Underground Labs NAC (N-Acetyl-Cysteine) is the supplement form of the semi-essential amino acid cysteine. Cysteine is necessary for replenishing the most powerful antioxidant in your body, glutathione - responsible for fighting free radicals and maintaining a healthy immune system as well as fighting cellular damage.
The supplement form of NAC plays a huge role in your body's detoxification process and is a great tool to use for a healthy liver. This close-to-magic amino acid has also been shown to help to regulate the most important neurotransmitter in the brain - glutamate. For healthy brain function, glutamate and glutathione must remain in balance.
Adequate levels of glutathione levels in the lungs have been shown in studies to help decrease inflammation in the bronchial tubes and lung tissue. It has also, in the past been used to improve symptoms of chronic obstructive pulmonary disease (COPD.) In a one year study, 600mg of NAC a day significantly improved lung function in those with COPD.
Many studies have proven NAC to be possibly among the most important supplements for overall health and a powerful defensive immune system.
