Product Description

N-Acetyl-L-Cysteine 1000mg


What Is It?

N-acetyl-l-cysteine is an Antioxidant Vitamin and (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 has one of the best antioxidant action. NAC also enhances glutathione production and plays a role in heavy metal detoxification.

Uses For NAC

As an Immune Vitamin for 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 is more easily expelled from the lungs, along with trapped particles and bacteria. NAC is a 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, and supplemental NAC increases tissue levels of glutathione. As fundamental components of the immune system, lymphocytes rely on glutathione to function properly. Tissues enhanced with glutathione support overall antioxidant protection and help to maintain a healthy immune system. A multicenter, randomized, double-blind trial with 262 participants indicated that NAC supplementation for six months supported upper respiratory tract and immune system health. A recent meta-analysis of eight double-blind, placebo controlled trials provided additional support for NAC’s ability to support respiratory tract health. Supports Heavy Metal Detox: Several animal studies suggest that NAC administration may help with heavy metal detox to reduce mercury and cadmium accumulation in the kidneys and liver and/or to moderate the effects of the metals in those 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.

What Is The Source?
