Uses & Effectiveness


N-acetylcysteine (NAC) is a derivative of the amino acid cysteine. It is used by the body to produce glutathione, a powerful endogenous antioxidant. NAC offers numerous health benefits, such as liver protection, a reduction of inflammation and enhancement of cognitive function.

NAC and cysteine are antioxidants in their own right, but they also stimulate the release of glutathione, a powerful antioxidant that fights inflammation and free radicals.

Listed below are the major health benefits, all of which are supported by scientific research.

N-acetylcysteine (NAC) is a powerful antioxidant that provides many health benefits, including glutathione formation. Glutathione is an important detoxifying agent in the body that helps protect cells from damage

Glutathione is the body's most important and most active antioxidant and is responsible for protecting against free radicals. It also regulates levels of nitric oxide, a powerful vasodilator that widens blood vessels so that more oxygen and nutrients reach tissues. 

Glutathione is also essential for the formation of adenosine triphosphate, a crucial source of fuel for our cells. But this does not happen on its own! Glutathione needs the support of some molecules to form, one of which is N-acetylcysteine (NAC). 

The human body is constantly under attack by viruses, bacteria and other foreign invaders. The immune system is the body's first line of defense against these threats. A strong immune system is essential to protect against internal and external attacks.

N-acetylcysteine (NAC) is a powerful antioxidant that helps support the immune system by neutralizing free radicals, which can damage cells and cause inflammation. NAC also helps increase levels of glutathione, another important antioxidant and immune booster.

NAC has been shown to protect against a wide range of diseases, including colds and flu. In one study, people who took NAC were 60 percent less likely to catch colds than those who did not. It also showed a reduction in the severity of cold symptoms, such as coughing and sneezing.

NAC is also effective in treating other respiratory conditions, such as bronchitis and asthma. In one study, people with bronchitis who took NAC experienced a 50 percent reduction in symptoms after only two weeks.

NAC is also being studied as a potential treatment for COVID-19, as it may help reduce the severity of symptoms. We publish here a selection of scientific articles on this topic from the FRI ZeroSpike medical-scientific committee.

The civic research project ZeroSpike was one of the first to discover as early as 2020 the health risks associated with the spike protein, a dangerous toxin that spreads in the body after SARS‑CoV‑2 infection and COVID "vaccination”. In 2021, a researcher at MIT Boston reached the same conclusions and described the main mechanisms of spike protein damage

In 2022, several physicians and scientists around the world have confirmed the role of the spike protein in the damage it causes to human health, even in fatal cases. An excellent article from January 2022, details THE 13 MECHANISMS OF SPIKE PROTEIN DAMAGE. 

The ZeroSpike medical-scientific team documented the abili ty of N-Acetylcysteine (NAC) to denature the toxic spike protein, an ability that was later demonstrated in vitro tests sponsored by the Civic Association. However, laboratory results showed a low rate of denaturation of the spike protein (12% in the latest tests conducted) by standard NAC, whereas Augmented NAC was always able to denature the spike protein above the 99% threshold. The in-vitro studies will soon be followed by in-vivo studies.

N-acetylcysteine (NAC) is an amino acid that offers numerous health benefits.

One of the most important benefits of NAC is its ability to improve gut health. The human gut is home to trillions of bacteria, many of which are beneficial. However, sometimes harmful bacteria can take over and cause problems.

NAC can help restore the balance of good and bad bacteria in the gut. It does this by increasing levels of glutathione, a powerful antioxidant that helps fight harmful bacteria. One study showed that NAC helps restore healthy populations of bacteria in people with inflammatory bowel disease (IBS). IBS is a condition characterized by abdominal pain, bloating, and diarrhea. Studies have shown that NAC can help reduce these symptoms.

Other research has found that it can help prevent unwanted bacterial infections, such as food poisoning. In addition, research shows that NAC may improve the Crohn's disease symptoms of ulcerative colitis. Furthermore, some evidence suggests that NAC may reduce inflammation throughout the body, helping to counteract the inflammatory effects of various factors, particularly a poor diet high in inflammatory foods.

Overall, NAC is a safe and effective food supplement that improves gut health and relieve symptoms of irritable bowel syndrome.

Numerous studies show that NAC has a positive effect on the respiratory system.

