From Needed's website: "8 capsules allows our Prenatal Multi to deliver all of the vitamins, minerals, and botanicals needed for complete, comprehensive nourishment — many of the best nutrients are bulky and can’t fit into 1- or 2-a-day prenatal capsules. You’ll see that a number of nutrient dosages are quite unique including 400mg of Choline and 200mg of Magnesium. With our capsules, it is easy to divide the full dose among meals throughout the day."
