It is reported a research that publishes on October of this year " magazine of American medical association " reveals, a random experiment including more than 2000 women finds, take the decline of the depression level of postpartum that DHA additive will not cause mother, or make their child's early cognition and language development in childhood improved.
Test of this investigation is for 2399 women of maternity hospital of Australia to launch. While registering in 2005 and 2008 and participating in the test, at least pregnant 21 weeks for the person. A group receives fish-oil capsule (offer 800 milligrams of DHA every day) rich in DHA . Its control group receives the equal amount of vegetable oil capsule not including DHA.
Discover, 6 months after producing, every group of woman's highly depressed symptom incidence does not have obvious difference: There are 9.67% that have illness coming on in the women who take DHA additive, there are 11.19% in the women who take placebo. In two groups, it was more general that the women diagnosed as depression in the past or now suffered from postpartum depression. The difference that two groups of infant and pre-school children's average cognition or language scores synthetically is not obvious. Among them the bad reaction appears, including the phenomenon of serious bad reaction is pretty much the same. This test has queried to take the benefit of DHA additive in pregnancy period.

The conclusion that the researcher must appear finally is: The test result does not support the pregnant woman to take DHA additive at ordinary times.
