Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — Cognitive Function

Struggling with fatigue, stress, or mood changes? Saliva hormone and neurotransmitter testing helps identify underlying imbalances with accurate results and clear insights to support better health and wellbeing.

Neurotransmitters are chemical messengers in the brain that play a crucial role in regulating our mood, emotions, behaviour, and overall mental health. Imbalances in neurotransmitters have been linked to a range of psychiatric and neurological disorders, including depression, anxiety, ADHD, Parkinson's disease, and Alzheimer's disease. A neurotransmitter test is a non-invasive diagnostic tool that can help identify these imbalances and provide valuable insights into an individual's brain chemistry. In this blog, we will explore the benefits of neurotransmitter testing and how it can help improve our mental health and well-being. Accurate Diagnosis: A neurotransmitter test can accurately diagnose the underlying...

Discover why topical testosterone replacement therapy is frequently over-prescribed and how outdated serum testing methods may fail to reflect true hormone bioavailability. Learn how saliva and dried blood spot testing provide a more accurate picture of tissue hormone delivery, why physiological testosterone dosing matters, and how excessive testosterone may suppress natural production, reduce receptor sensitivity, and impact long-term hormonal balance, energy, mood, libido, and overall men’s health.

 

Hot flashes and night sweats affect up to 80% of women during perimenopause — but they are not inevitable, and they are not forever. The root cause is hormonal imbalance, particularly the out-of-sync fluctuation of oestrogen and progesterone as the ovaries begin to wind down. Discover the lifestyle changes, natural supplements and hormone testing strategies that can bring real relief.

Perimenopause is far more than a reproductive transition — it is fundamentally neurological. As oestradiol declines, the brain’s bioenergetic system becomes compromised, neurotransmitter balance shifts, and the thermoneutral zone narrows, giving rise to hot flashes, mood instability, memory changes and sleep disruption. This article explores the neuroscience behind the menopausal transition and why hormone replacement therapy — timed correctly — may be the most effective intervention.
