What does Melatonin do to your body?

So, we know that melatonin works directly with your body’s circadian rhythm or biological clock, having a huge impact on your internal system. Melatonin binds to receptors in your body to help you relax and get tired for bed. By taking melatonin your body is directly affected as your circadian rhythm starts to change and coincide with when you take the supplement. It is important that your body can prepare itself at night to get ready to rest. Achieving a restful sleep has a tremendous impact on all areas of health and well-being.

Melatonin is produced in the pineal gland at night and serves as a time to cue your biological clock to anticipate sleep in the brain. Melantonin also aids in antioxidant defenses and helps to regulate blood pressure, body temperature, cortisol levels and sexual and immune functions.
