Melatonin is a chemical in your body that is responsible for regulating your sleep cycle. Your pineal gland is responsible for producing that melatonin. Each night your body produces approximately 25mcg of melatonin to promote a peaceful and restful sleep.

The hormone cortisol is produced in the adrenal glands and is primarily responsible for regulating blood sugar, helping to metabolize fats, protein and carbohydrates, and assisting in managing our stress response. We all have times of stress in our lives, and cortisol helps us to function during these times.
