Why a Hormone Profile Is Better Than a Single Test. When men experience hormone-related symptoms (like low libido, fatigue, weight gain, or mood changes), it’s rarely just one hormone causing the issue. A simple testosterone check may miss the bigger picture.

How Neurotransmitter Imbalances Affect Health. When neurotransmitters are out of balance, your brain and body may become over- or under-stimulated. Common scenarios include: Anxiety & Depression, Chronic Fatigue, Impulsivity, Insomnia, PMS & PMDD..

Infertility is an increasingly common issue, affecting over 22% of married women who struggle to conceive or carry a pregnancy to term. While physical causes like anovulation, tubal damage, or endometriosis account for many cases, hormonal imbalances are often overlooked yet highly treatable contributors to infertility. The ZRT Fertility Profile offers a comprehensive and convenient way to evaluate hormone levels that are essential for conception and pregnancy maintenance. By testing markers like FSH, LH, estradiol, progesterone, testosterone, thyroid hormones, and cortisol, this profile helps identify conditions such as ovarian insufficiency, luteal phase deficiency, PCOS, thyroid dysfunction, and stress-related hormonal disruption. Samples can be collected easily at home through fingerstick blood and saliva on specific days of the menstrual cycle, ensuring accurate and timely results. Early identification of hormonal imbalances empowers women to take corrective action—often through simple lifestyle changes or targeted therapies—before turning to more invasive fertility treatments. Whether you’ve been trying to conceive without success, experienced recurrent miscarriages, or are planning ahead for pregnancy, ZRT’s Fertility Profile provides critical insights to help you and your healthcare provider take proactive steps toward reproductive health and success.

Title: Understanding CardioMetabolic Risk – A Silent Threat We Can’t Ignore The rise in cardiovascular disease (CVD), obesity, and type 2 diabetes (DM2) is one of the most pressing health concerns of our time. CVD remains the leading cause of death for both men and women in the United States. Alarmingly, obesity and insulin resistance—precursors to DM2—significantly increase the risk of developing CVD. Yet, these conditions are largely preventable with early detection and lifestyle changes. So, how can we spot the danger before it's too late? What is CardioMetabolic Risk? Cardiometabolic risk refers to a cluster of modifiable risk factors...

By Dr.Tracy Tranchitella, ND-ZRT Laboratory Non-Alcoholic Fatty Liver Disease (NAFLD) has become a primary cause of chronic liver disease, impacting a large portion of the global population. NAFLD is characterized by the buildup of excess fat in the liver, unrelated to alcohol use, and is strongly associated with metabolic syndrome—a group of conditions that raise the risk of heart disease, stroke, and diabetes. Factors contributing to metabolic syndrome may also play a role in the development of NAFLD, but underlying endocrine disorders can further drive the onset and progression of this widespread liver condition. Moreover, environmental and chemical toxins may...
