Why We Spray Magnesium on Our Feet (and Why It Actually Works)

Let’s talk about something that might sound a little strange at first—spraying magnesium on your feet. Yes, your feet. Those two solid, silent companions that hold you up, carry you through the world, and (let’s be honest) are often the last to receive any love.

At SISUU, we’ve spent time steeped in both science and ancient wisdom to understand why this simple ritual of applying magnesium spray to your soles can make such a difference. It’s not just folk medicine or placebo. There’s good reason behind it, and it’s become one of our favourite ways to unwind, reset, and re-mineralise—especially with our SISUU Magnesium Recovery Spray.

WHY THE FEET

The skin on your feet is actually one of the most absorbent parts of your body, especially the soles. There are more than 200,000 nerve endings in each foot (wild, right?), along with large pores and relatively thin skin compared to other areas. This makes it a great entry point for minerals like magnesium to work their magic.

In traditional Eastern medicine, the feet are more than just the end of the body—they’re deeply connected to energy meridians and organ systems. Think of them like a map of the body. Stimulating the soles can help bring balance, calm, and a feeling of groundedness. No wonder foot soaks, massages, and acupressure have been part of healing traditions for centuries.

So when you spray magnesium on your feet, you’re tapping into both old-world healing and modern bioavailability.

WHAT DOES THE SCIENCE SAY?

The Western world is slowly catching up. Some studies have shown that transdermal (through the skin) application of magnesium can increase cellular magnesium levels. The skin acts as a semi-permeable barrier, meaning that with the right form—like magnesium chloride, the type we use in our SISUU spray—absorption is possible, especially through the hair follicles and sweat glands.

That said, the research is still evolving. But what we do know is that topical magnesium avoids the digestive system, making it gentler on the gut and a great option for people who find oral supplements upsetting. Anecdotally, thousands of people swear by it, especially for soothing sore muscles, calming nerves, and improving sleep.

HOW WE USE OUR MAGNESIUM SPRAY?

Here’s the ritual we come back to, time and time again:

• Night-time wind-down: After a long day, spray 4–5 sprays of SISUU Magnesium onto the soles of your feet. Massage it in gently, breathe deeply, and let it soak in.

• Pair with our favourite wind down music: A few deep belly breaths or legs-up-the-wall pose while the spray dries. Tunes on. No rush. No scrolling.You might feel a slight tingling—especially if your body’s running a little low in magnesium. That’s normal. We've added aloe vera to our spray to soften that sensation and help your skin drink it in more gently.

• Got a cramp or ache? You can also spray directly onto a muscle that’s cramping or a limb experiencing growing pains. Yes our spray is pregnancy and children safe. 

WHEN IS THE BEST TIME?

We love it before bed. Magnesium supports nervous system regulation and the production of melatonin, your body’s natural sleep hormone. It also helps release tension from muscles after a big day (or workout, or wine night, no judgment). But honestly, you can use it any time you need to shift gears—whether it’s calming morning nerves or centring yourself mid-afternoon.
