GN NAcetyl LCysteine ​​120 Capsules

N-Acetyl-L-cysteine ​​(NAC) is a synthetic form of the amino acid cysteine, which does not occur naturally in the human body or in food but is artificially produced. It is sold both as a drug and as a dietary supplement.
Effects of NAC as an expectorant in respiratory diseases:
NAC has been known as an expectorant since the 1960s and is used for various respiratory diseases associated with thick mucus production, such as acute and chronic bronchitis, COPD (chronic obstructive pulmonary disease), and cystic fibrosis.
The expectorant effect of NAC is based on its ability to break down disulfide bonds between the proteins in the mucus. This makes the thick mucus thinner and easier to cough up. In addition to its expectorant properties, NAC also has antioxidant and anti-inflammatory effects, which can have protective effects in respiratory diseases.
Usual Dosage for Adults:
For adults, NAC is usually recommended as an expectorant at a dosage of 600 to 1200 mg per day. This daily dose can be divided into 1 to 3 individual doses, for example, 600 mg once a day or 200 mg three times a day. For acute and chronic bronchitis, 300 to 600 mg of NAC can be taken per day, and for the common cold, 200 to 400 mg.
It is important to note that the expectorant effect of acetylcysteine ​​is enhanced by adequate fluid intake. NAC should not be taken with cough suppressants, as these can impede mucus expectoration. When taken concurrently with certain antibiotics (such as penicillin, tetracycline, cephalosporins, or aminoglycosides), an interval of at least 2 hours should be observed, as NAC can weaken their effect.
About the product GN N-Acetyl L-Cysteine ​​120 Capsules:
The product GN N-Acetyl L-Cysteine ​​120 Capsules contains 500 mg of N-acetyl-L-cysteine ​​per capsule. The recommended intake is 1 to 2 capsules daily. This corresponds to a daily dose of 500 mg to 1000 mg of N-acetyl-L-cysteine. The capsules should ideally be taken with plenty of water between meals.

N-acetyl-L-cysteine ​​(NAC) plays a crucial role as a precursor for the body's own synthesis of glutathione. Glutathione is a tripeptide composed of the three amino acids glutamic acid, glycine, and cysteine. In this process, cysteine ​​is the limiting factor, as it is often available in lower quantities inside cells compared to the other two amino acids. NAC is a stable form of cysteine ​​that, after ingestion, efficiently enters cells and is deacetylated to L-cysteine. By providing this building block, NAC enables the body to maintain or increase glutathione production when needed.
The liver's detoxification function is primarily supported via two pathways:
1. Phase II detoxification (conjugation): The liver uses glutathione to bind toxic substances, metabolic byproducts, heavy metals, and drug residues. This binding makes the toxins water-soluble, enabling their excretion via the kidneys or bile. Without sufficient glutathione, these pollutants could not be efficiently neutralized.
2. Protection against oxidative stress: During breakdown processes in the liver, free radicals and reactive oxygen species (ROS) are continuously produced. Glutathione acts as the body's most important endogenous antioxidant, neutralizing these aggressive molecules. In doing so, it protects liver cells (hepatocytes) from oxidative damage and supports the integrity and regenerative capacity of liver tissue.
Supplementation with GN N-acetyl L-cysteine ​​thus ensures that the liver has sufficient glutathione reserves to effectively perform its functions as a central detoxification organ while simultaneously protecting itself from cell damage.

Supplementation with N-acetyl-L-cysteine ​​(NAC) has a significant impact on mental health because, as a precursor of L-cysteine, it promotes the synthesis of glutathione, the body's most important endogenous antioxidant, and directly influences glutamate metabolism. In the brain, NAC modulates the glutamatergic system by regulating extracellular glutamate levels via the cystine-glutamate antiporter. Mental health conditions such as depression or obsessive-compulsive disorder (OCD) are often associated with an imbalance of this neurotransmitter, with hyperexcitability due to excessive synaptic glutamate playing a central role. By increasing the extracellular cystine concentration, NAC stimulates the exchange process, leading to increased glutamate release from the cell into the extracellular space. There, it activates presynaptic receptors, which in turn inhibit further glutamate release into the synaptic cleft. This mechanism contributes to the stabilization of neuronal signal transmission and can reduce the repetitive thought patterns typical of obsessive-compulsive disorder (OCD) as well as the neurotoxic stresses that occur in depression. Furthermore, NAC has anti-inflammatory properties and protects nerve cells from oxidative stress, which improves neuroplasticity and strengthens overall psychological resilience. With regard to the product GN N-Acetyl-L-Cysteine, the intake of this amino acid offers targeted support to normalize these physiological regulatory circuits, with clinical observations showing that, particularly with long-term use, significant symptom relief and an improvement in general mood can be achieved.

Taking N-acetyl-L-cysteine ​​(NAC) protects cells from oxidative stress by serving as a precursor for the formation of glutathione, one of the body's most important antioxidants. Glutathione neutralizes free radicals, thus preventing cell damage, which can help slow the aging process and reduce the risk of chronic and degenerative diseases. Furthermore, NAC acts directly as an antioxidant and stabilizes cell membranes, thereby supporting overall vitality and cell regeneration.
