Softgel + tablet prenatal, 1 of each daily. Provides 1,330mcg DFE folate as folic acid (800mcg folic acid, not methylated), 110mg choline, 200mg DHA from fish oil, 27mg iron as carbonyl iron, and 600 IU vitamin D. Contains fish (anchovy, sardine, tuna) and soy, and uses a gelatin softgel, so it is not vegan or vegetarian. Widely available at drugstore and grocery retail; Amazon lists the 30-day pack, so it is worth price-checking in store. No independent third-party testing certification found on label/brand materials at time of review.
