Advice & Health Tips
You can eat well.
You can do the workouts.
You can drink the water, take the walks, get to bed early and still feel like your body is not quite keeping up.
That is the thing about mineral depletion.
It does not always arrive loudly.
It can show up quietly, in the everyday signs we often explain away.
Tired again.
Foggy again.
Craving more coffee.
Waking in the night.
Catching everything going around.
It is easy to think you just need more discipline. More sleep. More willpower.
But sometimes, your body is not asking you to push harder.
It is asking you to rebuild the foundation.
Minerals such as magnesium, zinc, potassium, calcium and selenium help support energy, focus, hydration, muscle function, mood, sleep and immunity. When intake, absorption or retention falls short, the effects can be felt across the whole body. Magnesium deficiency, for example, is associated with fatigue, weakness, muscle cramps and changes in mood.¹
This is the mineral gap.
And these are seven signs your body may be feeling it.
1. You feel tired and low on energy
Tiredness is one of the easiest signs to ignore.
Because life is busy.
Because everyone is tired.
Because you got through the day anyway.
But persistent low energy can be a clue that your body is missing key nutrients involved in energy production, muscle function and nervous system support.
Magnesium plays a central role in normal energy metabolism, and early signs of magnesium deficiency can include fatigue and weakness.¹ This does not mean every tired day is mineral depletion.
But if your energy feels flat, even when you are doing “all the right things”, it may be time to look at the foundations.
2. You are struggling with brain fog
Brain fog can feel like walking through the day with the brightness turned down.
You are there.
You are functioning.
But focus takes more effort.
Minerals help support the brain and nervous system in several ways. Magnesium contributes to normal nervous system function, while zinc plays a role in normal cognitive function. Zinc deficiency has also been linked with cognitive symptoms such as problems with thinking, reasoning and memory.²
For women in midlife, brain fog is often blamed entirely on hormones or stress. Those can absolutely play a role.
But mineral status may be part of the picture too.
3. Your mood feels less steady
Mood changes do not always come from nowhere.
Minerals help support the nervous system, stress response and normal psychological function. Magnesium is particularly relevant because it is involved in hundreds of reactions in the body, including those linked to nerve and muscle function.¹
Research also describes a two-way relationship between magnesium and stress: stress may contribute to lower magnesium status, while low magnesium may make the body less resilient to stress.³
This matters because stress can be both a cause and a consequence of depletion.
The more pressure your body is under, the more support it may need.
The less support it gets, the harder that pressure can feel.
That is not weakness.
That is biology.
4. You are always thirsty
Constant thirst can have many causes and should not be ignored, especially if it is new, persistent or paired with frequent urination.
But minerals are part of the hydration story.
Electrolytes such as potassium, sodium, magnesium and calcium help regulate fluid balance, nerve signalling and muscle contraction.⁴ Potassium, in particular, is needed for normal kidney, heart, muscle and nerve function.⁵
Hydration is not just about water.
It is about water plus the minerals that help your body use it properly.
5. You get cramps, twitches or muscle tension
Cramps are one of the most recognisable signs people associate with minerals.
And for good reason.
Magnesium, calcium and potassium all help muscles contract and relax properly. Magnesium deficiency can cause muscle contractions and cramps, while potassium is essential for normal muscle contraction and nerve transmission.¹ ⁵
If you are waking with leg cramps, feeling more muscle tension than usual, or noticing twitches after exercise, your body may be signalling that mineral balance needs attention.
This can be especially relevant if you sweat regularly, drink alcohol, rely on caffeine, sleep poorly or are under ongoing stress.
Small daily drains can become a bigger shortfall over time.
6. You are having trouble sleeping
Poor sleep can feel like the problem.
But sometimes, it is also a symptom.
Magnesium has been widely studied for its role in sleep and relaxation. Research has linked magnesium intake with sleep quality and sleep duration, while newer reviews suggest magnesium status may influence sleep through its role in nervous system regulation and relaxation pathways.⁶ ⁷
Sleep is also when your body repairs, regulates and resets.
