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. Quercetin has been shown
to block the mechanisms by which microbes enter the host
cells and replicate within the body. Additionally, a human
clinical trial found quercetin supplementation supported
healthy respiratory function following a stressor (i.e., intense
bout of exercise), compared to placebo.
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. 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. 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
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. NAC is found
to raise glutathione levels, which is important to protect the
biologic activity and safe metabolism of quercetin. Along
with protecting the activity of quercetin, NAC supports all
detoxification pathways and helps maintain immune balance
by supporting glutathione levels.
Zinc is essential for maintaining immune system integrity and
healthy immune development. Supplementation with
zinc supports key immune functions such as natural killer cell
activity and phagocytosis by macrophages and neutrophils.
Furthermore, studies show that zinc can directly support the
body during immune system challenges and can help support
healthy respiratory function.
It has been shown that low vitamin D levels have immunologic
implications with a significant decrease in immune function,
affecting respiratory health. 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. Along with these immune-supporting benefits,
vitamin D has also been shown to support the respiratory
system and epithelial tight junction integrity.
