Women/Age/Iron Micros Question...

Hi, I'm new to MFP and wondering, if, as a 50 year old woman, my "Iron Micros" (which just says 100%, not mgs) is set for an 18mg requirement (pre-menopausal) or 8mg requirement (post-menopausal) woman?

Is anyone familiar with this default setting? And if I need to go in and change the iron requirement to reflect my situation, how can I do that?
Thanks for any help!
