BASIC INFORMATION

NAC is the supplemental form of  the amino acid l-cysteine ( a critical amino acid for our health ) NAC aids in replenishing glutathione, which is the most important antioxidant in the body. Antioxidants help neutralize free radicals which damage cells and body tissues.  NAC is the supplemental form of  the amino acid l-cysteine ( a critical amino acid for our health ) NAC aids in replenishing glutathione, which is the most important antioxidant in the body. Antioxidants help neutralize free radicals which damage cells and body tissues.  

N-acetyl-cysteine, or NAC, is derived from the amino acid L-cysteine. Consuming adequate amounts of cysteine is critical to our health. One of the body’s most important antioxidants, glutathione, helps neutralize free radicals that can damage cells and tissues within the body. It is essential for immune health and for fighting off damage at the cellular level. NAC helps to replenish the glutathione in our bodies. It acts as a hepatoprotective agent by restoring hepatic glutathione, serving as a glutathione substitute. Cysteine is an antioxidant found in high-protein foods, such as chicken, turkey, yogurt, cheese, eggs, and legumes. NAC is the supplement form of cysteine. It is used to help many conditions, such as flu, dry eye, and kidney disease. It is used for cough and other lung conditions due to its antioxidant and expectorant properties of loosening the mucus in your airways and reducing the inflammation in your bronchial tubes and lung tissue. It is also used in emergency rooms to treat Tylenol® overdose. NAC helps in the regulation of glutamate, a neurotransmitter responsible for sending signals between the brain and nerves in the body. In conditions such as addiction, NAC may help with withdrawal symptoms and relapse.

USES

Endocrine ( infertility, androgen support, adrenal support ) Immune health (  liver detoxification, replenishes glutathione levels ) Mood Health ( addictive behavior, psychiatric diseases such as depression, bipolar disorder, schizophrenia and OCD ) Respiratory health ( mucolytic agent ) 

BENEFITS

Endocrine/Thyroid/Energy:

NAC can promote/improve androgen production (i.e. testosterone), accelerates antioxidant activity in the thyroid gland which helps support thyroid conversion/utilization and supports adrenal function. Improves PCOS symptoms and can improve androgen hormone utilization. NAC has also been found to help improve fertility as it plays an important role in germ cell survival.

Immune Health: 

NAC is a precursor to glutathione production, glutathione is the body's master antioxidant. It also supports liver detoxification.

Mood Health:

It is also thought that N-acetyl cysteine may improve psychiatric disorders such as depression, bipolar disorder, schizophrenia, and obsessive-compulsive disorder and addictive behaviors as well. NAC helps in the regulation of glutamate, a neurotransmitter responsible for sending signals between the brain and nerves in the body. In conditions, such as addiction, NAC can help decrease withdrawal symptoms and relapse.

Respiratory Health:

NAC can help treat respiratory conditions as well. N-acetylcysteine acts as an antioxidant and expectorant by loosening the mucus in your airways and reducing the inflammation in your bronchial tubes and lung tissue.

Addiction:

NAC is thought to improve symptoms and addiction in patients with cannabis use disorder/cannabinoid hyperemesis syndrome.

Gut Health:

Ulcerative colitis is a chronic inflammatory disorder which multiple casual factors can affect it. Human colitis has many similar characteristics to acetic acid (AA)-induced colitis, as a reproducible and simple model. Studies have indicated that some signaling pathways contributing in cell apoptosis and growth, angiogenesis, redoxregulated gene expression, and inflammatory response can be affected by NAC. Therefore, NAC may not only protect against the direct detrimental impacts of oxidants, but also advantageously modify inflammatory events in colitis (34). The beneficial influences of NAC were related to the changes including: Softened colonic injury,. Decreased oxidative stress,  Lowered cell apoptosis, Increased recovery of the injured colon, and increased formation of the tight junction.

Muscle Performance:

Investigations showed no effect of NAC on non fatigued muscle, although after three minutes of repetitive contractions, it caused a considerably enhanced force output, up to approximately 15%. This means that NAC can improve muscle performance. This result originated from the fact that oxidative stress plays a causal role in the fatigue process, since NAC is a scavenger of free radicals causing oxidative stress. It has been well reported that infusion of NAC can be effective in enhancing the overall redox status in vivo. It has also been shown that NAC infusion could minimize muscle fatigue.

Parkinson Parkinson disease (PD) 

Is a very prevalent neurodegenerative disorder caused by unknown deterioration of cells which generate dopamine in the pars compacta, a part of the substantial nigra located in the midbrain . In terms of pathogenesis, PD appears to be a multifactorial disorder, including environmental factors, acting on genetically vulnerable individuals when they are older. A wide range of both genetic and environmental factors have been proposed as contributing to the initiation and progression of PD, but aging is the single most important risk factor for this disorder and undoubtedly interferes in PD progression through its accumulative oxidative damage, decrease in antioxidant ability and impairment of mitochondrial bioenergetic capacity in the brain . Taking into account that most PD patients experience accumulative oxidative damage, some clinical studies have demonstrated the controversial effect of some antioxidant administrations -such as NAC- on treatment of PD. Some improvements have been reported for systemic administration of NAC in animal models, such as: i. Enhancement of brain level of glutathione, ii. Reduction of oxidative damage-markers, iii. Enhancement of brain synaptic and non-synaptic brain mitochondrial complex I activities, and iv. Protection against dopamine-induced cell death.

Alzheimer disease (AD)

Is known as a multifactorial disease with many abnormalities in physiological, biochemical, and neurochemical point of view. Aging is the major risk factor for AD that coexists with other causes of cognitive decline, particularly vascular dementia. Some factors, such as mitochondrial dysfunction, abnormal protein aggregation, metal accumulation, inflammation and excitotoxicity play important roles in AD pathology. Although the relationship between these factors and development of AD is multidirectional, oxidative damage is considered as a common thread linking some of these factors . Results of different studies showed that lipoic acid (LA) and NAC decreased levels of oxidative and apoptotic markers via protection of mitochondrial function. Combination of both LA and NAC maximizes this protective effect suggesting that this may prevent mitochondrial decay associated with aging and age-related disorders such as AD. Antioxidant therapies based on LA and NAC seem promising since they can act on mitochondria, one key source of oxidative stress in aging and neurodegeneration .

Asthma 

Is a chronic disorder associated with inflammation and immune cell infiltration of airways. Airway hyper-responsiveness (AHR) can be originated from the consistent presence of inflammatory mediators and immune cells in airways. AHR is clinically determined with breathlessness, coughing and wheezing symptoms. Studies showed the preventive effect of NAC antioxidant on the AHR and steroid resistant accumulation of inflammatory cells in the airways of the animal model with acute exacerbation of asthma

SIDE EFFEICTS / PRECAUTIONS

NAC is generally safe for most adults. Women who are pregnant or breastfeeding are also typically safe when taking NAC, but should always speak with their healthcare provider before taking. Some drugs may interact with NAC. One major interaction is with nitroglycerin. Nitroglycerin dilates the blood vessels and increases blood flow. NAC tends to increase the effects of nitroglycerin, possibly causing increased side effects, such as headache, dizziness, and lightheadedness. Another drug that moderately interacts with NAC is activated charcoal.
