I recently bought Maca Powder from one of the supermarkets as I have been suffering from Polycystic Ovary Syndrome since I was 15 years old. I am 22 years old now, and I hadn't had a natural period in over 5 years. I have been trying every remedy that has been researched for reliving PCOS. Apple cider vinegar being one of them, yet that seems to have no real impact.
However, I used maca powder in my smoothies for 2 weeks. And voila!. my first period! I haven't been so delighted! It may taste absolutely foul and smell revolting, but it seems to be the miracle for me. I have it in my smoothies every morning.
Try it and see what the benefits are for you. Many say it does nothing for them, but you may well be the lucky one.
Good luck :)
