They’re packed with potassium and magnesium – nutrients that double as natural muscle relaxants. Plus, they contain the sleep-inducing amino acid tryptophan, which ultimately turns into serotonin and melatonin in the brain. Serotonin is a neurotransmitter that promotes relaxation; melatonin is a hormone that promotes sleepiness. It takes about an hour for tryptophan to reach the brain, so plan your snack accordingly.
