N-acetyl-L-cysteine - far more than just a cough suppressant

N-acetyl-L-cysteine - NAC for short - is the acetylated form of the amino acid cysteine and is characterized by its higher bioavailability and stability. Probably the most common application of N-acetyl-L-cysteine is its function as a very effective cough suppressant and mucolytic. NAC is used in clinical facilities for the treatment of respiratory diseases such as colds, chronic bronchitis or COPD (3,4). However, the active ingredient also has a whole range of other health benefits.

Positive effects of N-acetyl-L-cysteine

The health benefits of N-acetyl-L-cysteine begin with its pronounced antioxidant properties. These are based, among other things, on the fact that NAC can strongly stimulate the production of glutathione - the body's most powerful antioxidant (1). Antioxidants protect the body's genetic material and cells from damage and destruction by free radicals. Free radicals are highly reactive molecules that have been linked to a variety of dangerous diseases such as cancer, heart disease, Alzheimer's, diabetes and many others (5). Furthermore, scientific studies have shown that oxidative stress can even accelerate the ageing process (6). Another benefit of N-acetyl-L-cysteine is that it significantly improved training performance and regeneration after training in the subjects of one study (7). Athletes who train hard can particularly benefit from these antioxidant effects, as large quantities of free radicals are inevitably produced during intensive physical exertion as part of the energy metabolism, which can also damage muscle cells (5). In addition, N-acetyl-L-cysteine can stimulate nitric oxide production, which can result in vasodilation and increased blood flow (8). This can improve the supply of oxygen and nutrients to the muscles during and after training and thus have positive effects on training performance and regeneration. Numerous studies have also shown that N-acetyl-L-cysteine was able to improve and restore the function of the immune system in test subjects (9), which is partly due to the stimulation of glutathione production. N-acetyl-L-cysteine can also have a positive effect on heart health. Due to its antioxidant properties, it is able to protect heart tissue from oxidative damage - a known trigger for heart disease - and thus reduce the risk of heart disease (1,10). On top of this, it also increases nitric oxide production and can therefore improve blood flow to the heart (8, 11). According to researchers, N-acetyl-L-cysteine plays an important role in the body's detoxification processes and has been shown in studies to protect the test subjects' bodies from the harmful effects of drugs and environmental toxins (12). As a result, NAC can protect both the liver and the kidneys and is therefore also used in cases of poisoning and for the treatment of liver diseases (13).

N-acetyl-L-cysteine is an active ingredient that is not only used to treat coughs and bronchial congestion, but also has a whole range of other clinical applications. As always, GN supplies the active ingredient in an optimally absorbable form and guarantees the best quality. This is the only way to ensure that all effects unfold optimally and that you can fully benefit from N-acetyl-L-cysteine. N-Acetyl-L-Cysteine from GN Laboratories - because in the end only results count.
