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...

Many women going through menopause notice changes in their ability to remember things — and this is not just in their heads. A small, seahorse-shaped structure in the brain called the hippocampus is highly dependent on estrogen for synaptic plasticity, memory formation and neuroprotection. In this article, Margaret Groves of ZRT Laboratory explains the science behind menopause-related memory changes, why estrogen receptor expression declines with age, and why the “window of opportunity” for hormone replacement is critical to preserving cognitive function.

Discover why topical testosterone replacement therapy is frequently over-prescribed and how outdated serum testing methods may fail to reflect true hormone bioavailability.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.
