Life stage
Perimenopause and supplements
Perimenopause is the transition leading up to menopause, when oestrogen falls and periods become irregular, often starting in a woman's 40s. Supplements do not treat it, but a balanced diet plus, where appropriate, magnesium, vitamin D, omega-3 or collagen are the categories women most often ask about. None replaces medical care, so speak to your GP or pharmacist.
What changes nutritionally
As oestrogen falls, several things that touch nutrition can shift. Bone density can start to decline more quickly, which is why bone-supporting nutrients such as calcium and vitamin D get more attention. Sleep and mood can become more changeable. Many women also notice changes in body composition, with muscle becoming a little harder to hold onto, which is why protein and resistance training come up so often.
None of this means a cupboard full of pills. It means a few categories are worth understanding so you can decide, with your GP or pharmacist, whether any of them fit your situation. The NHS guidance on the menopause and on vitamin D is a sensible starting point.
The supplement categories that matter
- Magnesium: EFSA-authorised claims include that it contributes to normal muscle and nervous-system function and to the reduction of tiredness and fatigue.
- Vitamin D: contributes to the maintenance of normal bones and muscle function. The NHS advises many UK adults consider a daily supplement in autumn and winter.
- Collagen: popular around skin and joints, though the claims often run ahead of the evidence; we explain what is and is not supported.
- Creatine: best known for high-intensity exercise performance, of interest to active women maintaining strength.
For an evidence-first overview, see our perimenopause supplements league table, which grades each category on its regulatory evidence and shows the cost per effective dose. Comparing individual products? See our roundups of the best magnesium for women, the best collagen in the UK and the best creatine for women. For the convenience of a single product, compare the best multivitamin for women, and our glossary explains terms like vasomotor symptoms and NRV.

Questions women actually ask
From our questions library, the ones that come up most at this stage: whether you can be perimenopausal without hot flushes, whether a Mirena coil can mask perimenopause, and why the 4am waking and anxiety pattern happens. On HRT specifically: whether you can get it over the counter and whether a GP can refuse it over a family history of breast cancer.
Where this fits across the life stages
Perimenopause sits between the reproductive years and menopause itself, and leads into the senior years. Earlier stages have their own priorities, covered in our pregnancy and postnatal guides.
Frequently asked questions
What is perimenopause?
Perimenopause is the transition leading up to menopause, when the ovaries gradually make less oestrogen and periods become less predictable. According to the NHS it often begins in a woman’s 40s, though it can start earlier, and it ends at menopause, which is reached 12 months after the last period.
Do I need supplements during perimenopause?
Not necessarily. A balanced diet covers most needs for most people. Some women find specific supplements helpful for general wellbeing, but supplements do not treat perimenopause and are not a substitute for medical care. Speak to your GP or pharmacist about what is right for you.
Which supplements do women look at most in perimenopause?
The categories women most often ask about are magnesium, vitamin D, omega-3 and collagen, plus protein and creatine for those who are active. We explain what the evidence supports for each, and where the claims go further than the evidence allows.
Can supplements replace HRT?
No. Supplements are not a replacement for hormone replacement therapy or any prescribed treatment. If you are considering options for perimenopausal symptoms, that is a conversation for your GP or a menopause specialist.
What is the average age for perimenopause?
The NHS says the menopause and the perimenopause leading up to it usually affect women between 45 and 55, though they can happen earlier. Perimenopause is the transition before periods stop completely, so it commonly begins in a woman’s 40s. Age varies a lot between individuals, and starting much earlier can have other causes worth discussing with a GP.
What are the first signs of perimenopause?
According to the NHS, one of the first signs of perimenopause is usually a change to your periods, which may become more or less frequent, heavier or lighter. Other commonly reported changes include hot flushes, night sweats, sleep problems, and shifts in mood or memory. These are general information points, not a diagnosis, so persistent or troubling symptoms are worth raising with your GP.
