Nasetyylikysteiiniä

N-asetyylikysteiini, often abbreviated as NAC, is a derivative of the amino acid cysteine. It is a compound that plays a significant role in the body's production of glutathione, a powerful antioxidant. Glutathione is crucial for detoxification processes and protecting cells from oxidative stress.

NAC is available as a dietary supplement and is also used medically. In medicine, it is recognized for its mucolytic properties, meaning it can help break down and thin mucus in the airways. This makes it useful in treating respiratory conditions such as bronchitis, cystic fibrosis, and chronic obstructive pulmonary disease (COPD). NAC is often administered in inhaled form for respiratory issues or orally for other indications.

Beyond its use in respiratory conditions, NAC has been investigated for a range of other potential health benefits. Research has explored its effects on mental health conditions, including obsessive-compulsive disorder and addiction, though more studies are needed to confirm these applications. It has also been studied for its potential role in liver protection and in counteracting the effects of acetaminophen overdose. The body's ability to produce NAC is influenced by dietary intake of cysteine, but supplementation can increase its availability.
