Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — melatonin saliva test

Saliva hormone testing is a non-invasive, scientifically validated method for measuring the bioavailable fraction of key hormones — including cortisol, oestrogen, progesterone, testosterone, and DHEA — from the comfort of home. Unlike standard blood tests, which measure total hormone levels including the inactive, protein-bound fraction, saliva testing reflects the hormones that are actually active in tissues and driving biological effects. Combined with LCMS (liquid chromatography tandem mass spectrometry) technology, saliva testing offers exceptional accuracy, sensitivity, and clinical relevance for assessing hormone balance, monitoring hormone therapy, and understanding the root causes of symptoms such as fatigue, mood changes, poor sleep, and hormonal imbalance.

Learn the science of saliva testing, how it measures bioavailable hormones, and why it’s trusted by patients, clinicians, and wellness experts.

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.
