What Vitamins Should I Take During Perimenopause?
What Vitamins Should I Take During Perimenopause? Your Complete Guide
Your nutritional needs are changing. Here's exactly what your body needs now.
If you've hit your 40s and suddenly feel like your usual diet and supplements aren't cutting it anymore, you're not imagining things.
Perimenopause changes your body's nutritional needs significantly. Hormonal shifts affect how you absorb nutrients. Stress depletes certain vitamins faster. And symptoms like fatigue, brain fog, and mood swings often have nutritional components.
The right vitamins and supplements won't eliminate every symptom (nothing can promise that), but they can provide your body with the foundation it needs to navigate this transition more smoothly.
This guide covers everything: which nutrients matter most, why they're particularly important now, how to choose quality supplements, and how to build a realistic routine you'll actually stick with.
Why Your Nutritional Needs Change During Perimenopause
Before we dive into specific vitamins, it helps to understand why perimenopause creates different nutritional demands:
1. Hormonal Changes Affect Nutrient Metabolism
Oestrogen influences how your body processes many nutrients. As levels fluctuate and decline:
- Vitamin D metabolism changes (bone health becomes crucial)
- B vitamin needs often increase (hormone metabolism requires them)
- Magnesium depletion accelerates (stress response uses it rapidly)
- Iron needs may decrease (lighter or absent periods) or increase (heavier bleeding)
2. Stress Depletes Key Nutrients
Perimenopause is often a high-stress life phase — juggling careers, ageing parents, teenagers, relationship changes, and your own symptoms. Chronic stress rapidly depletes:
- B vitamins (especially B5, B6)
- Magnesium
- Vitamin C
- Zinc
3. Absorption Efficiency Declines
As we age, our digestive efficiency typically decreases:
- Stomach acid production declines (affects B12, iron, calcium absorption)
- Gut microbiome changes (affects overall nutrient processing)
- Medication use may increase (many medications affect nutrient absorption)
4. Symptom-Specific Needs Emerge
Different perimenopause symptoms have different nutritional connections:
- Hot flushes → Phytoestrogens, magnesium, certain botanicals
- Brain fog → B vitamins, ginkgo, blood sugar regulation
- Fatigue → B vitamins, iron, chromium
- Mood swings → B6, magnesium, omega-3s
- Sleep problems → Magnesium, B vitamins
Essential Vitamins for Perimenopause
The B Vitamin Family: Your Energy and Mood Foundation
B vitamins are arguably the most important vitamin group during perimenopause. They're involved in energy production, nervous system function, hormone metabolism, and mood regulation.
Vitamin B6 (Pyridoxine)
Why it matters in perimenopause:
- Essential for producing serotonin, dopamine, and GABA (mood regulators)
- Supports hormone metabolism (helping your body process fluctuating hormones)
- May reduce PMS-like symptoms that often accompany perimenopause
Signs you might need more: Mood swings, irritability, brain fog, carpal tunnel-like symptoms
Food sources: Chicken, fish, potatoes, bananas, chickpeas
Supplement consideration: 10-50mg daily is typically recommended; higher doses should be supervised
Vitamin B12 (Cobalamin)
Why it matters in perimenopause:
- Critical for energy production at the cellular level
- Supports cognitive function and memory
- Required for healthy red blood cell formation
- Absorption declines significantly with age
Signs you might need more: Extreme fatigue, brain fog and memory issues, tingling in hands/feet, mood changes
Food sources: Animal products (meat, fish, eggs, dairy)
Supplement consideration: Essential for vegetarians/vegans; sublingual forms absorb better for those with digestive issues
Vitamin B5 (Pantothenic Acid)
Why it matters in perimenopause:
- Central to adrenal function (your stress response)
- Required for energy metabolism
- Supports hormone production
Signs you might need more: Fatigue despite adequate sleep, poor stress tolerance, digestive issues
Food sources: Widespread in foods; mushrooms, avocados, chicken, whole grains.
