Topical Magnesium Chloride

  • Relaxes tense muscles
  • Eases aches and pains
  • Softens and smoothes skin
  • Helps with restless legs
  • Treats magnesium-deficiency
  • Highly absorbable


The latest addition to our MagTherapy line of products, NEW Magnesium Balm improves skin while delivering fast-acting transdermal magnesium. 

MagTherapy is made from magnesium chloride in its most natural state, with over 90 other trace minerals not found in lab-produced magnesium chloride. 

In this emollient balm, we've combined magnesium chloride with natural coconut oil, raw shea butter and beeswax.

MagTherapy Balm:

  • Penetrates through the skin to relieve tension better than Epsom salts
  • Helps restore healthy magnesium levels
  • Soothes, protects and boosts skin’s moisture retention

Use it anywhere for softer skin or rub MagTherapy Balm into areas of muscle pain and tension.

Contains approximately 200 mg of seawater-sourced magnesium chloride per teaspoon.

For full-strength transdermal magnesium, see our MagTherapy Liquid in the cap top bottle.

Magnesium absorbed through the skin is fast and effective.


Suggested Use:  Smooth into areas of tension or to seal in moisture on the body or face.

Ingredients: Magnesium chloride (concentrated from seawater), fractionated coconut oil, raw shea butter and beeswax.

Contains no fragrance, preservatives or anything artificial.

Dose: Each 1 tsp (5 ml) contains ~200 mg of magnesium, equivalent to ~60mg of elemental magnesium, plus over 90 naturally-occurring trace minerals.

Note that the ‘elemental magnesium’ measurement is most important for determining the dose that may be right for you. We recommend using about 1 tsp of the product for children and at least 2 tsp for adults, topically.

Cautions and Warnings: For external use only. Keep away from the eyes. This product should not cause skin sensitivity; however, should you experience redness, rash or irritation, discontinue use.


Can you really absorb magnesium through the skin? Consider the evidence from clinical studies:

  • A transdermal magnesium oil with a 31% magnesium concentration applied to the skin and via a foot bath was found to increase cellular magnesium concentration by 59.7% in 89% of study participants, measured through hair analysis1
  • In a two-week pilot study, blood serum and urinary magnesium concentration significantly increased in a subgroup of non-athletes following the low-dose application of 56 mg of transdermal magnesium cream per day2
  • Intracellular magnesium concentration significantly increased following the application of a transdermal magnesium chlorate spray to the skin for 4 months, measured by epithelial cell and blood serum analysis3

    How much would you put on a 2 year old? I need a Anwer before I try it.

    • Anna Bolton O’Byrne

      Hi there,

      A teaspoon will be fine.

      Magnesium chloride is a compound found in seawater, and just as you wouldn’t regulate your time spent in the ocean, you don’t need to worry about absorbing too much magnesium through the skin. The skin regulates absorption.

      Thank you,

    Does this help with constipation if it’s absorbed by the skin? How does that work?

    • Anna Bolton O’Byrne

      Thanks for your question! Anecdotally, there have been reports of transdermal magnesium (epsom salts in large quantities) affecting regularity. However, the model for magnesium absorption suggests that only when taken orally does it draw water into the bowels, relieving constipation. Research suggests magnesium applied to the skin goes directly into blood circulation (bypassing the GI tract) and excess is excreted through the kidneys.

    I’ve used the natural calm powder years and ago and started using it again a week ago because of stress and insomnia. I can’t remember why I ever stopped using it. It’s a life saver. I currently take 1 tsp in the morning and 1 before bed and I was wondering if applying a bit of the balm on my arms at night would help or would I be absorbing too much magnesium?
