DHA Dosage

Although no DHA dosing guidelines have been established for pregnant or breastfeeding women, some sources have recommended 300 mg daily, either through dietary sources or through supplementation. There are currently no established DHA dosage recommendations for the treatment of high triglycerides or the prevention and treatment of heart disease.

An Introduction to DHA Dosage

The recommended DHA (docosahexaenoic acid) dose has not been clearly established. For many uses (particularly cardiovascular uses), recommendations suggest a dose of DHA plus EPA (eicosapentaenoic acid), not just a dose of DHA alone. EPA is a similar (but different) omega-3 fatty acid, and it cannot be assumed that taking DHA without the EPA will provide the same health benefits.

DHA Dosing for Pregnancy and Breastfeeding

A recommended intake of DHA for pregnant and breastfeeding women has not been established. Some sources have recommended 300 mg a day, either through dietary sources or through supplementation. One DHA supplement designed especially for pregnant and breastfeeding women (Expecta® Lipil®) provides 200 mg of DHA per day.

DHA Dosing for Formula-Fed Infants

Many infant formulas now contain DHA. If you would like to ensure that your baby gets enough DHA, you may want to use one of these formulas (it is probably not a good idea to use a DHA supplement instead). These formulas contain varying amounts of DHA. The recommended intake of DHA for infants has not been established.

DHA Dosing for High Triglycerides

The American Heart Association (AHA) recommends that people with high triglycerides take a supplement with 2 to 4 grams (2000 to 4000 mg) of EPA and DHA daily. The AHA does not provide a recommendation for DHA only, probably because there is more evidence that the combination is effective for triglycerides (opposed to DHA alone).
One study used 4 grams of DHA alone to successfully treat high triglycerides, but more research is necessary before this dose can be recommended.