Vitamin B2 (Riboflavin)
Why it matters in perimenopause:
- Involved in energy production
- May help reduce migraine frequency (migraines often increase in perimenopause)
- Supports cellular function
Food sources: Dairy, eggs, lean meats, green vegetables
Biotin (B7)
Why it matters in perimenopause:
- Supports hair, skin, and nail health (all can be affected by hormonal changes)
- Involved in energy metabolism
- Blood sugar regulation
Signs you might need more: Hair thinning, brittle nails, skin issues
Getting Your B Vitamins: Our Menopause Gummies contain B2, B5, B6, B12, and Biotin — the full spectrum of B vitamins most important for perimenopause. Taking them together (as found in food) allows them to work synergistically.
Vitamin D: The Hormone Helper
Vitamin D acts more like a hormone than a typical vitamin, and it's crucial during perimenopause.
Why it matters in perimenopause:
- Bone health: Oestrogen decline accelerates bone loss; vitamin D is essential for calcium absorption
- Mood support: Deficiency linked to depression and mood disorders
- Immune function: Supports overall immune health
- Muscle function: Reduces fall risk
The perimenopause problem: Many women are deficient, especially in northern climates with limited sun exposure.
Testing: Ask your GP for a vitamin D test — it's worth knowing your actual levels.
Supplement consideration: 1000-4000 IU daily is common; take with fat for absorption; vitamin D3 is preferable to D2
Vitamin C: More Than Immunity
Why it matters in perimenopause:
- Adrenal support: Your adrenals use significant vitamin C, especially during stress
- Collagen production: Supports skin elasticity (which declines with oestrogen loss)
- Iron absorption: Important if you're supplementing iron
- Antioxidant protection: Combats oxidative stress
Food sources: Citrus, berries, peppers, broccoli, tomatoes
Supplement consideration: 500-1000mg daily is common; divided doses absorb better than single large doses.
Vitamin A: Skin and Immune Support
Why it matters: Supports skin health during hormonal changes, immune system function, vision health
Caution: Don't oversupplement — vitamin A is fat-soluble and can accumulate. Beta-carotene (a precursor) is safer in high doses.
Vitamin E: Antioxidant and Potential Hot Flush Support
Why it matters: Antioxidant protection for cells, some evidence it may help reduce hot flush severity, supports skin health
Food sources: Nuts, seeds, olive oil, avocados
Supplement consideration: 200-400 IU daily if supplementing; natural (d-alpha) form preferred over synthetic
Essential Minerals for Perimenopause
Magnesium: The Master Mineral
If there's one mineral virtually every perimenopausal woman should consider, it's magnesium.
Why it matters in perimenopause:
- Sleep support: Promotes relaxation; helps with insomnia
- Stress response: Calms the nervous system
- Muscle relaxation: Reduces cramps and tension
- Bone health: Works with calcium and vitamin D
- Mood regulation: Supports neurotransmitter function
- Hot flushes: May help reduce intensity
The deficiency problem: Up to 80% of people don't get enough magnesium from diet. Stress depletes it rapidly. Absorption declines with age.
Signs you might need more: Poor sleep, muscle cramps or tension, anxiety or restlessness, headaches, constipation
Forms of magnesium:
- Oral supplements: Glycinate (good absorption, calming), citrate (good absorption, can loosen stools), oxide (cheaper but poor absorption)
- Transdermal body mists: A body mist, simply sprayed on, with nothing to swallow; a lovely ritual alongside your diet

Topical Magnesium Option: If tablets aren't your thing, a magnesium chloride body mist is a gentle way to bring magnesium into your self-care routine. There are only a few studies on skin absorption and their findings vary, so check in with your GP or pharmacist before relying on one, especially if you're on medication. All four of our mists contain magnesium chloride: Sleep Hero (evening wind-down), Flame Fighter (a cooling spritz for warm moments), Revitalise Pro (tired muscles) and our new Ease Hero (an alternative option to Revitalise Pro with more cooling intensity; contains wintergreen, so it isn't suitable if you're allergic to aspirin or on blood thinners; patch test first).

