Magnesium is often called a "wonder nutrient" — and for good reason.

It's involved in more than 300 biochemical reactions in the body, including the systems that regulate sleep, stress, hormones and nervous system balance.

In this episode we look at why magnesium is particularly important for women, especially if you're struggling with sleep, stress, PMS or the hormonal changes of perimenopause and menopause.

Magnesium helps activate the parasympathetic nervous system (your "rest and digest" mode), supports calming neurotransmitters like GABA, and plays an important role in melatonin production, all essential for good quality sleep.

In this episode we explore:

• Why magnesium levels can fluctuate during the menstrual cycle • How magnesium supports mood, sleep and PMS symptoms • The connection between magnesium, vitamin D and bone health • Why magnesium needs often increase during perimenopause • The different forms of magnesium and which ones actually work • Food sources that can help increase your intake naturally

A big thank you to our podcast sponsors Revive Active for supporting the Fab Female Nutrition podcast. Their magnesium complex combines several well-absorbed forms of magnesium designed to support energy, muscle function and nervous system balance - it's the one I choose to support my own health.

If sleep has been feeling elusive, this episode will help you understand why, and what simple steps might help.

Phytoestrogens are often misunderstood.

Do they increase oestrogen? Are they safe in menopause? Should women avoid soya — or actively include it?

In this episode, I explain what phytoestrogens actually are and how they work as selective oestrogen receptor modulators (SERMs). Rather than acting like strong hormones, they gently interact with your existing oestrogen receptors — and that distinction really matters.

We explore:

• The difference between "plant oestrogen" and SERM • The research on hot flush reduction • Food sources versus supplements

If you've felt confused by mixed messaging around soya, this episode will give you clarity and confidence.

As always, we're cutting through the noise to give you sensible advice, real food and genuine support.

A big thank you to our podcast sponsors, Revive Active. Their Revive Active Meno Active Complete contains a botanicals capsule providing standardised soya isoflavones, including genistein — one of the most researched phytoestrogens in relation to menopausal health. www.reviveactive.com

How fragrance, plug-ins and "clean smells" can affect hormones, sleep and your nervous system

In this final episode of the February toxin series, I'm exploring the impact of synthetic fragrance, plug-in air fresheners, scented candles, laundry boosters and perfumes. Many of these products release volatile organic compounds (VOCs) and fragrance blends that can act as endocrine disruptors and place extra demand on your liver and nervous system.

Unlike food, inhaled chemicals enter the bloodstream quickly and can influence the brain via the olfactory system. For many women, especially in mid-life, this can show up as headaches, sleep disturbance, brain fog or heightened sensitivity.

This isn't about stripping your home back to nothing. It's about understanding that "smells clean" doesn't always mean clean — and learning how to reduce background exposure in a realistic way.

In this episode we cover: • Why inhaled toxins can affect hormones and the nervous system • What's really in plug-in air fresheners and synthetic fragrance • Paraffin candles vs cleaner-burning alternatives • The connection between scent, cortisol and sleep • Simple swaps that create a calmer, less toxic home environment

Small reductions in daily exposure can give your body more capacity to regulate hormones, support sleep and maintain long-term health.

This episode wraps up our February series on reducing toxic load in a practical, achievable way — because your body already knows how to detox. Our job is simply to stop overwhelming it.

Your skin isn't just something you moisturise — it's an exposure route.

In this episode, I'm diving into the everyday products sitting in your bathroom and why they matter more than most of us realise. From deodorant and toothpaste to skincare and "fragrance", many of these products contain chemicals that can be absorbed through the skin and contribute to your overall toxic load.

Research suggests the average woman is exposed to well over 160 different chemicals every single day through personal care and cosmetic products. Individually, they may be present in small amounts — but it's the repeated, cumulative exposure that adds up.

Many of these compounds act as endocrine disruptors, meaning they can interfere with hormone signalling, liver detoxification and nervous system balance. In mid-life, when hormone shifts are already underway, reducing background exposure can make a meaningful difference.