So when sleep is poor, the mineral gap can widen from both directions. You may feel more stressed, crave more caffeine, recover more slowly and place greater demand on the very nutrients your body is already struggling to maintain.
That is how the cycle builds.
Wired at night.
Tired in the morning.
Running on empty by 3pm.
7. You keep getting ill
If you feel like you catch every bug going around, your immune system may need more support.
Zinc and selenium are two of the best-known minerals for immune health. Zinc helps support normal immune function, while selenium contributes to the normal function of the immune system and helps protect cells from oxidative stress. Zinc deficiency is associated with impaired immune function and increased susceptibility to infections, while selenium plays an important role in immune response and antioxidant defence.² ⁸ ⁹
Again, this is not about one mineral doing one job.
It is about the body working as a system.
Energy, sleep, stress, hydration, muscles, immunity — they are connected. Minerals sit underneath all of them.
Why mineral depletion is so easy to miss
The signs of mineral depletion are often subtle.
They overlap with stress.
They overlap with hormones.
They overlap with poor sleep.
They overlap with modern life.
That is why the mineral gap can go unnoticed for so long.
You do not wake up one day suddenly depleted. It tends to build gradually through lower mineral intake, depleted soil and food quality, chronic stress, caffeine, alcohol, sweating, poor sleep, processed foods, age-related absorption changes and higher everyday demands.
And because the signs are so common, many people simply push through.
Until pushing through becomes the norm.
What to do if you think you are mineral depleted
Start with the basics.
Eat mineral-rich foods consistently: leafy greens, nuts, seeds, pulses, whole grains, quality protein, seafood, dairy or fortified alternatives.
Prioritise sleep where you can.
Watch the caffeine spiral.
Rehydrate properly.
Support stress recovery.
Consider whether targeted supplementation could help bridge the gap.
And if symptoms are persistent, severe or new, speak to a healthcare professional. Tiredness, thirst, brain fog, cramps, sleep disruption and frequent illness can have many causes, and it is important to get the right support.
The takeaway
Mineral depletion is not always dramatic.
Sometimes it looks like everyday life feeling harder than it should.
Less energy.
Less focus.
Less resilience.
Slower recovery.
Poorer sleep.
More frequent illness.
It is not always a lack of effort.
Sometimes, it is a weakened foundation.
And once you understand the signs, you can start giving your body what it needs to rebuild.

We live in a world that is faster, more demanding, and constantly “on.” Yet beneath the surface, something more fundamental is happening: the essential minerals our bodies rely on are being steadily depleted - creating what we call a mineral gap.
This gap isn’t always obvious, but it’s increasingly common.
Most people don’t notice it happening.
They just feel the effects.
Energy drops.
Focus fades.
Recovery slows.
It’s not a lack of effort.
It’s a weakened foundation.
Once you understand what’s driving the mineral gap, you can start rebuilding the foundation your body relies on.
What are minerals, and why do they matter?
Minerals are essential nutrients your body cannot make on its own. You have to get them from food, drink or supplementation.
They may be small, but their role is anything but.
Magnesium supports energy production, muscle function and the nervous system. Calcium contributes to bones and muscle function. Zinc supports immunity, skin and normal cognitive function. Selenium helps protect cells from oxidative stress. Potassium supports fluid balance and normal muscle function.
In other words, minerals are not “nice to have.” They are foundational.
They help your body do the things you expect it to do every day: wake up with energy, think clearly, move well, recover properly, sleep deeply and stay resilient.
When intake, absorption or retention starts to fall short, the effects can be subtle at first.
A little more tired.
A little more wired.
A little slower to bounce back.
Over time, those small shifts can add up.
DID YOU KNOW
Mineral levels of zinc, iron, copper and magnesium in wheat have declined by an estimated 20–30% since the mid-1960s.¹
1. Our soil is not as mineral-rich as it used to be
Minerals begin in the soil.
Plants absorb minerals as they grow. We eat the plants - or animals that have eaten the plants - and those minerals become part of our own nutritional intake.
So when soil quality changes, food quality can change too.
Modern farming has helped feed a growing population, but it has also placed enormous pressure on soil health. Intensive cultivation, reduced crop diversity, soil erosion, lower organic matter and repeated harvesting can all affect the mineral profile of the food grown in that soil.
