No, NASA has not discovered milk on the moon. Instead, moon milk is a trendy new insomnia-fighting drink for adults. There really isn’t anything special about moon milk.
To put it simply, moon milk is regular milk served warm with natural flavorings such as honey or fruit added. So how is it beneficial to sleep? Milk contains the amino acid tryptophan, which can help you relax and feel sleepy. That makes it a natural sleep aid that also supplies protein and other essential nutrients. The warmness of it raises our internal temperature, causing us to feel calm and relaxed as well.
