Based on my experience with aromatase inhibitors (letrozole, exemestane) I know exactly what if feels like when my estrogen gets too low and my libido completely tanks. The opposite sex, or rather sex in general, just doesn't concern me. It's like thinking about a slice a bread or something! This is where the vitamin A comes in. It's amazing for my dandruff, and one of the clearest signs my body gives me is when I get dandruff on my eyebrows. About 20,000 IU's daily takes care of this and I have great energy and a humming metabolic rate. The kicker? My libido disappears! I take it along with D3 and K2, and a few days in and it's gone. I get off it, my libido comes back with a vengeance as well as the dandruff. Anyone have any ideas on what I can do to remedy this? I think it's the vit A because I know it's anti-estrogenic and the feeling is identical to aromatase inhibitors. I just want to have a libido and be dandruff free simultaneously!
