Hi Lily,
I take loads of vitamins, fish oils etc. I have done right from the beginning. I discussed this with my chemist before I started. He said he was unsure of whether it would affect my losses but to keep taking them and see how it goes. It never affected my losses one bit.
I'm not saying it's ok to take them! I was told by a few people not to take them.
Saying all that it has not stopped me from losing my hair! I'm like Hansel and Gretel, leaving a trail of hair everywhere I go!
