Perimenopause collagen loss is not the same as normal ageing. Women lose approximately 30% of their skin collagen in the first five years after menopause — driven by oestrogen's direct role in signalling fibroblasts to produce collagen, elastin and hyaluronic acid. This is measurable, documented science. Here's the timeline of what's happening, what the evidence actually says about retinoids, HRT and collagen supplements (including the inconvenient funding-source data), and w

Oestrogen is a powerful anti-inflammatory hormone. When it declines in perimenopause, your body shifts into chronic low-grade inflammation — called inflammopause. It's the hidden driver behind joint pain, brain fog, fatigue and rising disease risk. A 2020 Journal of Neuroinflammation paper called perimenopause "a systemic inflammatory phase." Here's what that means for you — and what the evidence says to do about it.

In perimenopause, your muscles become resistant to protein signals a phenomenon called anabolic resistance driven by declining oestrogen. The standard RDA of 0.8g/kg/day was designed to prevent deficiency, not maintain muscle mass during hormonal transition. Research consistently supports 1.2–1.6g/kg/day for perimenopausal women roughly double the RDA. Timing matters too. Here's what the evidence says about how much perimenopause protein you actually need, when to eat it, and

Perimenopause vaginal dryness is part of a medical syndrome called GSM — Genitourinary Syndrome of Menopause — that also affects your bladder, urethra, sexual function and tissue health. Unlike hot flashes, GSM does not improve on its own. It progressively worsens without treatment. The 2025 AUA guideline — the most comprehensive ever produced — confirms safe, effective treatments exist, from local vaginal oestrogen to pelvic floor physiotherapy. Most women are never offered

Cardiovascular disease is the number one killer of women — not breast cancer. And the changes that raise that risk don't start at menopause. They start in perimenopause, quietly, while you're busy managing hot flashes and brain fog. Your LDL is rising. Your arteries are beginning to stiffen. Your blood pressure is creeping up. A landmark March 2026 JAMA Cardiology study confirms this is the window to act. Here's the science, what it means for your body right now, and what the

Magnesium deficiency in perimenopause is more common than you think—and it could be worsening your anxiety, sleep issues, hot flashes, and fatigue. As estrogen declines, your body loses more magnesium, increasing your need. This science-backed guide explains how low magnesium impacts your symptoms, the best forms to take, and how to restore optimal levels for better mood, sleep, and hormonal balance.

Your gut microbiome does far more than digest food — it's actively managing your oestrogen through a community of bacteria called the estrobolome. In perimenopause, declining hormones disrupt this microbial ecosystem, which then worsens hormone signalling in return. The result? A vicious cycle that may be driving your bloating, brain fog, hot flashes, mood crashes and weight gain harder than you realise. Here's the science — and what the evidence says actually helps.

The things that used to roll off you don't anymore. You are not weaker. Your stress regulation system has been neurobiologically reconfigured by perimenopause. The Swiss Perimenopause Study confirms cortisol rises during the transition — at the exact moment the sex hormones that buffer and modulate it decline. The HPA axis fires at lower thresholds. Recovery takes longer. The overnight cortisol nadir is disrupted. Here is the science of what changed — and the specific toolkit

Vitamin D perimenopause deficiency is more common than most women realize. As estrogen declines, your body becomes less efficient at activating vitamin D into its usable form. This means even with the same sun exposure and diet, levels can drop. Low vitamin D can worsen fatigue, mood changes, brain fog, and muscle weakness—symptoms often mistaken for perimenopause itself.

One glass hits like two at 44 — and that is not imagination. Perimenopause changes how your body metabolises alcohol through three simultaneous mechanisms: declining estrogen slows liver enzyme activity, reduced lean muscle mass lowers body water, and alcohol dehydrogenase production in women is already lower than men's. The result is higher blood alcohol concentration at equivalent doses and slower clearance. Alcohol also worsens hot flashes, sleep, and anxiety — the very sy
