Perimenopause Support

Perimenopause is not a disease. It is a transition — sometimes gradual, sometimes abrupt, always individual. Your symptoms are real, they are physiological, and they are addressable.

The Foundation — Start Here

Before picking a symptom stack, make sure these three bases are covered. They work together and underpin everything else — especially during hormonal transition.

  • Vitamin D3 — a hormone precursor, not just a vitamin. Deficiency is strongly linked to mood disorders, bone loss, immune dysregulation, and worsening perimenopausal symptoms. Most women are deficient.
  • Magnesium Glycinate — D3 cannot be properly utilised without adequate magnesium. Also essential for sleep, mood, muscle relaxation, and nervous system regulation — all of which are disrupted in perimenopause.
  • Vitamin K2 — works synergistically with D3 and supports bone density — a critical concern as oestrogen declines.

Think of these as the soil. Everything else grows better when the foundation is right.

If You Could Only Choose One More Product

Progest-E Replenishing Oil

The hormonal hallmark of perimenopause is progesterone declining faster than oestrogen — creating a state of relative oestrogen dominance even as both hormones fluctuate. This drives the majority of perimenopausal symptoms: hot flushes, night sweats, anxiety, poor sleep, mood instability, and weight changes. Progest-E is a bioidentical progesterone oil that addresses this directly. Once your foundation is in place, this is your most impactful next step.

Quick Start — What's Bothering You Most?

Pick your biggest symptom and start there. Two or three products is all you need.

Start with one cluster. Give it 2–4 weeks. Your body will tell you what it needs next.

Perimenopause typically begins in the mid-to-late 40s but can start earlier. It is characterised by fluctuating and eventually declining oestrogen and progesterone, with progesterone usually declining first and fastest. This hormonal shift affects virtually every system in the body — brain, bones, cardiovascular system, thyroid, adrenals, gut, and skin.

The Root Causes We're Addressing

  • Progesterone decline — the first and most impactful hormonal shift. Drives anxiety, insomnia, hot flushes, and mood instability. Progest-E and Chaste Tree address this most directly.
  • Oestrogen fluctuation — erratic oestrogen (not just low oestrogen) drives hot flushes, night sweats, and brain fog. Red Clover and Sage provide phytoestrogenic and thermoregulatory support.
  • Adrenal transition — as ovarian hormone production declines, the adrenal glands become the primary source of sex hormones. Adrenal health is critical. Ashwagandha KSM-66, Rhodiola, and Adrenal Support Extract support this transition.
  • Thyroid disruption — oestrogen fluctuation directly affects thyroid function. Iodine, Bladderwrack, and Selenium support healthy thyroid hormone production and conversion.
  • Bone density loss — oestrogen is bone-protective. As it declines, bone resorption accelerates. D3, K2, Boron, and Magnesium are the non-negotiable bone support stack.
  • Cognitive changes — oestrogen supports neuroplasticity and neurotransmitter function. Bacopa, Gotu Kola, and Glycine support cognitive resilience during this transition.
  • Sleep disruption — driven by progesterone decline, cortisol dysregulation, and night sweats. Passionflower, Glycine, Lemon Balm, and Progest-E address the multiple drivers.

Key Nutrient Deficiencies in Perimenopause

Nutrient Role in Perimenopause Symptoms if Deficient Food Sources
Iron Prevents anaemia from heavy periods/menorrhagia Fatigue, dizziness, hair loss, shortness of breath Nettle, meat, liver, spinach + Vitamin C
Vitamin D Bone health, mood, immunity; drops post-menopause Bone pain, depression, muscle weakness Sun, fatty fish, fortified foods
Magnesium Sleep, anxiety, muscle cramps, blood sugar control Insomnia, irritability, palpitations Nuts, seeds, leafy greens, dark chocolate
B Vitamins (B6, B12, folate) Hormone metabolism, energy, neurotransmitter balance Brain fog, low mood, exhaustion Eggs, meat, leafy greens, fortified cereals
Zinc Hormone synthesis, skin repair, immunity Acne, slow wound healing, hair thinning Oysters, beef, pumpkin seeds, lentils
Omega-3 Reduces inflammation, supports brain/mood Joint pain, brain fog, hot flush severity Fatty fish, flaxseeds, walnuts