The Soil Association has highlighted the need to rebuild soil organic matter, reduce over-cultivation and protect soil life as part of maintaining healthier, more resilient soils.²
Long-running research from Rothamsted’s Broadbalk Wheat Experiment found that levels of zinc, iron, copper and magnesium in wheat stayed relatively stable from 1845 until the mid-1960s. After that, they declined significantly, with an overall reduction of around 20–30%.¹
That matters.
Not because vegetables are suddenly “bad” for us. They are not. Whole foods still matter hugely.
But it does mean the same plate of food may not always deliver the same mineral density it once did.
So you can be eating well - and still not getting quite what your body needs.
2. Stress burns through your mineral reserves
Stress is often treated like a mindset issue.
But your body experiences it physically.
When you are under pressure, your body shifts into a higher-demand state. Your nervous system works harder. Your muscles tense. Your heart rate changes. Your sleep can suffer. Your body has to produce and regulate stress hormones.
All of that requires nutrients.
Research suggests that psychological and environmental stress can affect levels of key micronutrients, including magnesium, zinc, calcium and iron.³ Magnesium is particularly important because of its role in the nervous system and stress response.
This is where the cycle can begin.
Stress can contribute to lower magnesium status. Lower magnesium status can make it harder for the body to manage stress well. Researchers have described this as a two-way relationship between magnesium and stress.⁴
And for many women in midlife, stress is not occasional.
It is constant.
Work. Family. Hormonal change. Poor sleep. Caring responsibilities. Mental load. Life admin. The pressure to keep functioning at full speed.
The body keeps going.
But it still needs support.
3. Age changes how we absorb and use minerals
From around midlife, the body starts to change in ways that can affect mineral status.
This is not about “getting old.” It is biology.
Research shows that ageing can affect intestinal absorption of key minerals, including calcium, zinc and magnesium.⁵ Magnesium status may also become more vulnerable with age, due to lower intake, reduced absorption and increased loss through the kidneys.⁶
For women, this becomes especially relevant from the 40s onwards.
Hormonal changes can influence sleep, stress resilience, muscle function, bone health and energy metabolism - all areas where minerals play a key supporting role.
Calcium is a good example. Absorption can decline with age and post-menopause, which matters for long-term bone and muscle health.⁷
DID YOU KNOW
Calcium absorption has been reported to decline by around 0.21% per year after age 40.⁷
Again, this does not mean deficiency is inevitable.
It means the foundation needs more attention.
What worked in your 20s or 30s may not be enough in your 40s, 50s and beyond. Your body may need more consistency, more nutrient density and more targeted support.
4. Caffeine, alcohol and poor sleep widen the gap
The mineral gap is rarely caused by one thing.
It is usually the result of lots of small daily drains.
Caffeine can increase fluid output in some people, and for many of us it becomes a crutch when sleep is poor. Alcohol can affect magnesium status and increase urinary losses. Processed foods can crowd out more nutrient-dense choices. Poor sleep can raise stress levels, which can then increase the body’s demand for minerals involved in energy, recovery and nervous system balance.
It becomes a loop.
Poor sleep leads to more caffeine.
More caffeine can affect hydration.
Stress builds.
Recovery slows.
Energy drops.
The body asks for more support - but often receives less.
This is why mineral support is not just about what you eat.
It is also about what modern life asks from you.
5. Modern diets can be full, but not fully nourishing
Many people are not underfed.
They are undernourished.
A modern diet can provide enough calories while still falling short on key minerals. This can happen when meals are built around ultra-processed foods, low-protein choices, skipped meals, restrictive dieting or a lack of variety.
Even “healthy” diets can miss the mark if they are repetitive, low in mineral-rich foods or not matched to your stage of life.
The goal is not perfection.
It is consistency.
Leafy greens, nuts, seeds, pulses, whole grains, seafood, quality protein, dairy or fortified alternatives can all help provide essential minerals.
But for many women over 45, food alone may not always bridge the gap - especially when stress, poor sleep, age-related changes and modern soil quality are all working in the opposite direction.
