NAC Supplements Australia: The Top 7 NAC Supplement Benefits 

Recent studies indicates that N-acetyl cysteine (NAC), a nutrition supplement form of L-cysteine, is an effective, safe, and low-cost health treatment option for a variety of health conditions, both acute and chronic.

What are the benefits of taking NAC?

Health benefits of NAC

Not only has it been utilized as an efficient mucolytic agent (mucous-thinner) for three decades, but it also has benefits such as lowering inflammation, preserving the liver, and preventing/treating medication toxicity, insulin resistance, PCOS infertility, and many other health benefits. 

What Exactly Is N-Acetyl cysteine?

Why should you use it?

N-acetyl cysteine (NAC), a supplement form of cysteine, is an amino acid that aids the body in the production and utilization of beneficial antioxidants.

While cysteine can be found in a variety of high nutrition, high-protein health foods, NAC can only be accessed through supplements or prescription medicines.

NAC is classified as a "semi-essential amino acid" since the human body can synthesize some of it from other amino acids, mainly methionine and serine. That is, there is no daily NAC minimum that you must meet through your nutrition and diet, although higher levels can assist some people's health.

Is N-Acetyl cysteine good for your health?

  1. N-acetyl cysteine is considered to be a functional medicine Australia
  2. Increasing the glutathione antioxidant levels
  3. Acetaminophen treatment (a class of painkillers overdose)
  4. Breaking up mucus in patients with certain lung conditions, such as chronic bronchitis
  5. Protecting the liver
  6. Assisting in the prevention of bladder or brain damage induced by some medicines
  7. Possibly aiding in the prevention of colon cancer
  8. Possibly aiding in the prevention of colon cancer Improves gut health nac

Top 7 Advantages

1. Has anti-oxidant properties and aids in the formation of Glutathione

NAC is involved in the glutamatergic system's regulation. In other words, NAC (together with glutamine and glycine) is an amino acid that is required to make what is considered the most essential antioxidant in the human body, glutathione, as a precursor of L-cysteine, which results in glutathione production.

The antioxidant and anti-inflammatory properties of N-acetylcysteine are the most important health mechanisms of action. This is because of its capacity to boost glutathione levels, scavenge free radicals, minimize oxidative stress and improve health through nutrition intervention. 

As a result, it is indicated as a potential treatment for a variety of poor health ailments caused by free oxygen radicals, including liver disease, Alzheimer's, Parkinson's, and even cancer. This treatment represents advanced functional medicine.

2. Can Aid in Pregnancy Outcomes

Is N-acetyl cysteine safe to use when pregnant?

NAC therapy has been found in studies to have no negative effects on either the health of the mother or the fetus. 

Certain studies have even shown that NAC, when combined with vitamin E, or vitamins A+E, and essential fatty acids, can lower reactive oxygen species (ROS) and enhance natural conception rates in women who are having health related difficulty becoming and staying pregnant, particularly those with PCOS.

This is because it raises levels of the antioxidant glutathione, which boosts insulin production and lowers insulin resistance, both of which are linked to PCOS. Improving patients specialties health outcomes.

NAC appears to work as a treatment technique to enhance the amount of circulating insulin as well as insulin sensitivity in PCOS patients with hyperinsulinemia, according to a study published in Women's Health Reviews.

NAC also contains anti-inflammatory properties that can improve pregnancy health and birth outcomes in women with infections who are predisposed to preterm labour. After week 16 of pregnancy, doses of roughly 0.6 gram of NAC administered orally together with progesterone can protect against recurrence of preterm birth.

It can also be used to treat acetaminophen overdose during pregnancy, which is the most common drug overdose among pregnant women.

3. Assists in the treatment of respiratory issues by breaking up Mucus.

NAC has the capacity to reduce mucus discharges and phlegm, as well as coughing, wheezing, and breathing difficulties. This makes it useful in the treatment of illnesses such as chronic bronchitis (defined as the presence of chronic productive coughs for more than three months in two consecutive years), colds, and the flu.

Furthermore, there is evidence that it can be used as an adjuvant health treatment for COPD (the fourth highest cause of mortality in the United States) and emphysema.

4. It safeguards the liver and kidneys.

What role does N-acetyl cysteine play in aiding health detoxification? 
Aside from protecting the organs from free radical damage, it can also help manage the negative effects of certain medications/drugs, particularly acetaminophen.

The current view is that NAC is an excellent treatment for acetaminophen intoxication and acute liver failure.

NAC injections can be used to mitigate the negative effects of overdose on the liver and kidneys. It appears to mitigate chemical toxicity in numerous ways:

Firstly, because of its dual role as a nucleophile and a -SH donor by replenishing glutathione by decreasing N-acetyl-pbenzoquinonimine and performing hepatoprotective effects due to its antioxidant qualities.
It is most effective in reducing toxicity when taken within eight to ten hours of an overdose. Patients who take NAC within eight hours usually recover quickly and have less than a 10% probability of developing hepatotoxicity, as well as a minimal risk of developing major liver/kidney damage.

