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

Hormones play a critical but often overlooked role in athletic performance, recovery, and injury risk. Testosterone, cortisol, oestrogen, progesterone, thyroid hormones, and vitamin D all influence energy metabolism, muscle building, and the body's ability to recover from training. When these hormones become dysregulated — through overtraining, energy deficiency, or underlying imbalance — performance suffers and injury risk rises. This article explains which hormones matter most for athletes, how overtraining syndrome develops, and why hormone testing is a valuable tool for optimising training and recovery.

PMS and PMDD are more than hormonal mood swings—they are complex neuroendocrine conditions driven by interactions between sex hormones and neurotransmitters like serotonin, GABA, and cortisol. This article explains the science behind menstrual mood disorders and highlights how advanced hormone and neurotransmitter testing from Hormone Lab UK and ZRT Laboratory can help identify imbalances and guide personalised treatment.

Mental health treatment is entering a new frontier — one that looks beyond the brain and into the bloodstream. Hormones and neurotransmitters, once seen as separate systems, are now recognized as deeply interconnected forces shaping both body and mind. Understanding and testing these biochemical messengers can transform how we approach depression, anxiety, and emotional disorders. 1. The Power of Hormone and Neurotransmitter Testing Hormone testing identifies imbalances in cortisol, estrogen, progesterone, testosterone, thyroid hormones, and others that can silently affect mood, sleep, and energy. Neurotransmitter testing complements this by measuring key brain chemicals such as serotonin, dopamine, GABA, and norepinephrine...

Explore the vital role of estrogen in perimenopause, its impact on mood, sleep, heart and bone health, and the latest research on hormone therapy options.

By Dr. Sherry LaBeck of ZRT Lab Perimenopause is the transition between a woman's reproductive years and menopause, characterized by a decline in estrogen levels, which can lead to physical and emotional symptoms. Understanding the role of estrogen during this phase is essential for managing symptoms and improving the quality of life for women going through this transition. What is Perimenopause? Perimenopause typically begins in a woman's 40s, though some may experience symptoms as early as their mid-30s, which is known as premature menopause. During this phase, the ovaries produce less estrogen until menstruation stops, marking the onset of menopause....
