N-Acetyl-L-Cysteine (NAC) is a more stable form of the amino acid L-Cysteine and is the most effective way to boost Glutathione levels in the body. NAC is a more stable form of L-Cysteine because it has an acetyl group (CH3CO) attached. NAC has all the properties of L-Cysteine but is more water soluble and said to be more bio-available than L-Cysteine.

NAC makes up Glutathione, a critical antioxidant scientifically proven to scavenge free radicals. NAC has the unique ability to maintain healthy lung tissue, support the body's natural defenses and enhance cellular health and longevity. These qualities make NAC especially beneficial for active people, the elderly and those exposed to polluted environments.

Helps with detoxification to prevent or reduce kidney and liver damage

N- Acetyl Cysteine plays an important role in the detoxification process in the body. It can help prevent drug side effects and environmental toxins

Produces Glutathione, a powerful antioxidant.

NAC is highly valued for its key role in antioxidant production. Along with two other amino acids, glutamine and glycine, NAC is essential for creating and replenishing glutathione.
Glutathione is one of the most important antioxidants, they help neutralize free radicals that can damage cells and tissues in the body. It is also essential for boosting the health of the immune system and fighting cell damage. Some researchers believe, it can even prolong life
Its antioxidant properties are important in fighting many other diseases caused by oxidative stress, such as heart disease, infertility and some mental illness.

Can improve mental disorders and addictive behavior

NAC helps regulate levels of glutamate, the most important neurotransmitter in the brain. While glutamate is essential for the normal functioning of the brain, an excess of glutamate coupled with a depletion of glutathione can cause brain damage. This can affect mental health conditions, such as bipolar disorder, schizophrenia, obsessive-compulsive disorder (OCD), and addictive behavior.
For people with bipolar and depression, N-Acetyl Cysteine can help reduce symptoms and improve overall functioning. Furthermore, research suggests that it may play a role in the treatment of moderate to severe OCD. Likewise, one animal study implied that NAC could mitigate the negative effects of schizophrenia, such as withdrawal syndrome, apathy, and distraction. NAC supplements may also help reduce withdrawal symptoms and prevent relapse in people addicted to cocaine. Additionally, preliminary studies suggest that NAC may reduce marijuana and nicotine use and cravings.

Helps relieve symptoms of respiratory conditions

NAC may relieve symptoms of respiratory-related conditions by acting as an antioxidant and releasing and loosening mucus in the airways. As an antioxidant, NAC helps replenish glutathione levels in the lungs and reduce inflammation in the bronchial tubes and lung tissue. People with chronic obstructive pulmonary disease (COPD) experience long-term oxidative damage and inflammation of the lung tissue that causes airways to become blocked, leading to shortness of breath and coughing. NAC supplements have also been used to improve symptoms of COPD and lung failure. In one year-long study, taking 600 mg of NAC twice a day significantly improved lung function and symptoms in people with COPD.

People with chronic bronchitis can also take NAC. Bronchitis occurs when the mucous membranes in the lungs, the bronchial passages become inflamed, swollen, and obstruct the air passages to the lungs. By thinning the mucus in the bronchial tubes and increasing glutathione levels, NAC can help reduce the severity and frequency of wheezing and coughing.
In addition to relieving COPD and bronchitis, NAC can improve other lung and respiratory conditions such as cystic fibrosis, asthma, and pulmonary fibrosis, as well as symptoms of nasal and sinus congestion caused by allergies or infections coincide.

Promotes Brain Health

NAC's ability to replenish glutathione and regulate glutamate levels may promote brain health. The brain neurotransmitter Glutamate is involved in a wide range of learning, behavioral and memory activities. While the antioxidant glutathione helps reduce oxidative damage to brain cells associated with aging. Because NAC helps regulate glutamate levels and replenish glutathione, it may benefit people with brain disease and dementia.
Neurological disorders, Alzheimer's disease can slow down learning and memory. Animal studies show that NAC can slow cognitive loss in people with Alzheimer's disease.
Another brain condition is Parkinson's disease, which is characterized by a decline in the cells that produce the neurotransmitter dopamine. Both oxidative damage to cells and reduced antioxidant capacity contribute to this disease. NAC supplements seem to improve both dopamine function and disease symptoms like tremors.

Improves fertility in both men and women

About 15% of all infertile couples are affected by infertility. In nearly half of these cases, male infertility was the major contributing factor. Factors leading to male infertility increase when antioxidant levels are not sufficient to combat free radical formation in the reproductive system. Oxidative stress can cause cell death and reduced fertility. In some cases, NAC has been shown to improve male fertility.
One condition that contributes to male infertility is varicocele. When the veins inside the scrotum became enlarged due to free radical damage and required surgery. Researchers suggest that NAC supplements should be considered a treatment option for male infertility. Additionally, NAC may improve fertility in women with polycystic ovary syndrome (PCOS) by inducing or increasing the ovulation cycle.

Helps stabilize blood sugar by reducing inflammation in fat cells

High blood sugar combined with obesity contributes to inflammation in adipose tissue. This can lead to damage or destruction of insulin receptors, increasing the risk of type 2 diabetes.
Animal studies show that NAC can stabilize blood sugar by reducing inflammation in fat cells and improving insulin resistance.

Reduces risk of heart disease by preventing oxidative damage

Oxidative damage to heart tissue often leads to heart disease, causing strokes, heart attacks, and other serious conditions. NAC may reduce the risk of heart disease by reducing oxidative damage to tissues in the heart. It has also been shown to increase nitric oxide production, which helps dilate veins and improves blood flow. This helps speed blood flow back to the heart and can reduce the risk of a heart attack. One test-tube study found that, when combined with green tea, NAC seemed to reduce damage from oxidized LDL cholesterol, another factor in heart disease.
