Rainshiny, DHEA is controversial, I would not take it before 40 and definitely under doctors' supervision. It's a hormone and can seriously mess up your hormonal balance in certain cases. check your DHEA levels first, it's a simple blood test to make sure you are low on DHEA before considering taking it. also read up on the side effects which can be quite dramatic like serious hair loss, I have seen this happen to our B&B ladies.
re royal jelly, it's not proven. I have taken fresh royal jelly in the past but it did not do anything. most recently I read a book on egg quality and royal jelly was mentioned as the one to avoid. I know everywhere you read on line they praise royal jelly but there have not been any studies to prove it does anything at all so i ditched it a while ago
raspberry tea leaf is great in the first half of your cycle together with red clover and nettles. I've been drinking it for years. Cant say I noticed much improvement but somehow I think it's a good substitute for caffeinated tea/green tea. I also drink mate tea which is unlike green tea, alkaline so it helps our bodies deal with all the acidity
chasteberry extract is again controversial, it seems to work well for some, particularly when ladies have problems ovulating naturally but if your cycle is OK it may mess it up
