N-Acetyl Cysteine, or simply  NAC, is a powerful antioxidant and semi-essential amino acid. It’s considered semi-essential because your body can produce it from other amino acids, namely methionine, and serine. It becomes essential only when the dietary intake of methionine and serine is low.

NAC is emerging as a promising integrative and natural treatment for women who are having complications from PCOS.

1️⃣ Improves Insulin Resistance
NAC has been emerging as a promising option for women with PCOS to improve their insulin levels. An important action of NAC is to protect insulin receptors and influence insulin receptor activity secretion from the pancreas cells. As a result, NAC can improve insulin resistance.

Several studies have compared NAC and metformin in women with PCOS. Women who took NAC showed similar results to metformin for improving insulin resistance as well as lowering cholesterol levels, and without experiencing the common gastrointestinal side effects that metformin can cause.

2️⃣ Restores Hormone Balance
A rather surprising and exciting benefit of NAC is that it has the potential to lower androgen levels and regulate menstrual cycles in women with PCOS. In one randomized controlled study, women with PCOS took either metformin (500 mg, three times daily) or NAC (600 mg three times daily) for 24 weeks. The results? both groups resulted in significant decreases in hirsutism score, free testosterone, and menstrual irregularity.

3️⃣ Boosts Fertility
A systematic review and meta-analysis published in the Journal of Obstetrics and Gynecology looked at the benefits of NAC in eight randomized controlled trials involving 910 women with PCOS. The review showed that NAC provided significant improvements for improving ovulation, pregnancy and live birth rates as compared to a placebo alone.

In a study published in the European Journal of Obstetrics, Gynecology, and Reproductive Biology found that NAC users had a nine times higher ovulation rate and five times higher pregnancy rate in Clomid resistant women than compared with a placebo.

4️⃣ Fights Inflammation
Women with PCOS have been shown to have higher levels of oxidative stress than women without PCOS. High levels of oxidative stress can damage the cells of your body and promote inflammation, which, in turn, can worsen the metabolic aspects of your PCOS. As a powerful antioxidant, NAC works to fight oxidative stress and reduce inflammation.

5️⃣ Helps Your Liver
On occasion, women with PCOS can develop non-alcoholic fatty liver disease. This type of fatty liver disease can result from high insulin and triglyceride (blood fat) levels but, can be reversed with modifications in your diet.

A study published in Hepatitis Monthly showed that women with PCOS who were treated with NAC (1200 mg/daily) for three months showed a significant improvement in lowering liver function tests, markers of fatty liver.
