Not All Magnesium Is Created Equal

Science Week Spotlight: Let’s Get Real About Magnesium

It’s National Science Week, and we’re cutting through the noise with one key message: not all magnesium is created equal.

Yes, magnesium is essential. But the type of magnesium you choose and how you absorb it matters far more than the label on the bottle or the price tag.

Cheap, low-quality supplements may look good on the shelf, but they often deliver little to no benefit. To truly support your energy, sleep, recovery and mood, you need to understand the science behind magnesium delivery.

Magnesium Types 101: What’s the Difference?

Magnesium isn’t a one-size-fits-all mineral. There are multiple types, each with different bioavailability and effects on the body.

Here’s a breakdown of the most common forms:

  • Magnesium Oxide: Inexpensive and widely available, but absorbed at only around 4%. Commonly used in laxatives. Not ideal for replenishment.

  • Magnesium Citrate: Offers better absorption than oxide and helps with constipation. May cause digestive upset in some users.

  • Magnesium Glycinate: Known for calming effects and being gentle on the stomach. A good option for stress and sleep.

  • Magnesium Chloride: Highly bioavailable, especially when used topically. Ideal for fast absorption and effective magnesium replenishment.

  • Magnesium Sulfate: Also known as Epsom salts. Effective for occasional soaks, but not reliable for regular magnesium intake.

Absorption Beats Dosage

Here’s the truth: you could take 500 mg of magnesium, but if your body only absorbs 4%, the actual benefit is negligible.

Take magnesium oxide for example. It’s often listed in high doses but delivers very little usable magnesium to your cells. On the other hand, magnesium chloride is readily absorbed and utilised by your body quickly, especially when applied directly to the skin.

When it comes to supplementation, bioavailability matters more than quantity.

Why Topical Magnesium Comes Out on Top

Unlike tablets or powders, topical magnesium avoids the digestive system completely. That means:

  • No bloating or upset stomach

  • No unnecessary fillers

  • Faster absorption

  • Better utilisation by muscles and nerves

Our Magnesium Oil is applied directly to the skin and absorbed into your bloodstream, where it can begin working immediately. It’s a smart, science-backed way to get the benefits of magnesium without the side effects.

The Problem With Cheap Magnesium

We get it. Saving money feels good but when it comes to your health, cheap magnesium can cost you more in the long run.

Low-quality supplements often:

  • Contain poorly absorbed forms (like magnesium oxide)

  • Include unnecessary binders, colours or fillers

  • Cause bloating, diarrhoea or cramping

  • Provide minimal improvement in symptoms

If you’re not feeling the difference, your body likely isn’t absorbing it. Quality and form are everything.

Why Salt Lab’s Magnesium Is Different

At Salt Lab, we use 100% natural magnesium chloride sustainably sourced from the Tibetan Plateau, one of the purest sources in the world.

  • Is non-toxic, gentle and clean

  • Contains no fillers or synthetic additives

  • Offers maximum bioavailability through topical use

  • Is backed by scientific research, not wellness trends

Science-Driven Wellness Starts Here

We believe that knowledge is power, especially when it comes to health and supplementation. National Science Week is the perfect reminder to question what’s in your wellness routine, and to prioritise evidence over hype.

When you understand how different magnesium types work and why absorption matters, you can make better choices for your energy, mood, recovery and sleep.

Let’s Ditch the Myths, Not the Magnesium

Choosing the right magnesium isn’t about trends or savings, it’s about results. When you want a supplement that actually works, look at the science, not just the price tag.

Try magnesium that’s made for performance, not profit.
