Basic Prenatal is a comprehensive supplement formulated with the special needs of pregnancy in mind. Manufactured with none of the additives and coatings usually found in mainstream prenatal tablets, Basic Prenatal includes only the most bioavailable nutrients.
High-potency multiple vitamins may sometimes be difficult for a woman to "stomach," particularly during the first trimester of pregnancy. Therefore, Thorne does not include large amounts of the nutrients commonly known to cause stomach upset. Instead, these nutrients are included in their most active or absorbable forms for superior utilization. Among these are the active forms of several of the B vitamins – pyridoxal 5'-phosphate (vitamin B6), riboflavin 5'-phosphate (vitamin B2), folinic acid and L-5-MTHF (active forms of folate), and adenosylcobalamin and methylcobalamin (vitamin B12).
