This article reviews the latest insights from ZRT Laboratory doctors on hormone testing, sleep biology, stress physiology and the importance of maintaining healthy daily hormone rhythms for long-term wellness.

Most people think of melatonin as a sleep supplement — but this remarkable hormone is produced throughout the body and plays a central role in immune defence, inflammation, pain management, gut health and even cancer protection. Dr. Allison Smith dives deep into the biochemistry of melatonin and explains why getting your levels right matters far beyond a good night’s sleep.

Melatonin is far more than a sleep supplement — it is a master regulator of the body’s circadian rhythm, a potent antioxidant, and a key signal for cell repair and gene transcription. Understanding how melatonin is produced, what its daily curve looks like, and how it can be accurately measured through first-morning urinary MT6s testing is essential for anyone investigating sleep disturbances, fatigue or hormonal imbalance.
