Jarrow Formulas N-A-C is a dietary supplement which contains 500 mg of N-acetyl-L-cysteine (NAC) in a single capsule. NAC provides the body system with a sulphur amino acid – cysteine, which is essential for the synthesis of glutathione – a strong antioxidant.
N-acetylcysteine (NAC) is often used in the anti-neoplastic therapy, HIV treatment, in paracetamol and heavy metal poisonings, inflammations and as a support in wound healing processes. The compound can also be used as a perfect antioxidant agent, showing neuroprotective benefits. It is used to support the treatment of schizophrenia, Alzheimer's disease, depression and addictions.
As it affects the glutamate and dopamine neurotransmissions in the brain, NAC can be used in psychiatric medicine. Some researchers classify NAC as a nootropic agent because it is believed to have a positive impact on proper cognitive skills.
Glutathione – what it is and what kind of functions it has?
Glutathione is one of the most important antioxidant factors in the human body system. In the liver, it acts as one of the main detoxicants. It is also involved in a variety of other functions, such as transport of amino acids and production of coenzymes. It is believed that glutathione promotes the positive nitrogen balance by facilitating the synthesis of proteins. It increases cells hydration, muscle glycogen resources and the level of growth hormone. It reduces cortisol and lactic acid levels, accelerates the reduction of fat tissue, supports immunity and relieves symptoms of fatigue.
Deficiency of glutathione in the bloodstream may indicate a medical condition and that the body cannot deal with radical scavenging, which damages the cells. Moreover, the glutathione levels decrease with age. To raise its resources in the body system, you have to provide all necessary components which are needed for the glutathione synthesis. One of them is cysteine, which can be supplied in the form of N-acetylcysteine (NAC).
Numerous studies have confirmed that the use of acetylcysteine for the prevention of acute renal failure brings good results and can improve the results of hospital treatment. An additional advantage of such support therapy is a low probability of side effects and lower costs.
N-acetylcysteine is successfully used in the treatment of many psychiatric disorders. The scientific research provides great evidence for the effectiveness of the NAC in the treatment of autism, Alzheimer's disease, bipolar affective disorder, depression, schizophrenia, obsessive-compulsive disorder, addiction to drugs (cocaine, marijuana) and some forms of epilepsy.
There is a hypothesis that acetylcysteine has beneficial influence on the nervous system by modulating glutathione and dopamine neurotransmission and because of its antioxidant properties.
NAC has bactericidal properties and shows an ability to break down bacterial biofilms of important pathogens, including Pseudomonas aeruginosa, Staphylococcus aureus, Enterococcus faecalis, Enterobacter cloacae, Staphylococcus epidermidis and Klebsiella pneumoniae.
N-acetylcysteine may show indirect psychoactive action in two different ways. On the one hand, cysteine is transformed to cystine and thus it increases the release of glutamic acid in the extracellular space.
Glutamate activates the metabotropic glutamatergic receptors in group II (mGluR 2, mGluR 3), and at higher doses of NAC – mGluR 5 receptor also in group II. Glutamic acid can act as excitatory neurotransmitter in the nervous system. It is the basis of the process of the memory footprint formation and, thanks to that, it enables you to learn and remember.
On the other hand, it is responsible for increasing the amount of glutathione, which is probably also a neuromodulator. It can activate the NMDA and AMPA receptor in different ways. Recently, it has been discovered that it can have its own receptors in the nervous system.
To sum it all up, Jarrow Formulas N-A-C is a product designed for athletes and people who are physically active, as a support for body efficiency, processes of regeneration and lean muscle mass building. All the people who are exposed to harmful environmental conditions can use the product to help detoxify their body systems.
Moreover, this preparation is suitable for use during and after treatment of chronic diseases, infections, weakened immunity and in the periods of stress. It supports the liver functions and its regeneration during the periods when you use hepatocytes damaging agents.
This product is addressed for people who need to strengthen immunity, as well as those who are froced to large physical and intellectual efforts. N-Acetyl Cysteine can be used as a testosterone booster. Typically, the benefits of using NAC are noticeable in doses of 600-1800 mg per day, so the optimal dose is 2 capsules per day. Studies showed that NAC dose in the amount of 2800 mg per day for three months, in patients with COPD is rather safe.

Cysteine belongs to the group of essential amino acids, synthesized by the body, involved in detoxification of the body. The combination of L-cysteine with glutamine and glycine is involved in the synthesis of glutathione (a powerful antioxidant) and the proteins, enzymes and co-enzymes. Present in the protein product, in smaller amounts in corn and peanuts. The source of the acquisition are also concentrates and whey protein isolates, and preparations containing mixtures of amino acids. Not in the form mono-preparations. It is a component of detoxification, supporting the work of the liver supplements and in supplements improving the cosmetics of the body, usually in the form of L-cystine (two connected cysteine particles) or in the form of NAC.
Dosage: the usual supplementation: 50-500 mg per day.
