L.B.
I have been a vegetarian (lacto ovo) for more than 20 years. I had healthy pregancies with both of my daughters (9 lbs 12 oz and 7 lbs 10oz at birth). I took a vegetarian pre-natal vitamin since I did not want the gelatin contained in the prescribed kind. I had no problems, and my doctor was not concerned at all. She never mentioned anything about zinc levels. I hope that helps!
