Why pregnant and nursing women need DHA


The Omega-3 fatty acid DHA is critical for developing babies, but many people don’t realize it’s also beneficial for pregnant and nursing women.* This essential fat appears to play a role in helping women feel good emotionally, both before and after giving birth.*

Sadly, 75 percent of pregnant women don’t get enough DHA. [i] That’s a problem because pregnancy depletes DHA stores, and levels continue to decline after delivery. Why? Blame nature. When expecting moms and developing babies both need a nutrient, nature always favors the baby. And that means mamas may suffer the consequences.

Here are two research-backed reasons why pregnant and nursing women need DHA:

  • Positive outlook: It’s not uncommon for women to feel down after giving birth, or even while pregnant. Interestingly, women who have low levels of DHA are more likely to experience the baby blues.* [ii] While not all studies agree, some have shown that giving women Omega-3 supplements during pregnancy supports feelings of positivity — both before [iii],[iv] and after giving birth.*[v],[vi]
  • Peace and relaxation: As much as you may want and love your new child, being pregnant is still a stressful experience. Your body is changing, your hormones are raging and everything in your world is about to turn upside (either for the first time or again). Fortunately, a recent study found that women who have a high intake of Omega-3 fatty acids are more likely to stay peaceful and relaxed while pregnant than those who consume little to none.*[vii]

How much is enough?

Most studies typically use between 1,000 – 3,000 mg of a combination of EPA/DHA per day to support emotional well-being before and during pregnancy*; however, far less may be needed. A recently published study on the use of DHA in preventing the baby blues used just 300 mg per day.* [viii]

Fish oil is the most concentrated source of EPA and DHA. However, if you’re vegetarian, you can substitute flax oil instead. It contains the Omega-3 fatty acid ALA, which is partially converted to DHA in the body. According to a 2002 study published in the British Journal of Nutrition, pregnant women convert up to 9 percent of ALA to DHA, so you can still get a good dose of the stuff without consuming fish. [xi] For example, one tablespoon of Barlean’s Fresh Flax Oil Organic provides 7,640 mg of ALA. Assuming a 9 percent conversion rate, that tablespoon provides nearly 690 mg of DHA.
