Selenium is an essential trace element with a critical role in immune function, antioxidant defence, and thyroid health. Research links selenium deficiency to increased viral replication, more severe infection outcomes, and a higher likelihood of viral mutation into new strains. Heavy metal exposure from mercury and arsenic can further deplete selenium, compounding the risk. This article explains the science behind selenium’s role in viral protection, the geographical link between selenium-deficient soils and emerging infectious diseases, and how at-home ICP-MS testing can confirm whether your selenium levels are adequate.
Vitex agnus-castus — also known as chasteberry or chaste tree berry — is one of the most widely used botanical remedies for female hormone imbalance. Clinical research supports its use for reducing elevated prolactin, correcting luteal phase progesterone deficiency, alleviating PMS and PMDD symptoms, and managing some symptoms of the menopausal transition. This article reviews the evidence behind Vitex, explains the hormonal mechanisms through which it works, and outlines when it may be an appropriate botanical option for women with menstrual cycle disturbances.
Menopause is one of the most significant transitions in a woman’s life, yet it remains surrounded by confusion, misinformation, and unnecessary silence. From the first signs of perimenopause to postmenopausal symptoms such as vaginal dryness, hair loss, skin changes, and thyroid dysfunction, women deserve clear, honest, evidence-based answers. This article addresses the most frequently asked questions about menopause — covering what it is, when it happens, what causes its wide range of symptoms, and how comprehensive hormone testing can help women and their healthcare providers make informed decisions.
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...
Blue Zones are five regions of the world where people consistently live longer, healthier lives than anywhere else on the planet. From Sardinia to Okinawa, these communities share a set of lifestyle habits — around diet, movement, social connection, purpose, and stress — that collectively reduce the risk of heart disease, diabetes, and premature death. This article explores what Blue Zone communities have in common, the science behind why these habits work, and seven practical steps you can take to bring Blue Zone principles into your own daily life.
