I have a very sensitive stomach when it comes to taking vitamins. Taking the full dose (3) doesn't upset my stomach, even during all the morning sickness! Highly recommend this. Not to mention this site is the cheapest I found for these. GNC wanted 30 something for just a month supply.
In the past, I've had sensitivity to most multivitamins -- which is why I quit taking them. But, when I informed my primary doctor that we are planning to expand the family, she encouraged me to get on prenatals. This is the first brand I tried and I LOVED them! I felt a small boost of energy, PLUS, no icky stomach feelings because of the RAW natural component. I completely encourage that if you are trying to get pregnant, that these are a great pick!
I really couldn't take vitamins during my pregnancy because I was so sick. I did take the Perfect Prenatal when I could because I could take them on an empty stomach without any problem. Now that I am nursing I can really tell a different about how I feel. Within a day of not taking them, I can tell I have less energy and just not feeling too well all together.
