GreenFood Nutrition Melatonin 120 capsules

Melatonin is a natural hormone found in the body that plays a key role in regulating the sleep cycle. It is produced by the pineal gland, a small gland located in the brain. Melatonin is known as the "hormone of darkness" because its production increases at night and decreases during the day. This hormone helps signal the body when it's time to go to sleep and when to wake up. Melatonin acts on specific receptors in the brain that help regulate the sleep-wake cycle. Melatonin production is controlled by the body's internal biological clock, known as the circadian rhythm, which responds to changes in light and darkness in the environment. When it gets dark, the pineal gland starts to produce more melatonin, which signals the body that it's time to go to sleep. During the day, when there is light, melatonin production decreases, which helps the body stay awake. Although the body produces melatonin naturally, this hormone can also be found in small amounts in some foods. Among the foods, that contain melatonin, include fruits and vegetables (cherries, tomatoes, grapes and broccoli), walnuts, almonds, oat, rice and milk, which also contains a small amount of melatonin. Melatonin is also available in the form of dietary supplements, which are widely used for a variety of purposes and provide precise dosage.
