1 Snooze Foods and Pick-Me-Ups Certain foods contain an amino acid called tryptophan that causes sleepiness. 2  Carbohydrates make tryptophan more available to the brain, which is why carbohydrate-heavy meals can make you drowsy. It is made in the brain by converting tryptophan first to serotonin and then to melatonin, which is secreted at night by the pineal gland in the brain to induce and maintain sleep. 2  Scientific evidence shows little or no benefit of melatonin in improving sleep.
Works with the body's natural cycle to safely and gently promote sleep. All of us produce the hormone melatonin naturally in our brains. It helps set sleep and wake cycles in humans, animals, and even plants and fungi. The amount of melatonin your body produces varies throughout the day and is based on its exposure to light. Darkness makes the body produce more melatonin, which induces sleep, while light suppresses its production. We include melatonin in a handful of our products to help gently promote sleep.
