# A Guide To Eating Well In Perimenopause: Understanding The Key Nutrients

As oestrogen drops during perimenopause, what your body needs from food shifts in specific ways. Your bone density, muscle, energy, and sleep can all be affected by changes in how you process certain nutrients. This article covers the nutrients that matter most through perimenopause, including calcium, vitamin D, protein, magnesium, and phytoestrogens, with specific targets and practical context to help you make informed choices about what you eat.

**Q: Do I need to take calcium supplements during perimenopause?**
A: For most people, you can meet the UK recommended daily intake of 700mg of calcium through food alone, using sources like dairy, fortified plant milks, tinned fish with edible bones, and leafy greens. A supplement is not automatically needed during perimenopause. If you have been diagnosed with osteoporosis, a higher daily target may apply, your GP can advise on the best approach for your situation.

As oestrogen falls, your bones lose density more quickly, your muscles get harder to hold onto, making certain nutrients increasingly important. Knowing the nutrients matter most through this time, and what the evidence says about targets and food sources, gives you something practical to work with when you adjust what you eat.

## Calcium and bone density during perimenopause

Oestrogen helps keep your bones forming and renewing, so as levels fall towards the end of your perimenopause years, bone loss speeds up. Over time this raises your risk of osteoporosis, where bones become weaker and more likely to break. Calcium is the main mineral in bone, so keeping your intake steady is a direct way to support your bones through this change.

The recommended daily intake for adults in the UK is 700mg of calcium, and you can usually reach this through food alone. Good sources include dairy, fortified plant milks, tinned fish with edible bones, tofu set with calcium sulphate, and green leafy vegetables like kale and broccoli.

> **WARNING**: If you have been diagnosed with osteoporosis, a higher daily intake of 1,000mg of calcium is recommended. If this applies to you, it is worth talking to your GP about how to reach that safely, rather than adjusting your intake based on this article alone.

## Vitamin D and why calcium cannot work without it

Calcium only protects your bones if your body can absorb it, and that is where vitamin D comes in. Without enough vitamin D, even a calcium-rich diet does little for your bone density.

The recommended daily intake is 10 micrograms (400 IU) of vitamin D for everyone aged 1 and over, all year round. From October to March in the UK, sunlight is rarely strong enough to keep your levels up, so a daily 10 microgram supplement is widely advised through those months. This advice applies to everyone, and it carries extra weight during perimenopause given how much supporting bone health matters at this stage.

You can get some vitamin D from food, including oily fish, eggs, and fortified foods, though diet alone rarely provides enough. If you have a health condition or take regular medication, it is worth checking with your GP before you start a vitamin D supplement.

## Protein and the challenge of maintaining muscle mass

Muscle naturally becomes harder to hold onto as you age, and this can speed up through the menopause transition. When that loss progresses significantly over time, it is called sarcopenia. Protein is the main thing in your diet that slows the decline, helping you keep both muscle and strength.

The general UK reference value for adults is 0.75g of protein per kilogram of body weight a day. During midlife and after menopause, a higher daily intake of 1.0g to 1.2g per kilogram may support muscle better. This higher range is not a formal UK government recommendation, though it increasingly shows up in specialist nutrition advice for this stage. If you want guidance on your own intake, you can raise it with your GP or a registered dietitian.

Good sources include meat, fish, eggs, dairy, legumes, tofu, and nuts. Spreading your protein across meals, rather than loading it into one sitting, helps your body use it to build and maintain muscle.

## Magnesium and what falling oestrogen may mean for your levels

Magnesium has a hand in your bone health, energy, muscle function, and sleep. Falling oestrogen may affect how magnesium is retained and excreted around menopause, although the evidence is limited and does not show that every woman’s magnesium requirements increase. Ensuring an adequate dietary intake remains important, particularly as protecting bone and muscle becomes more relevant through midlife

The recommended daily intake of magnesium for women in the UK is 270mg. You can find it in nuts and seeds, wholegrains, leafy green vegetables, pulses, and dark chocolate. If you eat a reasonable variety of these, you may not need a supplement, though if you are thinking about one, it is worth talking to a healthcare professional first.

## Phytoestrogens and what the evidence actually shows

Phytoestrogens are plant compounds with a structure similar to your own oestrogen. They can attach to oestrogen receptors in your body and produce weak, oestrogen-like effects. You will find them in soya products, linseeds, chickpeas, lentils, and some wholegrains.

Most of the interest in phytoestrogens is about whether they ease menopausal symptoms like hot flushes. The evidence here is mixed and far from settled. You may notice a difference, or you may not. Part of the reason is that phytoestrogens have to be converted into their active forms by your gut bacteria, and that process varies a lot from person to person depending on your gut microbiome. Phytoestrogens are not a replacement for hormone replacement therapy (HRT), and they are not a treatment for menopausal symptoms.

Including soya and other phytoestrogen-rich foods as part of a varied diet is still worthwhile nutritionally, even if the evidence on symptom relief stays uncertain.

If you want to look at your diet against these nutrient targets, a registered dietitian is the best person to help you do that. Your GP can also refer you if you have specific concerns about bone density, muscle health, or supplements.

## Frequently asked questions

**Q: Do I need to take calcium supplements during perimenopause?**

For most people, you can meet the UK recommended daily intake of 700mg of calcium through food alone, using sources like dairy, fortified plant milks, tinned fish with edible bones, and leafy greens. A supplement is not automatically needed during perimenopause. If you have been diagnosed with osteoporosis, a higher daily target may apply, your GP can advise on the best approach for your situation.

**Q: How much vitamin D should I take in the UK during autumn and winter?**

A daily supplement of 10 micrograms (400 IU) of vitamin D is widely advised for all adults in the UK through autumn and winter, from October to March, when sunlight is too weak for your body to make enough. This applies to everyone, not only during perimenopause. If you have a health condition or take regular medication, check with your GP before you start a supplement.

**Q: Can eating more phytoestrogens reduce hot flushes?**

The evidence on this is mixed. Phytoestrogens, found in foods like soya, linseeds, and lentils, can interact with oestrogen receptors in your body, but research on their effect on symptoms like hot flushes has been inconsistent. How much you notice may depend partly on your own gut bacteria, which affect how your body processes these compounds. Including phytoestrogen-rich foods in your diet is nutritionally reasonable, though they are not a clinical treatment for menopausal symptoms.

**Q: Why is the protein target for perimenopause higher than the general UK guideline?**

Through midlife and the menopause transition, muscle mass and strength can become harder to maintain, although factors such as ageing, physical activity and overall diet also play an important part. Some specialist guidance suggests that an intake of around 1.0g to 1.2g per kilogram may be appropriate for some women. This range is not a formal UK government recommendation, and research specifically establishing higher protein needs during perimenopause remains limited. A registered dietitian can help you work out an appropriate intake for your body weight, health and activity level.