In this episode we cover: • How chemicals are absorbed through the skin • Why cumulative exposure matters more than one "bad" product • The issue with "fragrance" and undisclosed ingredients • Deodorant vs antiperspirant — what's the difference? • Toothpaste, oral microbiome and gut health • Simple swaps that lower your daily chemical load without overwhelm

This isn't about perfection or throwing everything away. It's about awareness and making gradual changes that support your hormones, energy and long-term health.

This is part of the February toxin series — next week we finish by looking at the scents and air fresheners you're breathing in every day. Huge thanks to my podcast sponsors Revive Active for making clean supplements that I'm happy to recommend to clients, friends and family,

Your kitchen might look clean and organised, but there are hidden exposures in everyday habits that can quietly add to your hormonal load.

In this episode, I'm focusing on the toxins we don't usually think about — damaged non-stick pans, heating food in plastic, cling film, and everyday storage habits — and how heat can increase chemical transfer into food.

One of the biggest culprits? Plastic containers.

Many plastics contain compounds that can behave like oestrogen in the body. When they're scratched, discoloured or repeatedly heated, the risk of chemical leaching increases — especially into fatty or hot foods. Over time, that repeated low-dose exposure adds to the body's overall toxic burden.

This isn't about panic or perfection. It's about reducing background stress so your liver and hormones can do their job properly.

In this episode we cover: • Why heat + plastic increases chemical exposure • How endocrine disruptors can interfere with hormone balance • Why mid-life women are often more sensitive to background toxins • The problem with scratched non-stick pans • Simple, affordable swaps that make a genuine difference

Your action step this week is simple: Go through your cupboards and remove any damaged, scratched or discoloured plastic containers. If you wouldn't want to eat off it, it's time to replace it.

Small, steady changes like this can reduce toxic load and support energy, digestion and hormone balance in ways you might not expect.

This is part of the February toxin series — next week we move into bathroom and personal care products, and what your skin absorbs every single day.

We're told to eat "healthy", but food labels don't always tell the full story. Many everyday products that look virtuous on the front can still contain ingredients that quietly add to your toxic load - and in mid-life, that matters more than ever.

In this episode, I'm breaking down where food toxins are hiding, examples of what to look for, and how they can interfere with hormone balance, digestion and energy levels. Most importantly, I'll show you how to reduce exposure in a realistic way – without cooking everything from scratch or feeling overwhelmed.

This isn't about fear, perfection, or cutting everything out. It's about understanding what actually matters, so your body can focus on doing what it's meant to do.

In this episode we cover:

• Why food toxins affect hormones, digestion and energy

• How ingredient lists can be more important than front-of-pack claims

• The difference between ultra-processed foods and helpful convenience foods

• Common additives that increase liver and gut burden

• Why preservatives in packaged and sliced meats matter

• How batch cooking supports hormone health and saves money

• Practical high-street swaps that fit real life

Reducing toxic load is often one of the missing pieces when women feel tired, stuck or hormonally out of balance – even when they're "eating quite well".

🎧 This is the first episode in the February toxin series. Next week we'll move into kitchen toxins – the pans, plastics and storage habits you probably don't think twice about.

Shout out to our podcast sponsors - Revive Active. One of the reasons I'm so aligned with Revive Active is their focus on clean, well-formulated supplements. When we're talking about reducing toxic load, it's not just about food and the environment — it's also about being mindful of what we're taking in supplement form.

Their multivitamin complexes are designed to support the body without unnecessary fillers, artificial colours or additives, which is especially important when you're supporting liver function, hormones and overall resilience.

They have options that work really well for:

• Busy adults who want solid nutritional foundations

• Teenagers and older children who may have gaps in their diet

• Families who want one trusted brand rather than a cupboard full of different products

I often say to clients, a good quality multivitamin is like nutritional insurance — it doesn't replace good food, but it helps cover the basics, especially during busy or stressful periods.

High-intensity exercise is often promoted as the fastest way to burn fat and boost fitness. But many women find that doing too much HIIT leaves them exhausted, inflamed and struggling with stubborn belly fat.

