|What Is It?
N-Acetyl-l-Cysteine (NAC) is a derivative of the dietary
amino acid l-cysteine. NAC has a high affinity for
lung tissue, which it supports through mucolytic and
antioxidant action. NAC also enhances glutathione
production and plays a role in heavy metal detoxification.*
Uses For NAC
Immune And Respiratory System Health: When mucus
thickens, it can become difficult to expel. Due to its sulfur
content, NAC is able to disrupt disulfide bonds, thinning
the mucus so that it, along with the trapped particles and
bacteria, are more easily expelled from the lungs. NAC is
a powerful free radical scavenger and thus supports
epithelial cell health and healthy cilia activity in the
respiratory tract. NAC is also a precursor to the
antioxidant glutathione. Supplemental NAC increases
tissue levels of glutathione. Lymphocytes, specific
components of the immune system, rely on glutathione to
function properly. Tissues enhanced with glutathione
support overall antioxidant protection and help to
maintain a healthy immune response. A multicenter,
randomized, double blind trial with 262 participants
indicated that NAC supplementation for 6 months
supported upper respiratory tract and immune system
health. A recent meta-analysis of 8 double blind, placebo
controlled trials provided additionalsupport for NAC's ability
to support respiratory tract health.*
Supports Heavy Metal Detoxification: Several studies
suggest that NAC administration to animals may help to
reduce mercury and cadmium accumulation in the
kidneys and liver and/or to moderate the effects of these
metals in these tissues. NAC may achieve these actions in
part by facilitating mercury removal from tissues,
promoting healthy glutathione levels, or protecting
tissues from peroxidation generated by heavy metals.*
