Could the superfood known as blueberries be any more super? If you’re a new mom, the answer is: maybe.

A new study by researchers in Toronto finds that a dietary supplement regimen of powerful antioxidants blueberry juice and blueberry extract can help ward off the “baby blues.”

The temporary mood swings and sadness experienced by many new moms can sometimes lead to more serious postpartum depression.

In this study of 41 pregnant women in their late 20s and early 30s, women given the blueberry supplements for three days suffered no drop in mood on the fifth day after giving birth, when the so-called “baby blues” are said to peak.

The women were also given amino acids tryptophan and tyrosine to counteract the loss of so-called feel-good hormones in a woman’s brain after she gives birth.

The 20 mothers who did not take the supplements tested higher for depression after their babies were born.

The study was published recently in the journal Proceedings of the National Academy of Sciences.
