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

In their conversation, McAvoy and Dr. Zava discuss his early research, the development of non-invasive hormone testing through saliva, and how this has revolutionized how clinicians understand hormone health. Dr. Zava also touches on his significant findings regarding the metabolism of estrogen and how lifestyle factors can influence cancer risk. He reflects on the challenges he faced in the early days of ZRT Laboratory, including financial struggles, but also shares the satisfaction of making a real difference in the lives of patients and healthcare providers.

For McAvoy, Dr. Zava’s work has been instrumental in shaping his own approach to patient care. ZRT's comprehensive hormone testing, including their Hormone Profile III, has helped countless practitioners like McAvoy identify hormonal imbalances and tailor treatments that improve patient well-being.

To learn more about Dr. Zava’s remarkable journey and the transformative work being done at ZRT Laboratory, read the full interview below.

Hormones are like the body's messengers, orchestrating various physiological processes. While they play essential roles in growth, metabolism, and reproduction, they also have a profound impact on your mood and emotions. The delicate balance of hormones can sway your emotional state, leading to mood swings, irritability, or even mood disorders. In this blog, we'll explore the intricate relationship between hormones and mood changes. 1. The Key Mood-Modulating Hormones Several hormones have a direct influence on your mood:a. Serotonin: Often referred to as the "feel-good" hormone, serotonin plays a crucial role in regulating mood. Low serotonin levels are associated with depression,...

Perimenopause, also known as the menopausal transition, is a natural and normal part of a woman's life. It refers to the years leading up to menopause, which is defined as the point at which a woman has not had a menstrual period for 12 consecutive months. Perimenopause typically begins in a woman's 40s but can start as early as the mid-30s. During perimenopause, the body's production of estrogen and progesterone, two hormones essential to a woman's reproductive system, begins to decline. This decline can cause a range of symptoms, including hot flashes, night sweats, mood swings, sleep disturbances, vaginal dryness,...

By Dr.David Zava, ZRT Laboratory In 2002 several large-scale clinical studies were published on the risks of breast cancer in postmenopausal women using conventional FDA-approved hormone therapy. These were the Women’s Health Initiative (WHI) and Million Women’s studies of women using FDA-approved estrogens and progestogens in the United States and Great Britain, respectively [1,2]. Both studies came to the same conclusion – that estrogen therapy, mostly in the form of oral conjugated equine estrogens, by itself did not significantly increase the risk of breast cancer and, to the surprise of many, was associated with a lower risk. However, when estrogen was...

By David Zava, ZRT Laboratory Delivery of the bioidentical hormones estradiol (E2), progesterone (Pg), and testosterone (T) through the skin as a cream or gel (topically) has become a mainstay of bioidentical hormone replacement therapy (BHRT) for women and men. A plethora of FDA-approved pharmaceuticals, compounded, and even over-the-counter topical BHRT products are available. The popularity of these products lies not only in their ease of use but in proven clinical efficacy [1-5] in treating hormonal deficiencies mostly brought on by ageing of the female (menopause) and male (andropause) reproductive systems. Dosing for Optimal Clinical Benefit Over the past 30 or so...
