NAC

Great to have this especially if you need to get better from a flu or bad cold. I try to have a bottle on hand all the time. It smells like rotten eggs but it works.

More Info

What Is N Acetyl Cysteine?

Aging is a natural part of life that can go smoothly with the help of NAC ...

N-acetyl cysteine (NAC) is a derivative of the amino acid L-cysteine and is a more stable form of this amino acid for supplementation. NAC is a precursor to the important antioxidant, glutathione. glutathione works in the liver to change chemicals and metabolic byproducts into harmless substances for excretion from the body. NAC is also an antioxidant in its own right. It detoxifies heavy metals like mercury, cadmium, and lead.

N Acetyl Cysteine Benefits

It protects all cells of the body from damage due to aging, helps immune cells kill invading microbes (especially viruses) and stops cells from being harmed by radiation and chemotherapy. NAC is recommended by natural health practitioners for conditions such as frequent colds and flu, asthma, bronchitis, acetaminophen toxicity, heavy metal toxicity, low immunity and decreased liver functioning. Supplementation of NAC has been shown to improve the body’s glutathione levels.

NAC is available as an encapsulated powder. Large NAC doses may cause diarrhea. NAC may inactivate some antibiotics and insulin.

How To Take NAC

Adults can take 1 capsule 1-2 times per day. Take with a protein-containing meal. Or follow labelling directions or the direction of your health care practitioner.
