According to research, NAC supplements are potential compounds for synthesizing antioxidants inside your body (2). Research indicates the role of NAC as a building block of glutathione, an antioxidant.
NAC has been used to treat medical conditions such as acetaminophen overdose and as a dietary supplement for decades (3). With FDA approval in certain cases, it is making its way through the market due to its numerous other benefits associated with human health.
How Does NAC work? Cells undergoing oxidative stress due to increased free radical/reactive oxygen species can lower levels of the body’s antioxidant, glutathione (GSH), or its precursor cysteine. Due to their reduced levels, cells are more vulnerable to damage from oxidation (4).
However, with NAC, you’ve got nothing to worry about. This is because N-acetyl-cysteine is considered a pro-drug of cysteine. After consuming NAC orally, it is sent to the liver via a portal route after going through the gastrointestinal tract.
NAC is converted to cysteine almost entirely inside the liver for its subsequent transition into GSH.
GSH is distributed to the body cells as soon as it gets released into the bloodstream. It is worth noting that free NAC levels inside plasma are very low due to its extensive first-pass metabolism in the liver.
Benefits of NAC NAC is medically used to treat acetaminophen overdose. Within 8 hours of overdose, NAC is seen to be 100% effective in saving lives. Thus, medically NAC is extremely relevant.
Besides this, NAC is seen to ameliorate symptoms of bipolar disorder, schizophrenia, and obsessive-compulsive disorders.

Women with PCOS often suffer from insulin sensitivity and increased blood glucose. However, with NAC, you can control the latter condition (7). Nonetheless, the exact mechanism behind this is still unclear.
Importantly, NAC plays a wide role in phase II of the detoxification process occurring in the liver. The antioxidant attribute of NAC, via increased glutathione levels, can aid liver function and detoxification.
This is just not it! NAC may also be used to fight disorders like gambling addiction, excessive nicotine dependence, skin biting, and alcohol use disorder.
Is NAC Legal? This one is a complicated question to clear out. NAC supplements are FDA approved to be used as an intravenous treatment in conditions such as acetaminophen overdose or breaking up excess mucus via inhaled treatment.
Other than that, the FDA has not yet decided on NAC to be used as a dietary supplement. Due to this, many companies have stopped selling NAC altogether, while others market it as an OTC supplement.
Who Should Use NAC? NAC supplement can be used by almost anyone looking to help detoxify, improve liver function, fight psychiatric disorders, or minimize increased blood glucose levels. It is also used in hospitals to treat patients with acetaminophen overdose and chronic lung disease.
However, due to its potential side effects leading to skin rashes, vomiting, diarrhea, eye irritation, and fatigue, one should avoid supplementing it if they are susceptible. It may be a contraindication in people with skin allergies or sensitive bowels.
How to Use NAC? NAC supplements require an optimum temperature in a cool, dry room. It is important to note that NAC may contain an odor similar to that of sulfur, which is completely normal.
As for the appropriate dosage of NAC, remember it is not FDA approved; however, most NAC supplements can be sold in 500 mg to 1200 mg. Splitting your supplement into 1 to 4 doses per day is recommended for safety concerns.
