Homemade Magnesium Oil

Easy to mix magnesium oil spray to use topically for enjoyment of the transdermal effects of magnesium for pennies per spray.

Transdermal magnesium is a great way to enjoy the benefits of this anti-inflammatory, calming nutrient.

While my favorite topical is this recipe for homemade magnesium lotion, I’ve also received several requests for a spray form that is quicker to blend.

In those situations where you wish to enjoy the benefits of absorbing magnesium via the skin but do not want to make lotion, I would suggest homemade magnesium oil.

Magnesium Chloride vs Epsom Salt

You can make this type of magnesium spray using magnesium chloride salt or Epsom salt (magnesium sulfate).

Which type of magnesium salt to choose?

The answer to that depends on your skin sensitivity.

Magnesium chloride salt has more magnesium in it and so will make a more potent transdermal spray.

If you’ve tried commercial magnesium oil before and know that it makes your skin itch or burn a bit, then I recommend using Epsom salt instead.

You can also use a mix of the two salts (they do not interact with each other when dissolved in water), to add the benefits of the sulfur in Epsom salt to your homemade topical spray.

Note that Espom salt can be a bit itchy too if you get too much on your skin.

With this DIY recipe below, your primary task is to find which magnesium salt (or a mix of the two) is the perfect blend for you as the preparation itself only takes a few minutes!

Here’s how much elemental magnesium is in 1 mL (about 6 sprays), depending on the blend of magnesium salts you choose to use….

Magnesium Chloride Spray

1/2 cup magnesium chloride salt (blended with 1 cup of water): 94 mg elemental magnesium per 1 mL (6 sprays)

*Note that if you use magnesium chloride flakes instead of magnesium chloride salt, the amount of elemental magnesium in 1 mL will be roughly half as potent (48 mg elemental magnesium) due to the lower density of the flakes.

Epsom Salt/Magnesium Chloride Spray

1/4 cup magnesium chloride and 1/4 cup Epsom salt blended with one cup of water will yield a magnesium oil that contains about 83 mg of elemental magnesium per 1 mL (6 sprays).

Magnesium Sulfate (Epsom Salt) Spray

If you use 1/2 cup Epsom salt blended with one cup of water, the resulting magnesium oil contains roughly 88 mg of elemental magnesium per 1 mL (6 sprays)
