  • Cortisol (12-2am)

This Cortisol and Melatonin analysis is a non-invasive saliva test that assesses two major causes for insomnia:

  • Imbalances in melatonin
  • Imbalances in cortisol


Melatonin is a hormone produced by the pineal gland which helps to control normal sleep patterns. Deficiencies of this hormone can lead to sleep issues, both falling alseep and staying alseep.

However melatonin supplementation can effectively treat this problem if diagnosed correctly.


Imbalances of the hormone cortisol can also lead to sleep issues.

Cortisol and Melatonin work together in your circadian rhythms (your natural sleep cycle).


Insomnia is defined as a repeated difficulty with:

  1. Falling asleep
  2. Staying asleep
  3. Amount of hours that you sleep
  4. Quality of sleep


Mild (transient or short-term) insomnia is known to affect between 30-50% of the general population, whilst chronic insomnia has a prevalence of 9-15%.


This disorder affects energy levels, memory, concentration and problem solving skills. In addition, it has been linked to learning disabilities in children. Sleeplessness not only affects the individual but also produces social stress, lowered employee productivity and higher number of accidents. Therefore it is vital that the cause and treatment of your insomnia is addressed.
