Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — sleep hormone 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.

Chronic stress silently disrupts adrenal function, leading to fatigue, brain fog, low mood, and hormonal imbalance. Cortisol — the body's primary stress hormone — follows a precise daily rhythm, and when that rhythm breaks down, the effects ripple through every system in the body. Saliva and blood spot cortisol testing offer a non-invasive, clinically validated way to assess adrenal health, capture the Cortisol Awakening Response, and identify patterns that standard blood tests often miss. This guide explains how cortisol testing works, what your results mean, and which at-home test is right for you.

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.
