The Power of NAC: Improving Fertility, Heavy Bleeding and PCOS

AC Benefits for Fertility, PCOS, & More

NAC (N-Acetyl Cysteine) is an easily-absorbed form of the amino acid L-cysteine with powerful antioxidant properties, used as a dietary supplement to treat respiratory, liver and psychiatric disorders.

NAC (N-Acetyl Cysteine) is a supplement used to empower women with heavy bleeding, fertility issues, and hormone-related conditions. It is an amino acid form of cysteine that boosts liver detox, aiding in breaking down estrogen when in excess, which is often a source of hormonal symptoms.

NAC benefits your hormonal health by supporting:

  • Ovulation and fertility
  • Liver and kidney detoxification 
  • Healthy hormone balance
  • Insulin resistance

NAC can help boost fertility by promoting ovulation and healthy egg growth, as well as improving ovarian function. NAC has been found to be an effective supplementary treatment for unexplained female infertility, especially among those who have high BMI, insulin resistance and oxidative stress. Further research is needed to further confirm this.


PCOS (Polycystic Ovarian Syndrome) is an endocrine disorder characterized by elevated levels of androgens (male hormones) in women. This hormonal imbalance can lead to a range of symptoms such as irregular periods, acne, weight gain, and excessive hair growth, as well as interfere with fertility through the disruption of ovulation.

Studies have found NAC (N-Acetylcysteine) to be an effective treatment for PCOS. It has been shown to boost insulin sensitivity, which is often impaired in women with PCOS, improve fertility by increasing ovulation, and reduce oxidative stress. Insulin resistance is a common feature of PCOS and can lead to high levels of insulin in the body, which can contribute to hormonal imbalances.

In summary, NAC supplementation may be an effective way to address hormonal balance in women and increase their chance of becoming pregnant. More research is needed to further confirm these effects.

NAC for Fertility

Fertility can be impacted by oxidative stress, an imbalance of free radicals and antioxidants in the body leading to cell/tissue damage, which can cause issues with sperm quality and ovarian function, resulting in infertility for millions of couples worldwide.

NAC has been found to improve fertility in both men and women by increasing sperm count, motility, and morphology in men, and improving ovulation and increasing pregnancy chances in women undergoing fertility treatments.

A study found that NAC supplementation improved ovulation in women with PCOS, a hormonal disorder which affects up to 20% of women of reproductive age, causing irregular periods, infertility, and other symptoms.

NAC for heavy bleeding & fibroids 

Menorrhagia, or heavy menstrual bleeding, is a common hormonal woe. Your liver’s detoxification process can be disrupted by a lack of proper micronutrients, causing an excess of estrogen to circulate in your system. NAC has been shown to support the liver’s detoxification and reduce the size of uterine fibroids, which can lead to menorrhagia.


In conclusion, N-Acetyl Cysteine (NAC) is a powerful antioxidant and amino acid that has been shown to improve fertility and symptoms of PCOS. NAC has been found to reduce oxidative stress, improve insulin sensitivity, increase sperm count and motility, and improve ovulation. Further research is needed to confirm the full effects of NAC on fertility and PCOS, but the available evidence suggests it has potential as a promising treatment option.
