N-Acetyl Cysteine May Prevent Miscarriage

A number of studies have demonstrated how women with recurrent loss may have higher levels of oxidative stress, and N-Acetyl cysteine - a powerful antioxidant - may be able to help. Oxidative stress can trigger a cascade of events which may cause a pregnancy to fail and N-Acetyl cysteine may arrest this process allowing pregnancy to proceed. An Egyptian study (1) concluded that:

"NAC (N-acetyl cysteine) is a well-tolerated drug that could be a potentially effective treatment in patients with unexplained RPL (recurrent miscarriage)."

This study gave eighty women with a history of recurrent pregnancy loss 600 mg of N-Acetyl cysteine per day which upped the chances of staying pregnant past 20 weeks by and astonishing 290%. The women also took 500 mcg of folic acid and were compared to a control group of eighty six women who took only the same amount of folic acid.

N-Acetyl cysteine is a powerful antioxidant that can boost the body's levels of a super-antioxidant called glutathione. Interestingly, a Polish study (2) has shown that glutathione may be low in women with recurrent loss:

"The decreased activities of the antioxidant enzymes, red cell and plasma glutathione peroxidase, may play an important role in the aetrology of miscarriage."

This study examined the glutathione levels of forty women who had experienced miscarriages in their first and second trimesters and compared their glutathione levels to thirty six similarly matched healthy women with viable pregnancies. The results of this study demonstrated that red blood cell and plasma glutathione levels were lower in women with miscarriage.

N-Acetyl cysteine may be a safe and effective way to reduce your chances of miscarriage by decreasing oxidative stress and acting as a precursor to glutathione. The amount used in the studies - 600 mg - is generally regarded as being safe and has been used in other studies successfully especially in women with PCOS. You should always ask your physician before embarking upon a new nutritional supplement regime, especially if you are pregnant.
