Supplements for women
backed by the research
No marketing fluff. No pink tax. What women actually need for energy, hormonal balance, bone health, skin, and sleep — at doses that are clinically meaningful.
Iron supplement recommendations vary by age and menopausal status — always test before supplementing.
Women face distinct nutritional challenges throughout life
The NDNS found UK women are more likely to fall below reference intake for iron, magnesium, and iodine — while hormonal fluctuations amplify nutrient demands at every life stage from perimenopause onwards.

The 4 areas women should prioritise
Based on the most common nutritional gaps and health goals among UK women. Choose by what matters most right now.
Energy & hormonal balance
Fatigue is the number one health complaint among UK women. These are the nutritional reasons why.
Iron Bisglycinate 18mg
Iron deficiency anaemia affects 1 in 5 UK women. Bisglycinate form is significantly better tolerated than ferrous sulphate with less GI side effects.
B-Complex (methylfolate form)
Methylfolate (not folic acid) is the active form the body actually uses. Critical for energy metabolism and particularly important for women with the MTHFR gene variant.
Magnesium Glycinate 400mg
Addresses PMS symptoms including bloating, cramps, and mood changes. Studies show 360mg daily significantly reduces PMS severity.
Ashwagandha KSM-66 300mg
Regulates cortisol, which disrupts female hormonal balance. Clinical trials show improvements in thyroid health and adrenal function.
Bone, joint & long-term health
Women lose 20% of bone density in the 5–7 years after menopause. Starting earlier makes a significant difference.
Vitamin D3 4,000 IU + K2 100mcg
The K2 directs calcium to bones rather than arteries. D3 deficiency is near-universal in UK women October–April. Together they address two of the biggest long-term risks.
Calcium (from food + supplement if needed)
The research supports getting calcium from food first. Supplement only if diet is low — aim 700–1000mg total. Magnesium and K2 matter as much as calcium itself.
Omega-3 EPA/DHA 2g daily
Reduces joint inflammation. Strong evidence for mood regulation and reducing risk of postpartum depression. Cardioprotective effect increases post-menopause.
Collagen Peptides 10g
Specific collagen peptides studied for joint cartilage support and skin elasticity. Better absorbed as hydrolysed powder. Evidence improving for joint pain in particular.
Skin, hair & nails
The supplements with genuine clinical evidence — not the ones with the best marketing.
Biotin 5,000mcg
Deficiency is genuinely common in women. Clinical studies show improvements in nail thickness and brittleness. Hair benefit evidence is strongest in those with deficiency.
Vitamin C 1,000mg
Essential for collagen synthesis. Ascorbic acid is the research-tested form. Also enhances iron absorption when taken together — relevant for women with low iron.
Zinc Bisglycinate 25mg
Involved in keratin production and wound healing. Deficiency contributes to hair loss. Bisglycinate form has best absorption without the GI issues of zinc oxide.
Marine Collagen (Type I & III)
Type I collagen is the primary structural protein in skin. Marine sourcing has higher bioavailability than bovine. Studies show skin hydration improvements at 10g daily over 8+ weeks.
Cycle, sleep & stress
For the hormonal disruption that affects 75% of women's sleep quality.
Magnesium Glycinate 400mg before bed
The most evidence-backed sleep supplement for women. Regulates cortisol, reduces sleep latency, addresses PMS-related insomnia. Non-habit forming.
Evening Primrose Oil 1,000mg
GLA content shown to reduce breast tenderness and cycle-related symptoms in multiple trials. Most benefit seen with 3+ months of consistent use.
Saffron Extract 30mg (KSM-66)
The most evidence-backed botanical for low mood. Meta-analyses show comparable effect to low-dose SSRIs for mild-moderate depressive symptoms without side effects.
Vitamin B6 50mg (P5P form)
P5P (active B6) is essential for serotonin synthesis and PMS management. NHS acknowledges B6 may help PMS symptoms. Avoid high-dose (>100mg long term) — use P5P form.
Nutritional needs change across life stages
Iron, folate (methylfolate), D3, omega-3. Fertility preparation requires methylfolate 3+ months before conception. Bone density is still building — D3 + K2 + calcium-from-food matters now.
Perimenopause symptoms can start 10 years before menopause. Magnesium, ashwagandha, B6 (P5P), and omega-3 address the most evidence-backed interventions. Monitor iron — levels may change.
Stop iron unless tested deficient. Prioritise D3 + K2 + collagen for bone and joint health. CoQ10 becomes more relevant for cardiovascular support post-menopause. Omega-3 doses may increase.
What to skip (and why)
The women's supplement market is saturated with products designed around emotional appeals rather than evidence. Here's what we avoid stocking and why.
High-dose folic acid (not methylfolate) in pregnancy prep
Up to 40% of women carry MTHFR variants reducing their ability to convert synthetic folic acid. NHS guidance recommends folic acid, but methylfolate is better for the subset who cannot convert it. Speak to your GP.
Collagen supplements making disease claims
Collagen for skin hydration has emerging evidence. Claims about joint disease treatment or arthritis are not supported by current evidence at levels found in supplements.
Most female hormone-balancing blends
Proprietary 'hormone balance' blends typically have weak evidence for individual ingredients at the included doses. Magnesium, B6, and vitamin D have stronger individual evidence than most blends.
Iron supplements if you haven't confirmed deficiency
Iron overload is as dangerous as deficiency. Women aged 50+ don't lose iron through menstruation and should not supplement without a blood test confirming deficiency.
