Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — melatonin and DNA protection

Melatonin is far more than a sleep hormone. As a potent antioxidant, anti-inflammatory agent, and immune modulator, melatonin plays a critical role in protecting against oxidative stress, suppressing harmful inflammatory pathways, and supporting the body’s defence against viral infection. Melatonin production declines progressively with age — a pattern that mirrors the increased vulnerability to severe illness seen in older adults. This article explores the science behind melatonin’s immune and anti-inflammatory functions, the relationship between melatonin decline and age-related disease risk, how to support melatonin production naturally, and how at-home testing can confirm whether your melatonin levels are adequate.

A melanoma diagnosis changes everything — but it can also be the catalyst for a smarter, more proactive approach to skin health. In this personal account, Lissa Gienty of ZRT Laboratory shares her melanoma story and the evidence-based steps she now takes to protect herself, including optimising vitamin D and melatonin levels and monitoring her diurnal hormone rhythms.

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.
