N-3 PUFAs is a kind of essential fatty acid,however the formation is too slow. Studies show that intakes of N-3 PUFAs is associated with MDD.It have to be got from food like deep-sea fishes. EPA and DHA are crucial for the body.Although studies have shown that reduced N-3 PUFAs were correlated with MDD, and patients with an elevated rate of N-6 PUFAs /N-3 PUFAs or a low level of DHA may be at higher odds for suicide. Trials on whether N-3 PUFAs is effective in the treatment of MDD is still controversial, which might be affected by several factors, such as dose, duration etc.. Now there is no large-scale randomized controlled clinical trial in determining the effects of N-3 PUFAs add-on in treatment of MDD.
Placebo Comparator: control group
the control group will be given 4 soybean oil capsules ( placebo capsule,1g/one capsule) twice daily after two meals at roughly the same time each day,lasting for the first 6 months.placebo capsule will be provided by the Hunan Kangqi100 Biological Technology Co.Ltd.The placebo capsule's appearance and flavor are made the exactly the same as the fish oil capsules .
