Melatonin Profile


Melatonin is a hormone that also acts as a neurotransmitter. It is synthesised in the pineal gland in our brain and is converted from serotonin, also known as the hormone of happiness.

However when we are stressed or overworked we exhibit high levels of cortisol – our stress hormone – which in turn lowers our levels of melatonin. This is why many people nowadays have trouble sleeping.

This test can indicate how your melatonin levels change throughout the day and whether there is a problem with the production of this vital hormone.

This package includes :

  • A test kit for self collection
  • Laboratory report 


Many people are familiar with melatonin because of its influence on sleep. Healthy melatonin levels positively influence the initiation and maintenance of quality sleep cycles. In contrast, disruptions in melatonin curves may clinically present as disordered sleep patterns.

Although it’s most well-known for its association with sleep, melatonin holds many other clinically relevant roles. It is a potent antioxidant found in almost every cell in the body! It stimulates the immune function and decreased levels are often connected with cancer and diseases of the central nervous system.

Melatonin may also aid in weight loss and mood support, and has been shown to exhibit anti-ageing potential. In addition, studies have shown that its antioxidant activity may be protective to the ovaries, improving ovulation cycles.

This is why testing your melatonin curve patterns can help indicate not only why you may have trouble sleeping, but also give more information about what other issues may arise if the levels are low.
