Anxiety is a common mental health issue that affects millions of people worldwide. It can range from mild to severe and can interfere with daily life. While there are several treatments for anxiety, NAC (N-acetylcysteine) is gaining popularity as an effective and natural way to combat anxiety. In this blog post, we’ll explore what NAC is and how it can help combat anxiety.

What is NAC?

NAC is an amino acid that is naturally found in the body. It is a precursor to glutathione, a powerful antioxidant that helps protect the body against free radicals. NAC is also used as a medication to treat acetaminophen (paracetamol) overdose and to loosen mucus in the lungs of people with respiratory conditions like cystic fibrosis. Recently, researchers have discovered that NAC may also be effective in treating anxiety.

N-acetylcysteine (NAC) is a dietary supplement that has gained attention as a potential treatment for anxiety. NAC is an antioxidant that helps to reduce oxidative stress in the body, which can contribute to anxiety and other mental health disorders. It also has been shown to modulate the levels of glutamate, a neurotransmitter that plays a role in anxiety and stress. Several studies have suggested that NAC may be effective in reducing symptoms of anxiety and improving overall mental health, although more research is needed to fully understand its mechanisms of action and long-term effects. As with any supplement or medication, it’s important to talk to a healthcare provider before starting to use NAC for anxiety.

How does NAC work?

Researchers believe that NAC may help combat anxiety by regulating glutamate, a neurotransmitter in the brain. Glutamate is responsible for stimulating the brain and is linked to anxiety when levels are too high. NAC helps regulate glutamate by increasing the production of glutathione, which can reduce the levels of glutamate in the brain. This can help alleviate symptoms of anxiety.

Studies on NAC and Anxiety

Several studies have been conducted on the effectiveness of NAC in treating anxiety. In a randomized controlled trial, participants with generalized anxiety disorder were given either NAC or a placebo for 12 weeks. The study found that those who received NAC had a significant reduction in anxiety symptoms compared to the placebo group. Another study found that NAC was effective in reducing symptoms of obsessive-compulsive disorder (OCD).

How to Take NAC

NAC is available as a supplement and can be found at health food stores and online retailers. It is recommended to take NAC under the guidance of a healthcare professional. The recommended dosage for anxiety is typically 600-2400 mg per day, divided into two or three doses.


Anxiety can be a debilitating condition that affects many people. While there are several treatments available, NAC is gaining popularity as an effective and natural way to combat anxiety. Research suggests that NAC may work by regulating glutamate in the brain. Several studies have shown that NAC is effective in reducing symptoms of anxiety and OCD. If you’re interested in trying NAC, be sure to talk to your healthcare professional first to determine if it’s right for you.
