The general recommendation for DHA during pregnancy is 200 mg per day on top of your current diet, which some estimate delivers about 100 mg DHA per day – for a total of 300 mg per day. While the American Academy Obstetricians & Gynecologists does not have an official recommendation, organizations like the March of dimes support the 200 mg a day recommendation, along with many other medical and scientific bodies across the world. Whether or not 200 mg a day is enough is the big question. For us at OmegaQuant, it comes down to the blood level. One side of the equation is that most women are not getting to 100 mg per day, much less getting 200 or 300 mg per day during pregnancy. According to the latest research, most women of childbearing age are getting about 60 mg of DHA a day and less than 1 in 10 takes an omega-3 supplement. In that case, we would not expect their level to be above 5%. So if most women are not meeting even the bare minimum recommendations, it is hard to know whether or not we need to increase the recommendation to 600 mg a day vs. making sure women get to the 200 mg recommendation.
