Willow, the benefits are greatest pre conception and in the first trimester... This is due to the fact that prior to conception the folate helps build a healthy ovum. After conception it helps ensure healthy embryonic/fetal development. I personally think it doesn't hurt and it can help you. Have a little google on benefits of folate and you will see what I mean. Having said that. If you are on Elevit you are getting 800mcgs a day... So, perhaps it's not so important.

Like you for the same reasons I am on 5mgs of folate daily. I will continue it, just because I believe it's beneficial. To get the best benefit of folate it's important to take b12 and b6 with it as well.
