What Is Magnesium — And Why Should You Care?

The essential mineral most of us aren't getting enough of

Magnesium-rich whole foods — nature's best sources of this vital mineral

You've probably heard of magnesium. It appears on supplement shelves, in wellness articles, and in conversations about sleep and stress. But what exactly is it — and why does your body need it so much?

Let us break it down for you.

 

What Is Magnesium?

Magnesium is an essential mineral that your body relies on to function properly. It supports healthy muscles, nerves, bones, and blood sugar levels — and plays a fundamental role in over 300 biochemical reactions taking place in your body every single day.

At a cellular level, magnesium is critical for:

•        Generating ATP — the energy currency of your cells

•        Repairing RNA and DNA

•        Promoting healthy nerve conductivity

•        Supporting the production of proteins and bone

 

It also has well-documented benefits for sleep quality, mood, exercise performance, and blood sugar regulation. In short — it's not a 'nice to have'. It's a non-negotiable for long-term health.

 

Magnesium works alongside calcium and Vitamin D3 to support strong, healthy bones

Signs You May Be Low in Magnesium

Magnesium deficiency is more common than many people realise — and the symptoms are easy to dismiss or attribute to other causes. If you experience any of the following, it may be worth paying attention:

•        Loss of appetite

•        Muscle cramps

•        Constipation

•        Irregular heartbeat (arrhythmia)

•        Weakness and fatigue

•        Headaches

•        Numbness and tingling

•        Tremors

•        High blood pressure

 

These symptoms can be subtle and develop gradually, which is exactly why magnesium deficiency often goes unrecognised for so long.

How Much Magnesium Do You Need?

Requirements vary depending on your age and life stage. The Recommended Dietary Intake (RDI)* is defined as the average daily intake sufficient to meet the nutrient requirements of 97–98% of healthy individuals.

 

*RDI = Recommended Dietary Intake  **Dependent on age

The Long-Term Consequences of Low Magnesium

This is where it gets serious. Chronic magnesium insufficiency — even at levels that don't cause obvious symptoms — can have significant implications for your long-term health. Complications that commonly go unrecognised include:

•        Altered glucose metabolism (which can lead to Type 2 Diabetes)

•        Metabolic syndrome

•        Hypertension

•        Atherosclerosis

•        Osteoporosis

•        Asthma

•        Migraines

•        Pre-eclampsia

•        Cardiovascular disease (CVD)

 

These aren't minor inconveniences. They are conditions that fundamentally affect quality of life — which is why ensuring adequate magnesium intake is so important, especially as we age.

Where Does Magnesium Come From?

Ideally, magnesium should come from your diet. Excellent food sources include:

•        Nuts and seeds (particularly pumpkin and sunflower seeds)

•        Leafy greens such as spinach

•        Avocado

•        Legumes

 

Realistically though, most people simply don't reach their RDI through food alone — whether due to busy lifestyles, soil depletion affecting nutrient content in produce, or dietary preferences.

Why We Developed Our Magnesium Lotion

Because we believe you shouldn't have to choose between what's good for you and what's easy to use, we developed our Magnesium Lotion as a smart, clean solution for topping up your magnesium levels.

 

Our lotion delivers magnesium transdermally — through the skin — which means it bypasses the digestive tract entirely. This is a real advantage over oral supplements, particularly for those with sensitive stomachs or absorption concerns.

 

Each 1ml of lotion contains 600mg of magnesium — though it's worth noting you're unlikely to absorb the full dose in a single application. It is, however, very well tolerated. In the rare event of too much magnesium being absorbed, your body will signal this clearly (think: loose stools) — and simply reducing your application will resolve it.

Benefits of Transdermal Magnesium

•        Supports better, deeper sleep

•        Helps relieve stress, tension, and muscle pain

•        Offers long-term protective benefits for heart health

•        A quick, easy solution for post-exercise muscle recovery

•        Suitable for children who struggle with tablets and aren't meeting their dietary requirements

 

Our Magnesium Lotion is super-hydrating, silky in texture, and genuinely a pleasure to use. Because at Intrinsic Skincare, we believe effective should never mean complicated.

Please note: If you are under the care of a doctor and taking medication, always consult your healthcare professional before introducing any supplement — including topically applied products.