Evidence-Based Supplement Recommendations

Supplement Dose Targets Evidence Notes
Magnesium glycinate 300–400mg/day Sleep, anxiety, cramps, hot flushes Supports over 40% of women with low magnesium levels
Vitamin D3 + K2 1000–5000 IU D3 + 100mcg K2 Bone health, mood, immunity Low D3 associated with fatigue and low mood; K2 directs calcium to bones
B Complex (methylated) 1 cap/day Energy, mood, sleep, mental clarity Supports serotonin and dopamine pathways; methylated forms bypass MTHFR
Nettle Extract 1–2ml, 1–2x daily Iron replenishment, energy, heavy periods, vitality Nettle is nature's most bioavailable plant iron source — far better absorbed than isolated iron supplements, which are poorly tolerated and often ineffective. Pair with Vitamin C for optimal absorption.
Omega-3 Brussels sprouts, algae, chia, flax & hemp seeds, walnuts Inflammation, joint comfort, mood, mental clarity Associated with reduced hot flush intensity; supports cognitive function
Zinc 15–30mg/day Skin, immunity, hormone balance Do not exceed — high zinc may affect copper balance

Dr. Ray Peat's Metabolic Perspective on Perimenopause

The late Dr. Ray Peat — biologist, researcher, and pioneer of pro-metabolic nutrition — viewed perimenopause not as a simple hormone shortage, but as a metabolic and cellular energy challenge. His framework offers a compelling lens for women who feel their symptoms go deeper than conventional explanations suggest.

The Core Idea

According to Dr. Peat, the perimenopausal transition is driven less by falling oestrogen and more by progesterone declining first — leaving oestrogen relatively unopposed. He argued that excess oestrogen, rather than its absence, is what impairs mitochondrial function and drives the fatigue, mood changes, weight shifts, and cognitive fog so many women experience. The protective hormones, in his view, are progesterone and pregnenolone.

The Metabolic Foundation (Dr. Peat's Dietary Approach)

Dr. Peat emphasised that cellular energy production — not hormone replacement — is the foundation of hormonal resilience. His pro-metabolic dietary principles:

  • Carbohydrates — ripe fruits, orange juice, honey, and white sugar to fuel the thyroid and prevent cortisol surges from low blood sugar.
  • Protein & calcium — milk, cheese, orange juice, and collagen; 80g quality protein daily as a baseline.
  • Fats — saturated only — coconut oil and butter. PUFAs actively avoided — they block thyroid hormone secretion and raise oestrogen.
  • Salt — used liberally to support adrenal and thyroid function
  • Avoid — starches, raw vegetables, excessive fibre, and anything that suppresses thyroid or raises oestrogen

Hormonal Support (Dr. Peat's Approach)

  • Progest-E (topical bioidentical progesterone) — Dr. Peat's own formulation; his primary recommendation for oestrogen dominance and perimenopausal symptoms.
  • Thyroid support — a practical supplement option is Thyroid Energy — combining iodine, selenium, zinc, B vitamins, and Ashwagandha to support thyroid hormone production and T4→T3 conversion.
  • Pregnenolone / DHEA — used cautiously as upstream hormone precursors when thyroid support alone is insufficient

Lifestyle Principles (Dr. Peat)

  • Red light therapy — supports mitochondrial function and thyroid activity
  • Vitamin E (mixed tocopherols) — protective against PUFA oxidation in tissues
  • Aspirin & caffeine — used in small amounts for their anti-inflammatory and metabolic-supporting properties
  • Daily carrot salad — raw carrot with coconut oil and vinegar; binds and clears excess oestrogen from the gut
  • Stress reduction — sleep, warmth, and gentle movement to lower cortisol and support progesterone
  • Cascara Sagrada — Dr. Peat's preferred herbal support for sluggish bowel motility during this transition

Dr. Peat on Hot Flushes

Dr. Peat viewed hot flushes not as an oestrogen withdrawal symptom, but as a blood sugar and adrenal event. His immediate protocol: a small snack of sugar and salt before bed, combined with Thyroid Energy and progesterone support.
