Description

NAC is both an antioxidant and amino acid (building blocks of protein). Specifially, NAC is a derivative of the amino acid L-cysteine, an essential precursor used by the body to produce glutathione. Glutathione is an extremely important and powerful antioxidant produced by the body to help protect against free radical damage, and is a critical factor in supporting a healthy immune system.

Research shows that women with Polycystic Ovary Syndrome (PCOS) have higher levels of oxidative stress which can contribute to ovarian dysfunction and hormone imbalance. Oxidative stress occurs from free radical or cell damage. As a powerful antioxidant, NAC works to increase glutathione to neutralize or repair damaged cells.

NAC is widely sold in Europe as a treatment for the common cold and it has other numerous uses from being a treatment for bronchitis to removing heavy metals and environmental pollutants from the body. NAC has also been found to reduce inflammation, heart disease and most recently, insulin.

NAC may help:*

  • Improve insulin resistance
  • Lower cholesterol levels
  • Improve non-alcoholic fatty liver disease
  • Protect against free radical damage and oxidative stress
  • improve  pregnancy and ovulation
  • Provide Immune support
  • Aid in detoxification

NAC vs. Metformin in PCOS

Two studies have compared the effects of NAC or Metformin in women with PCOS.

In the most recent study published in Gynecological Endocrinology, a randomized double-blind clinical trial involving 94 women with PCOS compared NAC 600 mg, three times a day with 500 mg oral metformin, three times a day for 24 weeks.

The researchers found that NAC can improve lipid profile and fasting blood sugar and fasting blood insulin better than metformin.

These results are confirmed with an earlier study, published in the European Journal of Obstetrics, Gynecology and Reproductive Biology which compared the effects of NAC and metformin on insulin levels. In this prospective trial, 100 women with PCOS were divided to receive metformin (500mg three times daily) or NAC (600mg three times daily) for 24 weeks.

Both treatments resulted in a significant decrease in body mass index, hirsutism, fasting insulin, free testosterone and menstrual irregularity.

Both treatments had equal effectiveness. Furthermore, NAC led to a significant decrease in both total cholesterol and low-density lipoprotein levels, whereas metformin only led to a decrease in total cholesterol level.

This research supports findings published in the Journal of Fertility and Sterility in 2002 where researchers reported significant improvement in insulin levels among women with PCOS who took 1.6-3g/day of NAC and who had elevated insulin levels before the start of study. Women also showed improvements in testosterone, cholesterol and TG levels.

NAC and Fertility in PCOS

When used with clomid, NAC has been shown to improve ovulation and pregnancy rates in PCOS women by thickening endometrial thickness. 100 women with PCOS who randomly received NAC plus clomid had more endometrial thickness and ovulatory follicles than women who just took clomid or clomid plus metformin.

NAC was also shown to improve oocyte and embryo quality in Iranian women undergoing intracytoplasmic sperm injection.

In a systematic review and meta-analysis involving eight randomized controlled trials with 910 women published in Obstetrics and Gynecology, showed that NAC had significant improvement in pregnancy and ovulation rate as compared to placebo.

Side Effects

Overall, NAC is well tolerated but can cause gastrointestinal adverse effects including nausea, abdominal pain, vomiting, constipation, and diarrhea, particularly when used in high doses. The therapeutic dosage of NAC to improve insulin levels based on published studies is 1.6-3 grams/day. If you are overweight, you may benefit from the higher end of the dose range. Fulghesu et al found that obese patients with PCOS did not respond to doses under 3 grams/day. You should not exceed 7grams/daily. As with any nutrition supplement, it is important to discuss use with your physician before taking.