In this episode, I explain why much of the exercise research behind HIIT has focused on male physiology, and how women's bodies respond differently to repeated high-intensity stress. We explore the role of cortisol, recovery and metabolic adaptation — and why pushing harder doesn't always lead to better results.

I also share how to build a more supportive movement routine that improves strength, energy and metabolic health without overwhelming your nervous system.

High-intensity exercise increases cortisol as part of the normal stress response. When training intensity is frequent and recovery is limited, cortisol can remain elevated. Research suggests chronically elevated cortisol may contribute to increased abdominal fat storage and reduced metabolic efficiency, particularly in women.

Very low-carb and keto-style diets are often praised for quick results, especially when it comes to fat loss. But many women find that what works brilliantly at first can later lead to fatigue, stubborn belly fat and a slowing metabolism.

In this episode, I explain why much of the research behind low-carb diets has focused on men, and how women's bodies respond differently to prolonged carbohydrate restriction. We explore how low energy availability can affect thyroid function, cortisol levels and metabolic rate — and why this often shows up as central weight gain rather than weight loss.

I also share a more balanced, hormone-supportive way of eating that supports energy, digestion and long-term metabolic health, without extremes.

Thank you to Revive Active for supporting this episode of the podcast. During periods of dietary change or restriction, I often recommend ensuring broad micronutrient support, particularly when energy levels feel low or recovery is slower than expected. There flagship produce - revive active, is perfect for anyone who wants to ensure their daily needs are met.

Carbohydrate intake influences thyroid hormone conversion, particularly the production of active thyroid hormone (T3), which plays a key role in metabolic rate and energy. Research suggests long-term very low-carbohydrate diets may reduce T3 levels and slow metabolism, particularly in women. Reduced metabolic output combined with elevated cortisol can contribute to stubborn abdominal fat storage.

Intermittent fasting is often promoted as a powerful health tool, but many women find that longer fasting windows leave them feeling tired, anxious or struggling with sleep.

In this episode, I explain why much of the fasting research has been carried out in men, and how women's hormones respond differently to prolonged periods without food. We look at cortisol, blood sugar balance and why daily long fasts can interfere with progesterone, oestrogen and thyroid health - particularly in mid-life.

I also share a more hormone-friendly way to approach fasting, so you can support metabolic health without pushing your body into stress mode.

Thank you to Revive Active for supporting this episode of the podcast. I often recommend Revive Active to clients during busy or demanding periods, as it provides broad micronutrient and amino acid support when nutrition or routine isn't quite optimal.

Research & further reading

Fasting places a metabolic stress on the body by signalling energy scarcity. Research suggests women are more sensitive to prolonged fasting than men, showing higher cortisol responses and changes to reproductive hormone signalling when fasting windows are extended. Shorter overnight fasts appear to support blood sugar balance and metabolic health without the same hormonal disruption.

Cold plunges and ice baths are everywhere right now - but what if they're leaving you feeling exhausted, wired or struggling to sleep?

In this episode, I explore why cold exposure can work well for men, yet backfire for many women. We look at how cold plunges affect cortisol, why female hormones respond differently to stress, and why too much cold can disrupt energy, mood and recovery — particularly in mid-life.

A more hormone-friendly approach for many women is cold-water swimming rather than ice baths. The water is usually slightly warmer, movement helps maintain circulation, and the gradual exposure avoids the shock response. The social and outdoor elements may also support nervous system regulation and mood.

If you've been pushing through ice baths because you think you should, this episode will help you rethink cold exposure in a calmer, more supportive way.

Research & further reading

Cold exposure activates the body's stress response, increasing adrenaline and cortisol. Research suggests women may experience a stronger and more prolonged cortisol response to cold stress than men, which can affect sleep, recovery and hormone balance if exposure is too intense or too frequent. Gentler cold exposure, such as cold-water swimming, appears to offer benefits for mood and stress regulation without the same physiological strain.