First, NAC has been recommended as a mucolytic for chronic and acute conditions affecting the respiratory tract. This is because it is able to break down mucus and dissolve phlegm that might obstruct the airways, thus allowing unobstructed breathing.

NAC helps increase glutathione levels and reduce inflammation in the lungs and bronchi. This can be a great relief, especially for individuals with chronic obstructive pulmonary disease (COPD).

COPD is associated with chronic inflammation of lung tissue that causes airway constriction with symptoms such as cough and shortness of breath.

NAC has been shown to prevent lung decline. In addition, the anti-inflammatory properties of NAC may help reduce coughing, wheezing, and respiratory attacks in chronic bronchitis.

Although NAC alone cannot reduce the incidence of cardiovascular disease, including it in a varied and balanced diet and healthy lifestyle can significantly reduce the risk of cardiovascular disease by promoting heart health through the protection of cardiac muscles from oxidative stress. Oxidative stress refers to the excessive production of reactive oxygen species or free radicals against antioxidant defense. This can cause cellular dysfunction leading to heart disease. 

NAC has been shown to promote the production of nitric oxide, which relaxes and dilates blood vessels, allowing blood to flow more freely and reducing blood pressure. This may reduce the risk of stroke and heart disease.

Another important benefit of NAC consumption is liver protection. The liver is a vital organ that filters toxins from the blood. NAC protects it from damage caused by toxins. It also helps repair damaged liver cells.

Because NAC has powerful antioxidant properties, it can help protect liver cells from damage caused by free radicals. Free radicals are unstable molecules that can cause damage to cells. They are a major contributor to aging and disease. Antioxidants such as NAC can help neutralize free radicals and protect cells from their damaging effects.

NAC replenishes glutathione and regulates glutamate, both of which promote brain function.

Glutathione is an antioxidant that reduces age-related oxidative stress in brain cells, while glutamate is a powerful excitatory neurotransmitter essential for learning and memory.

Alzheimer's disease, for example, reduces the ability to remember and learn. But research shows that NAC can counteract neurodegenerative conditions and offer neuroprotective benefits against dementia.

Another study that included NAC in standard treatment for Parkinson's disease showed improvement in mental and motor skills. Parkinson's disease is a brain disorder associated with the deterioration of dopamine-producing nerve cells. NAC works by restoring these nerves.

NAC is an amino acid that helps the body produce glutathione, a key antioxidant. It was found that it can help protect against diabetes and improve blood sugar control in people with the condition. 

High blood sugar levels destroy insulin receptors, causing insulin resistance, obesity, type 2 diabetes, and heart disease.

NAC may help improve insulin resistance, thereby facilitating proper glucose uptake by cells, keeping it in the normal range.

A recent study found that NAC can help improve insulin sensitivity and reduce fasting blood sugar levels in individuals with type 2 diabetes. Other studies have also found that NAC may help reduce A1C levels, which is a measure of long-term blood sugar control. NAC may also help increase insulin production in the pancreas, thereby improving blood glucose control. In addition, NAC has been shown to improve symptoms of diabetic neuropathy, a condition that can cause nerve pain and other problems.

If you are considering taking NAC to improve blood sugar levels, consult with your doctor first. NAC can interact with some medications, and it is important to make sure it is safe to take.

N-acetylcysteine (NAC) is a powerful antioxidant that has a wide range of health benefits. One of the lesser known benefits of NAC is its ability to promote fertility. NAC may help improve fertility in both men and women.

NAC can promote fertility in several ways. First, NAC can help improve egg quality. This is because NAC provides the body with glutathione, an important antioxidant that protects eggs from damage.

Second, NAC can help regulate hormones. This is important because hormone imbalance is a major cause of infertility. By regulating hormones, NAC can help increase the chances of conception

Third, NAC can improve blood flow to the reproductive organs. This is important because good blood flow is necessary for optimal fertility. Improved blood flow may also help reduce the risk of miscarriage.

Fourth, NAC can reduce stress levels. This is important because stress can have a negative impact on fertility. By reducing stress, NAC may help create an environment more conducive to conception.

One study found that supplementing NAC with selenium increased sperm quality.

Another study found that NAC may improve fertility in women with polycystic ovary syndrome (PCOS).

Overall, N-acetylcysteine offers a wide range of health benefits, including fertility promotion. If you are trying to conceive, consider adding Augmented NAC to your nutritional program.

