Insomnia is a disorder that has been observed in different patients. It is characterized by recurrent difficulties with sleep initiation, maintenance, duration or quality despite adequate opportunity and time for sleep. Insomnia not only affects an individual's mental health but also creates social stress and lower productivity. Sedatives are among the most common drugs prescribed for treatment of insomnia. However, these are associated with many side effects such as daytime drowsiness, dependence and addiction making patients reluctant to self-medicate.

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.