This is where thoughtful supplementation can play a role.
Not as a replacement for a good diet.
As a daily reinforcement.
The mineral gap is quiet - until it isn’t
You may not feel mineral depletion happening in real time.
You may just notice that you are not recovering like you used to.
That your energy feels less steady.
That your focus dips earlier in the day.
That sleep feels lighter.
That your muscles feel tighter.
That stress feels harder to shake.
These signs can have many causes, and persistent symptoms should always be discussed with a healthcare professional.
But the foundation is worth looking at.
Because minerals support the systems that keep you functioning well every day.
Energy.
Hydration.
Muscle function.
Nervous system balance.
Bones.
Sleep.
Resilience.
The mineral gap is not about doing more.
It is about giving your body more of what it needs to keep up with the life you are already living.

By midlife, many people feel they’re doing the right things - eating reasonably well, staying active, trying to manage stress - yet still notice lower energy, slower recovery, or a sense that their body isn’t responding in the same way it used to.
While protein and fibre often dominate the conversation, minerals are fundamental to how the body functions. As we age, changes in intake, absorption, lifestyle and physiology can make consistently lower mineral status more noticeable.
Understanding why mineral levels are so important with age - and how to support them - can help you restore the nutritional foundations that keep energy, resilience and long-term health on track.
What Are Minerals and Why Are They So Important?
Minerals are essential nutrients. Unlike many other compounds in the body, we cannot make them ourselves - we rely entirely on dietary intake and effective absorption.
The role minerals play in energy, immunity, bones and hormones
Minerals are involved in:
- Energy production and metabolism
- Muscle contraction and nerve signalling
- Immune function
- Thyroid activity
- Antioxidant protection
- Bone structure and maintenance
These systems become increasingly important in midlife, when resilience may naturally decline.
Why minerals are the foundation of good health
Minerals are both structural and functional. They form the building blocks of bones and teeth, but they also enable enzymes to work, muscles to contract and nerves to communicate.
Without adequate mineral status, many core body systems simply cannot operate efficiently. In this sense, minerals truly form part of the body’s nutritional foundations.
How Ageing Changes the Way Your Body Uses Minerals
Reduced absorption in the gut
One of the most overlooked factors in midlife nutrition is absorption. As we age, digestive efficiency can decline, meaning we may not extract or absorb minerals as effectively as we once did.
Changes in stomach acid and digestive enzymes
Stomach acid plays a crucial role in releasing minerals from food and converting them into absorbable forms. Lower stomach acid - which becomes more common with age - can reduce mineral availability.
Simple habits such as slowing down at meals, chewing thoroughly, and eating in a calmer state can support digestion and improve nutrient utilisation.
Age-related shifts in metabolism and storage
Ageing can also affect how nutrients are transported, stored and used in the body. At the same time, long-term stress, busy lifestyles and irregular eating patterns can increase the body’s demand for certain minerals.
Modern Life: Why Mineral Depletion Is More Common Than Ever
Soil depletion and declining mineral content of food
There is ongoing discussion around whether modern agricultural practices have reduced the mineral density of soil and food. While debate continues, there is evidence suggesting that some foods may contain lower mineral levels than in the past.
Ultra-processed diets and lower nutrient density
More significantly, modern diets often rely heavily on ultra-processed foods. These tend to be lower in naturally occurring minerals compared with whole foods such as vegetables, legumes, nuts, seeds and whole grains.
Food quality and variety matter more than ever in midlife.
Stress and its impact on mineral loss
Chronic stress - whether from demanding careers, family responsibilities or irregular eating - places additional strain on the body. Ongoing stress may increase the body’s need for certain minerals, particularly magnesium.
Supporting mineral status is therefore not just about intake, but also about lifestyle balance.
Reduced appetite and lower food intake with age
Some individuals simply eat less as they age. Reduced food intake can unintentionally lower mineral consumption, especially if dietary variety is limited.
Must-have Midlife Minerals
Individual needs vary, but several minerals frequently stand out in midlife nutrition.
