I decided to purchase the NAC- N-Acetyl Cysteine and Super Magnesium from the PCOS Diva Store. I chose to do business with Amy because I also have PCOS, and I really value the research and information she posts. It’s only been a couple of months of using the products but so far so good. I go to the doctor next month and am really anxious to see how my labs look. I’m feeling much better already. Thanks Amy for all you do for women!
