The other important piece of the puzzle is personalization, which is where DHA testing plays a very important role in optimizing intake. If someone has a DHA level less than 5%, then we would recommend they take more than someone who is above 5%. So, for example, if you are below 3%, then we would recommend 900 mg DHA per day throughout pregnancy. If you are between 3-5% (which many women are), then we would recommend 600 mg DHA per day. If you are above 5%, then it makes senses to maintain an intake of 200 mg DHA per day. These recommendations are well within doses that have been studied and shown to be safe for mom and baby. If you make any changes, make sure to re-test your Prenatal DHA level in 2-3 months to see how it has improved.
