Additionally, this supplement may contribute to improved cardiovascular health, reduced inflammation, and better brain function, while also offering potential benefits for blood sugar regulation and cancer prevention. Incorporating this supplement into your wellness regimen can help you maintain a strong immune system and support your body’s natural defenses, ensuring optimal health and well-being.

Quercetin is best known for its antioxidant activity in scavenging free radicals. Additionally, quercetin helps balance the level of cytokines and improve T-lymphocyte balance. Several mechanism studies highlight quercetin’s ability to provide immune system support while also stimulating the ciliary beat frequency of the nasal epithelium, aiding the excretion of respiratory mucus.1,2,3 Quercetin has been shown to block the mechanisms by which microbes enter the host cells and replicate within the body.3 Additionally, a human clinical trial found quercetin supplementation supported healthy respiratory function following a stressor (i.e., intense bout of exercise), compared to placebo.4.

Vitamin C

Vitamin C is a potent antioxidant that has been studied for many years for its immune-supporting effects. Through its antioxidant functions, vitamin C has been shown to protect important immune cells from oxidative damage.5 Data shows vitamin C is heavily concentrated in macrophages, supports lymphocyte activity, modulates cytokine release, improves endothelial function, restores mitochondrial function, and can directly support a challenged immune system.3 Of particular interest, vitamin C has been shown to recycle oxidized quercetin back to its parent compound, which supports a robust immune response while increasing the efficacy of quercetin.3,6

N-Acetyl Cysteine

N-acetyl cysteine (NAC) is the precursor of the master antioxidant, glutathione. NAC has been shown to support mucus clearance and normal respiratory function, through its ability to cleave disulfide bonds in mucus.7,8 NAC is found to raise glutathione levels, which is important to protect the biologic activity and safe metabolism of quercetin.3,9 Along with protecting the activity of quercetin, NAC supports all detoxification pathways and helps maintain immune balance by supporting glutathione levels.10,11


Zinc is essential for maintaining immune system integrity and healthy immune development.12,13,14 Supplementation with zinc supports key immune functions such as natural killer cell activity and phagocytosis by macrophages and neutrophils.15 Furthermore, studies show that zinc can directly support the body during immune system challenges and can help support healthy respiratory function.15,16

Vitamin D3

It has been shown that low vitamin D levels have immunologic implications with a significant decrease in immune function, affecting respiratory health.11,12,17 This is most likely because the vitamin D receptor is expressed by several immune cells including monocytes, macrophages, dendritic cells, B and T cells.18 Supplementation with vitamin D has been shown to modulate NK cell activity to promote a healthy innate immune response.15,19. Along with these immune-supporting benefits, vitamin D has also been shown to support the respiratory system and epithelial tight junction integrity.15,19,20,21
