Melatonin is far more than a sleep hormone. As a potent antioxidant, anti-inflammatory agent, and immune modulator, melatonin plays a critical role in protecting against oxidative stress, suppressing harmful inflammatory pathways, and supporting the body’s defence against viral infection. Melatonin production declines progressively with age — a pattern that mirrors the increased vulnerability to severe illness seen in older adults. This article explores the science behind melatonin’s immune and anti-inflammatory functions, the relationship between melatonin decline and age-related disease risk, how to support melatonin production naturally, and how at-home testing can confirm whether your melatonin levels are adequate.

Hormonal acne is one of the most common and frustrating skin conditions affecting women across all life stages — from puberty and perimenopause to post-pill breakouts and PCOS. At its root, acne is an inflammatory condition driven by androgen excess, sebum overproduction, skin microbiome disruption, and immune activation. Diet, gut health, and hormonal imbalances all play interconnected roles. This article explains the science behind hormonal acne, the key hormones involved, the role of diet and the microbiome, and how targeted hormone testing can identify the specific drivers of your breakouts.

Iodine deficiency is a significant and underappreciated global health problem, with urinary iodine levels in many Western populations having fallen substantially over recent decades. As an essential component of thyroid hormones, iodine deficiency impairs thyroid function, promotes goitre, and has wide-ranging consequences for metabolism, cognitive development, breast health, and reproductive health. Women of childbearing age are particularly vulnerable. This article explains the causes and consequences of iodine deficiency, who is most at risk, and how at-home dried urine testing using ICP-MS analysis can accurately confirm your iodine status.

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.
