Why not talk to your own GP?
One of the vitamins you can take are the B group vitamins, these help with red cell production, vitamin b 6 is good for PMS (my doc prescribes me a large dose of this even though I've had a hysterectomy), B complex vitamins are good for energy levels too.
I'm prescribed Pregaday for Iron and Folic acid as I'm deficient in these.
I also take vitamin D and Calcium combined ( but not the same time as iron as calcium inhibits absorption).
Do take a vitamin c supplement, Tesco do a lovely effervescent raspberry one that tastes much better than the chewable orange flavoured ones. And excess Vitamin c is eliminated jn urine.
Be careful of vitamin a, iron, and other heavy metals such as zinc, as too much is toxic.