Magnesium – for energy, muscles and nerves
Magnesium is involved in over 300 enzymatic reactions. It contributes to:
- Energy-yielding metabolism
- Normal muscle and nerve function
- Reduction of tiredness and fatigue
Midlife is often characterised by demanding careers, family responsibilities, and long-term stress. Ongoing stress can increase the body’s demand for magnesium, while dietary intake is frequently lower than ideal. For this reason, magnesium intake is a key consideration for many people looking to support energy levels and overall resilience during this stage of life.
Zinc – for immunity and repair
Zinc supports immune function, digestion and metabolic processes. It also plays a role in maintaining stomach acid production, which further influences mineral absorption.
Selenium – antioxidant, immunity and thyroid support
Selenium is required in relatively small amounts, but intake can be low in European diets. It contributes to normal thyroid function, immune defence and antioxidant protection - all increasingly relevant in midlife.
Calcium – bone health in midlife
Calcium contributes to the maintenance of normal bones. This becomes particularly important for women after menopause, when bone turnover accelerates due to hormonal changes.
These minerals work together as part of a broader nutritional network, rather than in isolation.
Why Men and Women Have Different Mineral Needs
Hormonal changes influence how the body responds to ageing. Women experience a more abrupt hormonal shift around menopause, while men tend to experience more gradual changes over time.
These hormonal changes are associated with shifts in bone turnover, which is why nutrients such as calcium and magnesium, alongside vitamins D3 and K2 and regular weight-bearing exercise, are an important part of supporting bone health as we age.
Can You Get Enough Minerals from Diet Alone as You Age?
For most people, progress starts with the fundamentals:
- A varied, Mediterranean-style eating pattern
- Plenty of colourful vegetables, fruits, legumes, nuts, seeds, and whole grains
- Adequate protein across meals
- Eating in a way that supports digestion rather than undermines it
These habits provide a strong nutritional foundation and mineral intake through midlife and beyond.
However, in practice - busy lifestyles, dietary limitations and digestive changes can make consistent optimal mineral intake more challenging.
Supporting Your Body’s Mineral Foundations After 50
Choosing targeted, well-absorbed mineral support
When supplements are used, they work best as part of a wider nutritional strategy:
- Moderate doses rather than extremes
- Nutrients in forms the body can readily use
- Broad-spectrum formulations rather than isolated “quick fixes”
Minerals such as magnesium, zinc, and selenium are commonly included within this approach.
Why a balanced multinutrient, such as Wassen Prime Protect 50+, can support mineral levels as you age
Both Prime Protect 50+ Men and Prime Protect 50+ Women are designed to provide comprehensive, balanced support in just one daily capsule.
Each formula contains a broad spectrum of essential vitamins, minerals and antioxidants - including magnesium, zinc, selenium and B-vitamins - to support energy metabolism, immune function, muscle health and protection against oxidative stress.
Importantly, the formulas are tailored specifically for men and women over 50, recognising that nutritional needs shift with age and hormonal changes.
- Prime Protect 50+ Men includes targeted nutrients such as zinc to support testosterone balance, alongside magnesium for muscle and bone health and antioxidant nutrients to help protect cells from everyday stress.
- Prime Protect 50+ Women provides core mineral support alongside botanicals traditionally associated with women’s health, including sage and ashwagandha, with particular focus on energy, cognitive clarity, bone maintenance and overall resilience during and after menopause.
Both formulas use nutrients in bioavailable forms, meaning they are provided in forms the body can readily recognise and absorb.
Rather than megadosing individual nutrients, the focus is on delivering balanced, foundational support - helping to bridge potential nutritional gaps and restore the mineral foundations that modern life can quietly deplete.
Key Takeaway: Restoring the Foundations for Healthy Ageing
Ageing does not automatically mean deficiency. However, midlife is often the stage where small, cumulative nutritional gaps become more noticeable.
Focusing on:
- A varied, whole-food-based diet
- Mindful eating to support digestion
- Stress management
- Regular movement and strength training
- Strategic, balanced supplementation where appropriate
can help restore and maintain the mineral foundations that modern life may quietly deplete.

