                                According to scientific evidence, milk contains the amino acid tryptophan, which the body uses to produce sleep-regulating hormones like melatonin. This fact is central to the age-old question: what is the best time to drink milk, day or night? The ideal time often depends on your specific health goals and how your body responds.
