Women's Hormonal Health Across Life Stages: What the Science Says

Women's health shifts with hormones — across the menstrual cycle, through perimenopause, into post-menopause. Each transition affects energy, mood, bone density, and cardiovascular health in ways that are well-documented and, importantly, addressable through nutrition and lifestyle. This article reviews the factors with the strongest research backing.

Iron, Zinc and Selenium: EFSA-Authorised Health Claims

Iron deficiency is the most common micronutrient deficiency in women of reproductive age. The WHO estimates iron-deficiency anaemia affects approximately 30% of women globally (WHO, 2023). The European Food Safety Authority (EFSA) confirms that iron contributes to normal formation of red blood cells and haemoglobin, and to the reduction of tiredness and fatigue. EFSA also recognises authorised health claims for zinc (contributes to normal DNA synthesis and maintenance of normal hair, nails and skin) and selenium (contributes to normal thyroid function and protection of cells from oxidative stress) — both particularly relevant across the different hormonal stages of a woman's life.

Intimate Hygiene and the Vaginal Microbiome

The vaginal microbiome is dominated by Lactobacillus species that maintain an acidic pH of 3.8–4.5, protecting against pathogenic colonisation. A 2021 review in Molecules found that botanical extracts such as calendula and chamomile have documented soothing properties for sensitive mucosal tissue (Juric et al., 2021). The EMA recommends pH-balanced, fragrance-free formulations for intimate care products.

Bone Health After 35

Peak bone mass is reached by approximately age 30. After menopause, declining oestrogen accelerates bone loss. EFSA confirms that calcium and vitamin D contribute to the maintenance of normal bone health. The practical implication: adequate intake throughout adulthood matters far more than supplementing only after problems appear (EFSA, 2010).

Sleep and Hormonal Balance

Sleep deprivation disrupts the HPA axis and reproductive hormones. Research published in the Journal of Clinical Endocrinology and Metabolism showed that restricted sleep elevates cortisol in women and impairs hypothalamic-pituitary axis recovery (Leproult and Van Cauter, 2010). This is not a minor effect — poor sleep in perimenopause can amplify hormonal symptoms considerably.

The evidence points in a consistent direction: iron, calcium, zinc, and selenium each have EFSA-confirmed roles relevant to women's health; pH-balanced intimate hygiene supports the natural vaginal microbiome; and quality sleep is integral to hormonal regulation. Small, consistent choices across these areas add up across a lifetime.