When coughs and colds start doing the rounds at school, or winter bugs seem harder to shake than they once were, it’s natural to think more carefully about immunity. A busy lifestyle, changing seasons and getting older can all place extra demands on the immune system. Supporting your body with the right immunity vitamins and minerals can help keep your natural defences working effectively - helping you stay well all year round.
Each of the vitamins and minerals below plays a slightly different role, but together they help support a balanced, effective immune response.
“Nutrients such as Selenium, Zinc and Vitamins A, C, E and D are especially important for immunity because they support immune cell function, antioxidant protection and immune regulation.”
- Vicky, Wassen Nutritionist
The key vitamins and minerals your body needs for immunity
Selenium – protecting immune cells from oxidative stress
Selenium is a vital trace mineral that contributes to the normal function of the immune system and helps keep immune cells working as they should.
Inside the body, selenium is used to form proteins known as selenoproteins, which help regulate immune and inflammatory responses.[1] These proteins also protect immune cells from oxidative stress caused by free radicals - something that naturally increases when your immune system is fighting off infections. This protective role helps immune cells stay effective during times of increased demand.
Good food sources of selenium include:
Brazil nuts, fish, seafood, eggs and wholegrains.
Zinc – essential for immune response and cell development
Zinc is essential for a healthy immune response and helps the body react effectively when it encounters germs.
It supports the development and communication of immune cells that are central to immune defence. Zinc also helps maintain physical barriers such as the skin, which act as the body’s first line of protection against pathogens.[2]
Good food sources of zinc include:
Shellfish, red meat, pumpkin seeds, nuts, seeds and wholegrains.
Vitamin A – supporting the body’s first line of defence
Vitamin A plays an important role in maintaining healthy skin and mucous membranes, which form the body’s first barrier against germs entering the body.
It also supports immune cells involved in recognising and responding to infections, helping the immune system react efficiently when challenged.[3] This makes vitamin A especially important for maintaining everyday immune resilience.
Good food sources of vitamin A include:
Carrots, sweet potatoes, spinach, kale and liver.
Vitamin C – supporting immune cell activity
Vitamin C is one of the most well-known immunity vitamins and supports several aspects of immune function.
It is needed for the production and activity of white blood cells, which help the body defend against bacteria, viruses and other pathogens. Vitamin C also supports immune cell activity and helps protect immune cells from oxidative stress.[4]
In addition, vitamin C contributes to reduced tiredness and fatigue - which can be particularly helpful when your immune system is working hard.
Good food sources of vitamin C include:
Citrus fruits, strawberries, kiwi, peppers and broccoli.
Vitamin E – antioxidant support for immune health
Vitamin E helps protect cells from oxidative stress, which can increase when the immune system is active.
By helping to neutralise free radicals, vitamin E supports the normal function of immune cells. It also plays a role in communication between immune cells, which is essential for an effective immune response.
Good food sources of vitamin E include:
Almonds, sunflower seeds and hazelnuts.
Vitamin D – regulating immune function
Vitamin D contributes to the normal function of the immune system by supporting immune cell regulation and activation.[6]
Low vitamin D levels are common in the UK, particularly during autumn and winter when sunlight exposure is limited. For this reason, vitamin D is one of the most important immunity vitamins to consider during the colder months. The NHS advises supplementing with 10μg of vitamin D per day during winter.[7]
Good food sources of vitamin D include:
Oily fish, egg yolks, fortified foods and sunlight exposure.
Why a combined approach to immunity matters
The immune system is extremely complex and relies on many nutrients working together. Selenium and zinc support immune cell function, while vitamins A, C, E and D contribute to immune defence and antioxidant protection. This combined approach is often more effective than focusing on a single nutrient alone, especially when life or diet makes consistency difficult.
Supporting immunity with an immune boosting supplement
Even with a balanced diet, it can be difficult to meet optimal intake levels of all key immune boosting vitamins and minerals every day. A well-formulated immunity supplement can offer extra support, particularly during busy periods and the winter months.
Wassen Selenium ACE+D brings together selenium, zinc and vitamins A, C, E and D in one carefully balanced formula to support immune function and antioxidant protection. It's a simple, convenient and science-backed way to support your daily immune health.
