Supplements

I’ve heard people say that supplements are key to improving egg quality etc. My partner is leaving for work soon & we probably won’t see each other for another 3 months, but again, I’ve heard this is how long it takes for things to take effect, so thought now is a good time to start. What should I be taking??

Also, I live in Cyprus so cant get lots of things here so any idea where I can source them online would be helpful.
