I really like these prenatal vitamins. They are recommended time and time again. They are food based, which are the kind of vitamins that are most recommended. I purchased the regular 1/day Rainbow lights and they were just too big for me to swallow. These vitamins are exactly the same but instead of 1 you take 3 mini ones! This is working so much better for me. Three of these contain exactly the same vitamins and minerals as 1 of the regular size Rainbow light prenatal vitamins. I usually try to take 2 in the morning and 1 before bed, this way I'm spreading the release of the vitamins and minerals out too.
