I take the Garden of Life Prenatal, called Raw Code and one dose is 3 capsules. People can't absorb all of one a day multivitamin, so I prefer having 3 caps, and these I can take even if I'm nauseated.
The D3 is one capsule of 10,000IU. My lab result is only 43, and it should be 60nm/ml. With that I take additional iron, and my lab was perfect. I also take algae based DHA for the baby's brain and eat foods with flax or add flax oil to meals.
My OB is very pleased with our health.
