About pretnatals... my normal vitamin (which I love and have taken for over a decade now) is EveryWoman's One a day by New Chapter Organics. (highly recommended as they are a whole food vitamin that can be taken on an empty stomach
New Chapter | Natural Vitamins, Herbals, Supplements, Fish Oils and Calcium). So I bought the prenatal vitamin and it's three tiny pills a day with ginger and various herbs to help ease the stomach.
However I was exhausted after being awake for 3-5 hours every day (first 3-9 weeks of pregnancy), and when some good friends got me a new brand for Christmas I tried that and it turned out to give me a lot more energy (up to 6-9 hours a day as long as I eat meals on time). That complex had the Vitamin B set (which enables your blood cells to hold more nutrients and oxygen and work more efficiently but may make you a bit more thirsty). So I think if I were to take the first prenatal again with a B complex the energy issue would be better solved, but I can happily recommend both. The first had such good ingredients (and more importantly, bio-available forms of those ingredients that my primary care physician and her assistants were all taking pictures of the bottle when we brought it in).
So, maybe compare ingredients or try more than one and see how you feel afterwards?
The second vitamin is Rainbow LIght Prenatal One, and I do have to have some food with it in the morning but not a lot. Also it looks like they have different prenatals for each trimester now, which sounds amazing though i haven't compared ingredients yet. (
Rainbow Light - Healthy Multivitamins & Nutritional supplements). That is also Non-GMO and excellent forms of the vitamins.
Also for those whose boobs are hurting (and isn't that all of us from time to time?) That's your body needing iodine because of the growth of the boobs etc (it's essential for your thyroid health as well) and many environmental chemicals around us now compete with it in your body so something like bromine, chlorine or flouride displaces it in your system. But basically even if you aren't prgenant and your boobs hurt your body is lacking in iodine.
