What is Magnesium and Why is it Important? 

Magnesium supports over 300 biochemical processes in the body. It’s essential for:

• Muscle repair and relaxation

• Stress regulation

• Sleep quality

• Hormonal balance

• Steady energy production

When we skip recovery, we burn out faster. When we ignore stress, our performance drops. Magnesium works quietly in the background to restore what stress, exercise and modern life take away.

We used to get all of our magnesium from the foods we ate, but as farming practices and diet have changed, most are not able to get their daily magnesium from the modern diet alone.  

Why Everyone’s Talking About Magnesium Spray

If you’ve heard about magnesium spray but still have questions like “Where do I spray it?” or “How much should I use?”, you’re not alone.

Topical magnesium also called magnesium oil spray has become a favourite among wellness seekers for its ease of use, fast absorption, and wide-ranging benefits.

At Salt Lab, we’ve perfected the formula with our Bestselling Magnesium Oil Spray, helping thousands of people improve their sleep, mood, recovery and resilience to stress.

This guide answers your most frequently searched questions and shows you how to create your own magnesium ritual, starting with a few simple sprays.

What Does Magnesium Spray Do?

When you apply magnesium transdermally (through the skin), your body absorbs it directly into the bloodstream, bypassing digestion, which can often limit absorption in pill form.

This makes it a great option for people with gut sensitivities, kids, athletes, or anyone wanting a natural alternative. It can also be used in conjunction with a magnesium supplement to help increase overall magnesium through the day and in the moments it needs it most such as after the gym, during the busy school pick up or even before bed to help signal the body to wind down.  

Where to Spray Magnesium Oil for Sleep and More

One of the most commonly asked questions is: “Where should I spray magnesium oil for sleep?”

While you can use magnesium spray on most parts of your body, these areas are especially effective:

• Feet: The soles of your feet have large pores and fewer oil glands, making them ideal for quick, deep absorption. This area is especially useful before bed or for calming anxious children.

• Stomach: Great for systemic absorption and calming the nervous system.

• Back of neck and shoulders: Target areas for muscle tension and stress relief.

• Legs and arms: Ideal after workouts or for full-body support.

• Temples or wrists: For targeted relief during high-stress moments (use our Magnesium Roll-On for this).

For kids, we recommend applying magnesium spray on feet only, especially before bedtime.

How Much Magnesium Oil to Use (and Can You Use Too Much?)

How many sprays of magnesium on feet?

Start with 4-6 sprays per foot, ideally before bed. Gently massage it in for 30 seconds and allow it to absorb.

How often should I use magnesium spray?

Daily use is best. You can use magnesium spray once or twice a day depending on your needs - morning for calm energy, evening for sleep support, and post-workout for recovery.

How many times a day can you use magnesium spray?

Up to 3 times daily is safe for most people. Always listen to your body and adjust as needed.

Can you use too much magnesium spray?

It’s hard to overdo it, as your body will naturally excrete what it doesn’t need. However, if you're new to magnesium spray, start slowly and build up. If you notice skin irritation, reduce the number of sprays or dilute with a natural body lotion. 

What Does It Feel Like? Does Magnesium Oil Sting?

Some users experience a mild tingling or stinging sensation when first using magnesium spray, especially if they are low in magnesium or apply it to sensitive skin.

This feeling is normal and usually fades over time as magnesium levels are replenished. If it’s uncomfortable, apply over moisturised skin or try the feet first where the skin is thicker.

Can You Use Magnesium Spray When Pregnant or on Kids?

Can you use magnesium spray when pregnant?

Yes, with your doctor’s approval. Many women use magnesium spray during pregnancy to manage cramps, sleep issues and stress. It’s a gentler alternative to tablets, especially if you’re experiencing nausea or digestive discomfort.

Can you use magnesium spray on kids?

Absolutely. Our Kids Magnesium Spray is  specifically designed for gentle, kid-safe use. Always patch test and apply to feet only for little ones. Our Family Routine bundle is a great option for those after magnesium for the whole family.
