N Acetylcysteine

What Is NAC?

N-acetylcysteine (NAC) is a super helpful supplement that supports your complete health and boosts your body’s antioxidant defenses.

N-acetylcysteine (NAC) is a derivative of the amino acid cysteine. It has been used in medicine for many years due to its antioxidant properties and role as a precursor to glutathione, a critical antioxidant in the body.

NAC works primarily by increasing the synthesis of glutathione. Glutathione, in turn, plays a crucial role in reducing oxidative stress, detoxifying harmful substances, and maintaining the redox balance within cells.

Chemical Composition and Structure:

  • Chemical Name: N-acetyl-L-cysteine
  • Chemical Formula: C5H9NO3S
  • Molecular Weight: 163.19 g/mol

Structure: NAC consists of a cysteine molecule with an acetyl group attached to its amino group. This modification increases the stability and bioavailability of cysteine.

N-Acetylcysteine Uses and Benefits

Uses & Benefits


Antioxidant Support and Anti-Inflammatory Properties of NAC

N-acetylcysteine (NAC) is a strong antioxidant and anti-inflammatory agent. It treats diseases caused by oxidative stress and inflammation.

NAC helps increase glutathione levels, an important antioxidant in the body, which neutralizes free radicals and prevents cell damage.

Respiratory Health

NAC is often used to treat chronic respiratory issues like COPD and cystic fibrosis. It can help reduce mucus if you suffer from phlegm, bronchitis, colds, flu, cough, or breathing problems, making it easier to expel, and reduces lung inflammation.

Anti-Aging Benefits

As we get older, all parts of our body, including our skin, liver, heart, kidneys, and lungs, age. One cause of aging is oxidative stress, which occurs when we digest food and create energy, producing reactive oxygen species (ROS).

Antioxidants, especially glutathione produced by our liver, combat ROS. NAC boosts glutathione production, helping to reduce the effects of aging.

Protects Liver and Kidneys

NAC is known for its liver-protective benefits. It acts as an effective antidote for acetaminophen overdose by replenishing glutathione levels.

When the liver slows down, food particles can cause it to work harder and become sluggish, leading to skin pigmentation. NAC helps the liver process and eliminate toxins, heavy metals, and other harmful substances.

Lowers Anxiety and Depression

Studies show NAC can help treat psychiatric conditions like depression, bipolar disorder, and OCD, improve mood, and reduce anxiety and depression by balancing brain chemicals like glutamate.

It protects neurons from oxidative damage or inflammation by promoting glutathione production, supporting brain health, and potentially improving mood.

Helps with Metabolic Disorders

NAC can help manage metabolic disorders like hypertension, lipid problems, PCOS, insulin resistance, heart disease, dementia, non-alcoholic fatty liver disease (NAFLD), type 2 diabetes, high triglycerides, and excess body fat around the waist.


NAC has neuroprotective properties, as it can cross the blood-brain barrier, increase GSH levels in the brain, and reduce inflammation.

It may help protect brain cells and support cognitive function, potentially managing conditions like Alzheimer’s and Parkinson’s diseases.

Supports Pregnancy

NAC improves fertility by increasing insulin sensitivity. It enhances sperm quality in men, regulates ovulation, and improves egg quality in women.

By detoxifying the body, NAC creates a healthier environment for pregnancy.

Supports Gastrointestinal Health

NAC supports gastrointestinal health by reducing oxidative stress during stress, infection, and inflammation. It helps lower bacterial growth, prevent gastritis from Helicobacter pylori infections, and protect the gut lining from inflammation.

NAC also restores the intestinal barrier, improving gut function and easing conditions like inflammatory bowel diseases (IBD) and autoimmune gut issues.

Helps Fight Viral Infections

When a virus attacks, it replicates and affects our organs. Our body produces inflammatory cytokines to fight the virus, but excessive cytokines can cause organ failure. NAC helps regulate this process, supporting the body's ability to combat viral infections.

By boosting glutathione levels, NAC supports respiratory health, protects the liver, enhances mental health, and strengthens the immune system.

N-acetylcysteine (NAC) Dose

General Health- For general antioxidant support and maintenance of health, a typical dosage ranges from 600 mg to 1200 mg per day. NAC can be taken as one or two doses, depending upon the instructions as per the healthcare expert.

Specific Health Goals- For more targeted health benefits, such as liver support or respiratory health dosage of N-acetylcysteine (NAC) can go up to 1800 mg per day, usually divided into two to three doses.

When to take N-acetylcysteine (NAC)

With or without food- NAC can be taken with or without food, but some people find it easier on the stomach when taken with a meal.

Frequency- to get the most of N-acetylcysteine benefits take it once or twice at the same time each day.

N-acetylcysteine side effects & additional tips

Safe Dosage: It's safe to take 600 to 1800 mg of N-acetylcysteine (NAC) per day.

Side Effects: Some people might have mild side effects like nausea, diarrhea, headaches, and constipation. If this happens, try lowering the dosage.

Precautions: People with asthma or breathing problems should talk to a doctor before taking NAC.

Interactions: NAC can interact with some medications. If you're pregnant, breastfeeding, or have health issues, consult a doctor before starting NAC.
