Night milk: milk taken from cows at night might be the sleep aid you need

Sedative effects of night milk have not been tested on people but the high amounts of tryptophan and melatonin suggest it may be healthier than Ambien

As anyone who has suffered from insomnia knows well, drinking a glass of warm milk doesn't always help. But it might, a new study reports, if the milk is taken from a cow at night.

According to an animal study in the Journal of Medicinal Food, night milk - literally milk collected from a cow at night - contains high amounts of tryptophan and melatonin, supplements proven to aid sleep and reduce anxiety.