5. It has mood-lifting/stabilizing health properties.

A glutamate imbalance is thought to be one mechanism contributing to mood and cognitive disorders. NAC may be an effective natural nutrition supplemental treatment for anxiety, depression, and other mental health issues because it affects levels of the neurotransmitter glutamate in the brain.

It has been demonstrated to have a good treatment influence on psychiatric illnesses defined by either oxidative stress or impulsivity and compulsivity.

According to an article published on the website Psychology Today:

This compound has been studied extensively, including neuroimaging studies, and it has been studied in a wide range of illnesses, including depression, bipolar disorder, OCD, PTSD, schizophrenia, addiction, eating disorders, Alzheimer's disease, and addiction.

While more research is needed to understand how NAC works in the brain, there is evidence that NAC may aid with ruminations (difficult-to-control extreme negative self-thoughts). It can assist in making these thought patterns less stressful and less likely to elicit major concern or panic, as well as create depression.

6. May Aid in the Prevention of Cancer Development

Although not proven to be a cancer health treatment, there is evidence that NAC can protect against cancer by neutralizing free radicals that cause DNA damage. In animal experiments, animals administered NAC had less cellular damage and fewer lung, colon, and bladder cancers than those fed a standard natural diet.

According to the Memorial Sloan Kettering Cancer Center, "NAC inhibits tumour invasion, metastasis, and blood vessel formation in lab trials, although it is unknown how well these effects translate to the health of patients."

Clinical studies view that NAC supplements can help protect against some types of cancer in a variety of ways. These are some examples:

Improving antioxidant and vitamin status through modulating the expression of genes involved in oxidative stress and inflammation pathways decreases the synthesis of inflammatory cytokines and proteins
It can also be used to help cancer patients overcome the side effects of certain medications and natural treatments.

7. Prevents Metabolic Disorders

As previously stated, NAC supplements enhance insulin sensitivity and can aid those who are predisposed to developing metabolic diseases.

N-Acetyl cysteine review & Natural Ways to Increase Levels

N-Acetyl cysteine: How to Use It (and Dosage Information)

NAC is an over-the-counter nutrition supplement that can be acquired in capsule/tablet form at your local health food store. It is also available as an injectable on prescription.

While cysteine (a sulfur-containing amino acid) can be found in natural meals such as chicken, turkey, various meats, garlic, yoghurt, and eggs, NAC can only be obtained from health supplements or medications.

There is no view of an accepted "optimal dose" for NAC supplements or a daily requirement for NAC. Experts advise to add a suitable dose for several months and carefully tracking its impact on major health symptoms - this way, you'll know if it's working and how much you need.

The following are general NAC dose recommendations based on the symptoms/conditions being treated:

A daily dose of 600-1,800 milligrams of NAC appears to be useful and natural against various health conditions; add 600-milligram capsules taken two to three times a day is the recommended starting dose.

According to research, 2,000 milligrams is safe for most adults.

To treat certain chronic and degenerative health conditions, such as COPD, poor glycemic control, and cancer, higher doses may be required. According to some research, dosages of around 2,800 milligrams per day for up to three months appear to be beneficial for persons with COPD.

How long does it take to work?

This is determined by the condition being treated, the individual, and the dosage of supplements administered.

When you add an administered intravenous drip, it can help alleviate overdoses and toxicity within hours. Other conditions may take several months to improve health metrics, while it may improve in a matter of weeks for some people.

Should you take N-Acetyl cysteine supplements in the morning or at night?

It can be taken at any time of day that is convenient for you. 
NAC supplements come in 500, 600, 750, and 1,000 milligram strengths. To notice positive health effects, you will most likely need to divide your supplement dose and take it two or three times daily, so consider taking it once in the morning and once at night. 

Risks, Adverse Reactions, and Interactions is N-Acetyl cysteine dangerous?

While it is generally considered natural and safe to add NAC supplements for health purposes, some drug interactions and adverse reactions are possible. Overall, most experts view that when you add NAC, the supplement has the potential nutrition and health benefits that outweigh the hazards.

What are the negative side effects of N-Acetyl cysteine?

Possible side effects include:

Stomach ache/indigestion

Diarrhoea, exhaustion, and drowsiness

Skin rash caused by perspiration

If you view any of these apply to you, see your doctor before taking NAC supplements to discuss any potential health benefits or negative health interactions. This should be the view taken when consuming any vitamin.

Is N-Acetylcysteine toxic to the kidneys or liver?

In very high doses, every supplement has the potential to add to liver or kidney health problems; nevertheless, as previously stated, NAC supplements are typically regarded as protective of the liver and kidneys, rather than harmful to them. Always be cautious when commencing any new herb or vitamin.


Is NAC banned in Australia? Is it still for sale? Can you buy it?

While there had been a political shift in the US, which seemed to influence the FDA to abruptly re-evaluate their view on the status of NAC supplements to that of a medicine. Despite its having a history of supplemental benefits spanning more than 2 decades. This was ultimately seen as a response to the claims and research emerging that NAC could treat Coivd 19.

Thankfully Australia and the TGA did not take this view and were much more sensible and did not feel the need to add to a banned list or re-classify NAC supplement in Australia for Covid use.



If you are unsure about when to add any health supplements or vitamin we suggest consulting a licensed medical professional for expert advice.
