I wanted to recommend Rainbow Light prenatal vitamins.
Not only are they great vitamins (and readily absorbed by the body since they are whole food) but they really help with nausea. They have an herbal complex in them with ginger to help with nausea.
They have a one a day and a six a day one. I know six a day seems like a lot, but I took 2 with each meal and prefer it because I get that ginger boost 3 times a day and I think its probably more useable to the body to get doses throughout the day. I found with Milena, I got nauseous in the afternoon, and when I took the vitamin it went away.
I don't work for the company, I promise!

I just know that my best friend worked at Whole Foods and they really recommend that brand of vitamins. I like their protein powder too.
