I have read of maca helping balance hormones in PCOS, I never took it though because I was scared of it raising androgen levels which is already high in PCOS. two supplements that are recommended also for PCOS : Myo-Inositol ,and Nac N-Acetyl Cysteine
In a study published in 2007 in Gynecological Endocrinology, 25 women received MYO (4g/day) for six months. The results: 88% of patients had one spontaneous menstrual cycle during treatment, of whom 72% maintained normal ovulatory activity. A total of 10 pregnancies (40% of patients) were obtained.
Raffone et al compared the effects of metformin and MYO in women with PCOS. Sixty women received 1,500 mg/day of metformin, while 60 women received 4 g/day of MYO plus 400 mcg of folic acid. Ovulation was restored in 65% of women treated with MYO vs. 50% in the metformin group. More pregnancies occurred in the MYO group vs. metformin (18% vs. 11%).
A study published in the European Review Medical Pharmacology examined the effects of both forms of inositol in women with PCOS undergoing fertility treatments. One group received 2g of MYO twice daily and a second group with .6g of DCI twice daily. Women who received MYO had better, more mature eggs and more pregnancies than those who took DCI.
N-Acetyl Cysteine (NAC), helps women with PCOS improve fertility, reduce inflammation and oxidative stress, and improve metabolic complications of PCOS including insulin resistance, fatty liver, and high cholesterol. NAC also increased the take home baby rate in women with recurrent pregnancy loss.
