Well, I could be wrong here, but gonna give this a shot!
Prenatal vitamin and baby aspirin are fine to take with anything.
Vitex- does MILDLY inhibit the release of FSH- but only slightly. Vitex increases the LH production. Which causes a shift in your estrogen/progesterone favoring progesterone.I remember reading somewhere that B6, Dong Qui (sp) or evening primrose oil actually works better in the long run. However, the one benefit that Vitex has is regulating your menstral cycle. Vitex takes a while to actually work-like 5 months I believe, and I personally stopped using it when I got pg because I read that it wasn't safe.
Maca- (I've never taken this but plan to after I give birth). As far as I remember in my readings maca is not considered an herb but instead a supplement. Kinda like eating a carrot and the benefits that it would give to you. As far as I know Maca also increases LH production so taking this + Vitex is probably overkill.
DHEA- is a steroid that is naturally produced by your body and helps to regulate hormones. It also helps our brain, and reverses the aging process. Technically before taking DHEA we probably *should* have our levels tested to see if we actually need to take it and I don't believe taking it long term is a good idea. I took mine on my own, but only for 2 months. Honestly, I have no idea how this would interact with the other supplements, but it seems like they effect different things-I took it with Vitex.
Royal jelly-I had to do some research on this! "Yes, royal jelly and other honey products can be taken with fertility drugs. Royal jelly contains a compound of various vitamins and nutrients that are recommended for fertility (including A, C, E, B complex, and amino acids.) It does not contain actual hormones, although some researchers believe it may help regulate hormones. Taking honey-derived products would be comparable to taking any other multivitamin supplement. They help to make an ideal environment for conception. Royal jelly would be recommended for female fertility." Apparently just a vitamin!
Flaxseed oil- Ive never heard of someone taking this all the time. Most of the women I came across used Evening primrose oil up to O then flaxseed after to menses. Flaxseed is supposed to help balance estrogen/progesterone so it is kinda redundant to take this with Maca or Vitex. My OB told me that EPO and Flaxseed have no benefits-but I don't buy everything doctors tell me!
I am not a naturopath or an herbalist, but I will do my best to explain based on my own research.
I don't think anyone can tell you what you should be taking.
Thanks Mattie I'll try to do some more research before jumping into using these things. I was just so excited to have found a group like you guys who are also in the same boat, over 40 and TTC. But I guess I just got into a "more is better" way of thinking.
Oh I know the feeling.
