The menopause supplement market is enormous and largely unregulated, and as a pharmacist I find most of it frustrating. Some of it has genuine evidence. Most of it is expensive urine.
Here is my honest assessment, and the principle I would apply before buying anything: test first, supplement second. Correcting a real deficiency produces a visible change. Topping up something you already have enough of does not.
And one thing worth saying at the top rather than burying at the bottom: the best-evidenced intervention for menopausal skin is not a supplement at all. It is daily broad-spectrum sun protection — the Gluten-Free Vegan Mineral SPF 50 Moisturizer, or any mineral SPF you will actually wear. If your budget is finite, that is where the first money goes, before anything below.
Worth testing before you supplement
Iron — ask for ferritin specifically
The one I would check first in any perimenopausal woman. Heavy or prolonged perimenopausal bleeding makes iron deficiency very common, and it causes hair shedding, brittle nails, fatigue and poor skin quality. Ferritin can be low while a standard full blood count looks normal — so ask for ferritin by name.
Do not supplement iron without testing. Excess iron is genuinely harmful, and iron supplements cause constipation and nausea in a lot of people.
Vitamin D
Deficiency is common, particularly in anyone practising careful sun avoidance — which is most people reading skincare advice. Relevant for barrier function and immune regulation, and important for bone health post-menopause, which matters considerably more than the skin argument. Worth testing and correcting.
Vitamin B12
Worth checking if you are vegan, over 50, on metformin, or on long-term acid-suppressing medication. Deficiency causes skin, nail and neurological changes.
Thyroid function
Not a supplement, but the single most valuable test on this list. Thyroid disease is common in women at this age and produces dry skin, hair loss and brittle nails that no supplement will fix.
Reasonable evidence
Collagen peptides
Better than I expected, weaker than the marketing. Several randomised trials show modest improvements in skin elasticity and hydration with hydrolysed collagen peptides, typically 2.5 to 10g daily over 8 to 12 weeks. Caveats worth knowing: many trials are industry-funded, effect sizes are small, and the mechanism is debated — ingested collagen is digested into amino acids and small peptides, so it does not arrive at your skin intact. The plausible explanation is that certain peptide fragments act as signalling molecules.
Reasonable to try. Do not expect it to replace sunscreen or a retinoid, and be aware most collagen is marine or bovine — relevant if you are vegan or have a fish allergy.
Omega-3 fatty acids
Essential fatty acids are structural components of the skin barrier and cannot be synthesised by the body. Reasonable evidence for barrier function and for dry eye, which is common after menopause. Note the mild antiplatelet effect — mention it to your doctor if you are on blood thinners or bruise easily.
Biotin
Genuinely reasonable evidence for brittle nails specifically — several small studies show improved thickness and reduced splitting over about six months. Little evidence for hair unless you are deficient, which is rare.
Important: biotin interferes with several laboratory immunoassays, including thyroid function tests and troponin. This can produce seriously misleading results — falsely normal or falsely abnormal. Tell your doctor you take it, and stop it a few days before blood tests if advised.
Weak or insufficient evidence
- Hyaluronic acid supplements. Some small studies, mostly industry-funded, mechanistically questionable. Topical works; oral is unconvincing.
- “Hair, skin and nails” combination products. Usually large doses of biotin plus small doses of everything else. You are mostly buying the biotin.
- Most menopause-branded blends. Proprietary formulas that do not disclose individual doses. If a product will not tell you how much of the active it contains, treat that as an answer.
- Phytoestrogens and isoflavones for skin specifically. Some evidence for hot flushes, little for skin.
- Antioxidant megadoses. High-dose vitamin E has been associated with increased bleeding risk and no consistent skin benefit.
Where the money is better spent
The interventions with the strongest evidence for menopausal skin are not supplements at all:
- Daily broad-spectrum SPF — the highest-return thing you can do, by a distance.
- A retinoid, used consistently at a tolerable frequency — the Wrinkle Repair Retinol Night Cream.
- Barrier repair — ceramides, glycerin, occlusives, applied to damp skin. The Rich Calming Cream addresses dryness, itching and new sensitivity together.
- Sleep and not smoking. Both have larger skin effects than anything in a bottle.
- Adequate dietary protein. More useful than collagen powder for most people, and cheaper.
Before you buy anything
- Tell your doctor and pharmacist everything you take, including supplements. Interactions are real and under-reported.
- Check for interactions with blood thinners, thyroid medication and anything else you are prescribed.
- Look for third-party testing, since supplement regulation is limited.
- Give anything three months before judging it, and change one thing at a time.
- Be sceptical of anything sold with a menopause photo and no dose disclosure.
Frequently Asked Questions
Do collagen supplements actually work for skin?
Modestly, and less than the marketing suggests. Several randomised trials show small improvements in elasticity and hydration at 2.5 to 10g daily over 8 to 12 weeks — but many are industry-funded and the mechanism is debated, since ingested collagen is digested rather than delivered intact. Reasonable to try; not a substitute for sunscreen or a retinoid.
Which supplements are actually worth taking in menopause?
Ones that correct a measured deficiency — which is why testing comes first. Ferritin, vitamin D, B12 and thyroid function are the ones worth checking. Beyond that, biotin has reasonable evidence for brittle nails and omega-3 for barrier function and dry eye.
Why does biotin matter for blood tests?
Because it interferes with several laboratory immunoassays, including thyroid function and troponin, and can produce falsely normal or falsely abnormal results. It is rarely mentioned on the packaging. Tell your doctor you take it, and stop a few days before testing if advised.
Are menopause supplement blends worth the money?
Usually not. Most are proprietary formulas that do not disclose individual doses — and if a product will not tell you how much of the active ingredient it contains, treat that as the answer. “Hair, skin and nails” products are typically a large biotin dose plus token amounts of everything else.