NAC helps protect the eyes from damage caused by free radicals. Free radicals are unstable molecules that can damage cells and lead to disease. NAC helps neutralize free radicals and prevent them from causing damage.

NAC also helps to increase glutathione levels in the body. Glutathione is a substance that helps protect cells from damage, and since it is very present in the eyes, NAC can help keep the eyes healthy.

In addition, NAC has been shown to improve symptoms of dry eye syndrome and other eye problems. It can also help prevent cataracts and macular degeneration, two common age-related eye diseases.

NAC also helps improve vision by increasing blood flow to the retina.

Stress is a natural part of life and can be helpful when moderate levels are reached; however, excessive stress can lead to debilitating anxiety and depression. 

N-acetylcysteine (NAC) is an amino acid that offers many health benefits, including reduction of stress and anxiety. NAC helps increase levels of the neurotransmitter glutamate, which has calming effects on the brain.

NAC has demonstrated its effectiveness in reducing anxiety symptoms in animal and human studies. One study showed that NAC can reduce anxiety and improve mood in people with social anxiety disorder (SAD).

Another study found that NAC was able to reduce stress and anxiety in medical students during examinations, while another research paper found that NAC effectively reduced symptoms of post-traumatic stress disorder (PTSD).

NAC has also been shown to increase levels of the neurotransmitter GABA. GABA is responsible for calming the nervous system. By increasing GABA levels, NAC can help reduce stress and anxiety. Overall, NAC is a safe and effective way to reduce stress and anxiety. If you are feeling stressed or anxious, consider taking Augmented NAC.

Research has shown that NAC may help prevent some types of cancer. In particular, scientists are studying whether it may help prevent breast cancer and esophageal cancer when used alone or together with other treatments. In animal studies, NAC appears to protect against chemically induced tumors. Human research shows that NAC can reduce levels of estrogen and its metabolites in women who have had breast cancer. It also appears to reduce inflammation, which may be associated with several types of cancer.

One of the most well-known uses of NAC is the treatment of acetaminophen overdose. However, NAC can also help treat psychiatric conditions and ameliorate addictive disorders.

NAC shows promise as a treatment for psychiatric conditions such as schizophrenia and bipolar disorder. It may also help improve symptoms of anxiety and obsessive-compulsive disorder (OCD). NAC works by reducing brain inflammation and increasing levels of glutamate, a neurotransmitter that helps brain cells send and receive information.

In research, NAC has been shown to resolve symptoms associated with several psychiatric conditions such as schizophrenia, bipolar disorder, and obsessive-compulsive disorder.

NAC can also help treat addictive disorders, such as gambling, cocaine and nicotine addiction. In addition, it can help reduce cravings and withdrawal symptoms by reducing inflammation and oxidative stress in the brain.

One of the lesser known benefits of NAC is its ability to help people struggling with alcoholism.

NAC helps reduce cravings for alcohol and may also help reduce withdrawal symptoms. This is done by increasing levels of the neurotransmitter glutamate, which helps balance brain chemistry. 

NAC is also known for its ability to help protect the liver from damage caused by alcohol consumption. 

In addition, because NAC is a precursor to glutathione, the body's main antioxidant, it could potentially provide relief from alcohol-related oxidative stress. Oxidative stress occurs when free radical activity exceeds what our body's antioxidants can handle. This phenomenon is believed to be one of the causes of many common diseases.

A study published in 2013 on Alcoholism: Clinical & Experimental Research included 24 participants in mild to moderate alcohol withdrawal. Participants were given NAC or placebo for five days and then assessed daily with a standard clinical instrument measuring symptoms associated with alcohol withdrawal.

Results showed that subjects taking NAC had significantly fewer symptoms than those taking placebo.

In addition, participants taking NAC reported less anxiety during periods of acute withdrawal and had better sleep quality than those taking placebo.

Although more research is needed before NAC can be recommended as a treatment for alcoholism, these results suggest that people suffering from alcohol withdrawal may benefit from adding NAC supplements to their diet.

For people trying to quit drinking, NAC can be a powerful tool to combat cravings and withdrawal symptoms. It can also help reduce the risk of relapse into alcoholism. If you are struggling with alcoholism, talk to your doctor about whether NAC may be right for you.
