I read a lot about Maca last year so I decided to take it. I ordered it online - tried to look for the company's name but I could not find it, sorry. However I mentioned to my acupunturist that I was taking it and she told me to stop taking it as there have really not been any conclusive studies that it helps with egg quality/production. She gave me a transcript of an interview about it and essentially the message was that it is inconclusive as to whether it helps or hurts IF so better to avoid it & there are no established guidlines as how much to take. For what it's worth, I had no side effects while taking it ( I took powder form in smoothies) but I had a horrible cycle as far as egg production & quality when I was using Maca. Not blaming it on Maca but I always analyze the outcome of a cycle and what I may have done differently. Just my two cents. Good luck whatever you chose to do!