Zinc: Hormone and Immune Support
Why it matters: Essential for hormone production, immune function, wound healing and skin health, taste and appetite regulation
Signs you might need more: Frequent illness, slow wound healing, hair loss, loss of taste/smell
Food sources: Oysters (highest), red meat, chicken, beans, nuts, dairy
Supplement consideration: 15-30mg daily; don't oversupplement as zinc can deplete copper
Chromium: Blood Sugar Balance
Why it matters: Helps regulate blood sugar (issues often emerge during perimenopause), supports stable energy, may help reduce cravings
Food sources: Broccoli, whole grains, grape juice, potatoes
Supplement consideration: 200-400mcg chromium picolinate or chromium yeast is typical
Iron: A Nuanced Mineral
Why it matters (and when it doesn't):
- If you're still having periods (especially heavy ones), iron deficiency is possible
- Once periods stop, iron needs typically decrease
- Deficiency causes fatigue, weakness, brain fog
- Don't supplement unless tested — iron overload is harmful
Always test: Get serum ferritin checked before supplementing iron
Calcium: Bone Protection
Why it matters: Bone loss accelerates as oestrogen declines, works with vitamin D and magnesium, supports muscle and nerve function
Best approach: Food sources (dairy, fortified foods, leafy greens) are preferable to large-dose supplements. If supplementing, smaller divided doses absorb better.
Beneficial Botanicals for Perimenopause
Beyond traditional vitamins and minerals, certain plants offer targeted support for menopause symptoms.
Sage Extract (Salvia officinalis)
Evidence for: Hot flushes, night sweats, excessive sweating
The research: Multiple clinical studies show sage can significantly reduce hot flush frequency and intensity — some by up to 50%.
How it works: Sage contains compounds with mild oestrogenic activity and affects the thermoregulation centre.
Red Clover Extract (Trifolium pratense)
Evidence for: Hot flushes, hormonal balance
The research: Contains isoflavones (phytoestrogens) that have been studied for menopause symptom relief with mixed but generally positive results.
How it works: Isoflavones have mild oestrogen-like effects, providing gentle hormonal support.
Evening Primrose Oil
Evidence for: Hormonal balance, mood, skin health
The research: Traditional use is strong; clinical evidence is moderate but promising.
How it works: Rich in GLA (gamma-linolenic acid), which supports prostaglandin production and hormonal balance.
Ginkgo Biloba
Evidence for: Brain fog, memory, cognitive function
The research: Well-researched for cognitive support generally; specific menopause research is limited but promising.
How it works: Supports blood flow to the brain; antioxidant effects.

Cranberry Extract
Evidence for: Urinary tract health
The research: Well-established for UTI prevention.
How it works: Contains compounds that prevent bacteria from adhering to urinary tract walls.
The All-in-One Approach: Why Combination Formulas Make Sense
Taking 10 different supplements is expensive, complicated, easy to forget, and often unnecessary.
The case for comprehensive formulas:
Synergy: Nutrients work together; combinations are often more effective than isolated nutrients
Convenience: One product instead of many
Compliance: You'll actually take them consistently
Cost-effective: Usually cheaper than buying separately
Balanced formulation: Designed to avoid conflicts or imbalances
Building Your Perimenopause Supplement Routine
Start With Foundations
Before adding targeted supplements, ensure your basics are covered:
Priority 1: The Non-Negotiables
- Comprehensive multi or menopause formula (covering B vitamins, key minerals)
- Vitamin D (especially in UK/northern climates)
- Magnesium (if not in your multi)
Priority 2: Based on Symptoms
- Hot flushes → Ensure sage and red clover in your formula
- Brain fog → Ensure ginkgo biloba and B vitamins
- Fatigue → Check B12 levels; ensure chromium
- Mood issues → B6; consider evening primrose
- Urinary problems → Cranberry extract
Priority 3: Additional Support
- Omega-3s (if not getting from diet)
- Calcium (if dietary intake is low)
- Iron (only if tested and deficient)
Give It Time
Supplements aren't instant fixes:
- Week 1-2: Building nutrient levels
- Week 4-6: Subtle improvements may appear
- Week 8-12: More noticeable benefits
- Ongoing: Maintenance and continued support
Internal + External: The Complete Approach
Oral supplements provide systemic, foundational support. Many women also love building topical rituals around them:
Hot flushes: Internal botanicals + a cooling spritz
Sleep: Internal B vitamins + topical magnesium with calming botanicals
Joint/muscle pain: Internal anti-inflammatory support + a muscle-massage ritual with Revitalise Pro or Ease Hero
Our Unshrinkables love using both together.
