Product Details

Seeking Health N-Acetyl-L-Cysteine (NAC)

N-Acetyl-L-Cysteine (NAC) plays a very important role in preventing cellular detoxification and free radical damage. NAC is normally found in both the liver and the lungs, and enhances the body's ability to produce glutathione, one of the most critical antioxidants in the body.

NAC supports the health of your lungs, liver, and immune system. 

N-Acetyl-L-Cysteine Benefits

Promotes Brain Health and Nerve Cells

NAC's antioxidant properties help protect against damage to neurons, the specialized cells found in our nervous system that are vital to maintaining memory and cognitive function. 

Antioxidant Activity

NAC is needed to produce intracellular glutahione, needed for healthy function of the liver, nerve cells, brain, pancreas, and lungs. 

Immune and Respiratory Support

NAC has the ability to disrupt disulfide bonds of proteins found in mucus, allowing it to be more easily expelled from the lungs. The antioxidant action of NAC may also help protect the lungs and support the immune system. 

Supplementing with Glutathione on its own is not always the most effective way of providing cellular glutathione support. Oral supplements of N-Acetyl-L-Cysteine (NAC) is a reliable method of increasing glutathione levels inside cells. NAC is a derivative of the amino acid cysteine, used to to synthesize glutathione, one of the most important antioxidants compounds used by the body in Phase I and Phase II cellular detoxification. 

Suggested Use

Take one to two capsules daily for general detoxification and antioxidant support. To assist with lung infections or lung conditions, take 1to 6 capsules three times daily.
