N-acetyl cysteine for healthy lungs

Content of the article

NAC - what it is and what it can do:

NAC, or N-acetyl cysteine, is a naturally occurring amino acid with strong antioxidant properties. It plays a key role in the body's natural defense against oxidative stress and inflammation, and has been used for decades to treat a variety of conditions. In recent years, researchers have discovered that NAC also has a regulatory effect on the immune system by improving oxygenation and blood flow to granulocytes - cells that play a key role in the body's defense against infection. Therefore, NAC may be beneficial for people with certain immune-related conditions, including chronic viral infections and autoimmune diseases. In addition, research has shown that taking NAC can help improve symptoms of respiratory diseases.

What are the functions of N-acetyl-cysteine in the body?

NAC regulates the immune system

NAC helps regulate the immune system by improving oxygenation and blood flow to granulocytes, a type of white blood cell. These cells play an important role in the defense against bacteria and fungi, as well as other pathogens. These cells have special receptors that enable them to recognize foreign invaders and react quickly by releasing chemicals that destroy the invaders.

NAC known expectorant and more

The expectorant properties make NAC a popular choice for people with respiratory conditions such as bronchitis, asthma and COPD.

However, NAC can do much more for the respiratory tract than just rid it of mucus. The lungs are constantly exposed to germs, particulate matter and environmental toxins, which can lead to oxidative stress and associated inflammation. NAC, with its antioxidant, anti-inflammatory and expectorant properties, provides ideal protection for the lungs. In addition, NAC supports the body's glutathione production (see the article about glutathione), which is of great importance for lung and immune functions.

NAC as a help for depression

NAC has been shown to help with mood and anxiety disorders such as depression, bipolar disorder, obsessive-compulsive disorder and more. Research suggests that NAC may help modulate the activity of certain neurotransmitters, which can have a positive effect on mental health.

NAC for healthy liver function

NAC promotes healthy liver function by providing strong antioxidant and anti-inflammatory properties. It helps reduce oxidative stress in the liver, which can lead to damage to the organ and other associated conditions such as fatty liver. NAC's antioxidant properties also help protect cells from free radical damage, while its anti-inflammatory properties can reduce inflammation.

NAC for pain relief in autoimmune diseases

NAC has been shown to relieve chronic pain associated with rheumatoid arthritis and other autoimmune diseases. This is due to its antioxidant and anti-inflammatory properties, which help reduce oxidative stress in the body. Oxidative stress can lead to inflammation, which is a major factor in chronic pain associated with these conditions.

NAC supports the detoxification processes in the body

NAC is known for its powerful detoxification properties, as it can support the body's natural elimination of toxins and waste. NAC helps the liver and other organs break down and neutralize toxic compounds so they can be more easily eliminated from the body.

NAC supports a healthy brain

NAC is a powerful antioxidant that can support brain health in a variety of ways. Research suggests that NAC has the potential to improve cognitive function, reduce anxiety, and even protect against neurodegenerative diseases like Alzheimer's.

One of the main ways NAC supports brain health is through its ability to increase levels of certain neurotransmitters. Neurotransmitters are important for cognitive functions such as memory, attention, emotions and motivation. Studies have shown that NAC can boost the production of serotonin and dopamine.

How much NAC should be taken daily?

The recommended daily dose of NAC is 500 - 1000 mg per day. This daily dose is considered safe and has been tested in various studies, including in people with rheumatoid arthritis and other autoimmune diseases. Taking more than this amount may cause adverse side effects such as nausea, vomiting, headache, and diarrhea.

NAC naturally in food?

Fortunately, NAC occurs naturally in some foods! Foods like broccoli, cauliflower, kale and Brussels sprouts are rich in NAC. Eating these vegetables regularly can help you reap the benefits of this powerful antioxidant.

8 foods that contain NAC


0.41 mg/100 g


0.34 mg/100 g

A balanced diet with plenty of fruits and vegetables is important for overall health, but it can be difficult to get all the nutrients your body needs.

Taking a NAC supplement is an easy way to ensure that you are getting enough of this powerful antioxidant in your diet. By taking NAC regularly, you can get the full range of benefits without having to worry about eating certain foods or making sure you're consuming enough NAC each day.


NAC supplements - our recommendation

NAC for the elimination of graphene oxide

NAC, like glutathione, helps to eliminate graphene oxide from the body.

For this, one capsule of NAC (750 mg) is taken, which causes the body to release glutathione endogenously, i.e. from the body itself, which in turn increases the glutathione level in the body. It is best to take it in the morning on an empty stomach, as this is the quickest way for the body to absorb the substances, this applies to all of the following substances, except for melatonin.

In addition to NAC, zinc should also be taken.

In addition, the intake of astaxanthin (5 mg), quercetin as well as vitamin D is recommended.

As a stomach and liver protection can milk thistle (an antioxidant and glutathione booster) can be taken. And as a protection against radiation is suitable to take melatonin in the evening. Melatonin also supports healthy sleep, which is essential for a healthy body.
