Cortisol (12-2am), Melatonin (12-2am)
The Sleep Profile is a non-invasive saliva test that assesses two major causes for insomnia: imbalances in melatonin and cortisol.  Melatonin is a peptide hormone produced by the pineal gland which helps to control normal sleep patterns. Deficiencies of this hormone can lead to insomnia; however melatonin supplementation can effectively treat this problem if diagnosed correctly.  Imbalances in the diurnal pattern of the glucocorticoid hormone cortisol can also lead to sleep disturbances.
