6 ways to boost your mineral intake (that don't include food)
Think nutrition only happens at the dinner table? Think again.
We've all been there, staring at our supplement cabinet, wondering if we're really getting enough magnesium, or scrolling through endless lists of synthetic supplements that promise to fix our mineral deficiencies. But here's something that might surprise you... your body can actually absorb nutrients in ways you've probably never realised.
Your skin, your lungs, even the soles of your feet, they're all secretly working as nutrient gateways. And in some cases, these alternative pathways can be even more effective than supplements or forcing down another green smoothie.
Ready to discover the world of non-dietary nutrition? Let's dive in.
1. Sunbathing
Remember when your grandmother used to say "go get some sun"? Turns out, she was onto something. When UVB rays hit your skin, they trigger an almost magical transformation, converting 7-dehydrocholesterol (a compound naturally present in your skin) into vitamin D3.
This isn't just about avoiding seasonal blues. Vitamin D orchestrates calcium absorption, fine-tunes your immune system, regulates hormones, and keeps your muscles functioning properly.
The catch? Without adequate sun exposure, especially during winter months or if you live at higher latitudes, your body simply can't make this happen on its own. Vitamin D deficiency is linked to all sorts of health issues, so getting enough sun exposure in a sensible way will be helping your body immensely, after all why do you think your cat or dog loves to lay in those sun patches?... they are onto something.
So that midday break in the garden isn't just for relaxation, it's helping your health more than you realise.
2. Swimming in the sea
Sea swimming does more than just make you feel refreshed and salty. That seawater enveloping your body contains a complex cocktail of minerals that can actually penetrate your skin, especially during longer swims in warmer water.
We're talking about magnesium for muscle relaxation, sodium for electrolyte balance, calcium for bone and nerve function, potassium for heart rhythm regulation, and iodine to support thyroid health. Even trace amounts of zinc and selenium make their way through, offering antioxidant and immune support.
In Greece, doctors (especially in coastal towns and islands) sometimes write prescriptions for thalassotherapy, which includes swimming in the sea, exposure to sea air, and sometimes walking along the beach, particularly for joint problems, skin conditions, and recovery after illness. It’s rooted in both ancient Greek medicine (Hippocrates recommended seawater baths) and modern practice.
3. Epsom bath salts/magnesium spray
Here's where things get interesting from a bioavailability standpoint. That warm Epsom salt bath you take to unwind? It's delivering magnesium directly through your skin, bypassing your digestive system entirely. This method is actually more bioavailable than trying to get magnesium from dietary or supplement sources. As well as being a much better option of absorption for the many people who struggle to absorb magnesium orally due to gut issues such as leaky gut.
Epsom salts provide both magnesium (supporting over 300 enzymatic reactions in your body) and sulphur (crucial for detoxification and collagen production). Meanwhile, magnesium chloride sprays take things up a notch, their more targeted approach penetrates skin more efficiently, often creating that characteristic tingly sensation as it interacts with your nerve endings, which is a sign you are deficient in magnesium!
4. Grounding
This might sound far fetched, but the science is surprisingly solid. The Earth's surface carries a negative electric charge, and when your bare skin makes contact with grass, soil, sand, or seawater, electrons can actually transfer into your body.
These electrons act as natural antioxidants, neutralising free radicals and potentially reducing inflammation. It's essentially nature's way of helping you reset at the cellular level, no meditation app required.
If you've ever had a stressful day and then taken to the garden with your shoes and socks off you probably noticed how calming it feels to finally ground.
We are always looking for ways to get more antioxidants into our body through food which are important but we should also look to grounding which one of the best antioxidant you can “take”
5. Mineral hot springs
Humans have been seeking out hot springs for millennia, and our ancestors were onto something. These geological wonders are like concentrated mineral delivery systems, with your skin absorbing magnesium for muscle relaxation, calcium for bone health, sodium and potassium for electrolyte balance, and sulphur for joint support and collagen production.
The heat opens your pores, the minerals do their work, and you emerge feeling like you've been internally recharged.
6. Herbal oil steam inhalation
While primarily known for respiratory benefits, steam inhalation from mineral-rich herbal preparations can deliver trace amounts of minerals through your lungs. Though the quantities are minimal, it's yet another example of how your body finds creative ways to absorb what it needs.
What's fascinating about all these methods is how they bypass common absorption issues that plague oral supplementation, no stomach upset, no competition with other nutrients, no concerns about digestive efficiency.
Your body is remarkably sophisticated at finding and utilising nutrients from unexpected sources. So the next time you're planning your wellness routine, remember... sometimes the most powerful nutrition can come from practices you do rather than what you eat.
Ready to expand your nutrient absorption toolkit? Start with just one of these methods and notice how your body responds. After all, the best supplement might just be stepping outside barefoot or soaking in a warm bath.
