The following is a questionnaire that will estimate your daily omega-3 DHA intake. DHA is an omega-3 fatty acid mainly found in seafood, eggs and dietary supplements. Please answer the questions based upon your consumption of the following foods over the past 2 months. You will be shown a sliding scale bar to provide amounts. Answer each question as best you can and feel free to estimate if you are not sure, as a guess is better than leaving the answer blank.

TOTAL DAILY DHA INTAKE:
Thank you for taking the survey. Your daily DHA intake is below expert recommendations for pregnant women.1 DHA is found in seafood, eggs, and dietary supplements (algal or fish oil). If you are pregnant, consider talking to your healthcare professional about a DHA supplement in addition to your prenatal vitamin. Experts recommend that pregnant women with low DHA intake or status consume 600-1000mg of omega-3 per day (as DHA or DHA plus EPA).1
Thank you for taking the survey. Experts recommend pregnant women consume at least 350-450mg of omega-3 per day (as DHA alone or DHA+EPA with at least 100-200mg as DHA).1 If you are pregnant, consider talking to your healthcare professional about a DHA supplement in addition to your prenatal vitamin to optimize your DHA intake.
This 7-question food frequency questionnaire was developed by DSM Nutritional Products and adapted by Dr. Susan Carlson and her team of Nutrition Scientists at the University of Kansas. The questionnaire has been validated in pregnant women residing in the Midwest United States and is currently used as a screening tool early in pregnancy at the University of Kansas Medical Center to identify pregnant women at high risk of preterm birth due to low DHA intake.1,2
