Our society thrives off trends, fads, convenience, and fashionable consumables. I’ve observed a growing popularity in magnesium sprays and oils, often given exposure on social media by companies and individuals, who possess little knowledge about health, nutrition, training or biochemistry. However, this doesn’t make them bad people as they often make up for their short comings in knowledge by demonstrating a superior ability to poll likes and brain wash an easily influenced audience.


Magnesium is a cofactor for over 300 enzymatic processes within the human body. Magnesium plays a role in ATP production, DNA, reproduction, and protein synthesis. More commonly understood are its benefits for regulating muscular contractions, blood pressure, insulin metabolism, neural and cardiac excitability, and improved sleep quality. Unfortunately, transdermal magnesiums over promise and under deliver.


The main selling points of magnesium sprays and oils hypothesise a concept based on greater absorption and by bypassing the gastrointestinal tract, less risk of side effects such as diarrhoea which is common if excessive magnesium is orally administered.


Transdermal magnesium is a waste of your time, effort, and money. Quite frankly, its cheap magnesium salts with poor bioavailability but a cleverly marketed product that speaks to societies lifestyle demands.


Let me explain some more….


The skin is the largest organ of the body. The primary function of the skin is to provide a barrier between the body and the external environment. This barrier protects against the permeation of ultraviolet radiation, chemicals, allergens and micro-organisms. This means that the absorptive capacity of healthy skin for substances from the outside is very limited.


The outermost layer of the skin is called the stratum corneum. The stratum corneum functions to from a water-repellent barrier to protect underlying tissue from infection, dehydration, chemicals and mechanical stress. Overcoming this layer in significant quantities is only possibility for lipophilic (fat soluble) substances. In magnesium chloride solution, magnesium is present in ionised form and therefore not able to penetrate a lipophilic layer.


Magnesium chloride is the main ingredient in magnesium spray and oils. Long story short, magnesium chloride has an extremely difficult time passing through the skin. If it didn’t, simply  swimming in the ocean could potentially kill you.


Coincidently, the websites that conduct or site “research studies” supporting the effectiveness of magnesium spray and oils tend to be promoting and selling the stuff. No genuine published health research or peer reviewed academia backing their claims is available. So even though it smells like science, it also has a slight smell of dog shit to it also.


My issues with these products continue…


High quality magnesium supplementation often requires a relatively large serving size e.g. Trilogy’s GABAMag recommends a 6-8 capsule dose. To think you could receive an equivalent level of magnesium from one or two sprays of a water soluble product is beyond farfetched even if it could be absorbed through the skin.


Trilogy has chosen to seek a higher standard of regulation by being certified by Australia’s Therapeutic Goods Administration (TGA) as one of the most strict and exacting regulatory regimes in the world.


Trilogy’s GABAMag also contains multiple different types of magnesium within its product. There are many different types of magnesiums that do different things and treat different tissue and symptoms.


Refer to https://gript.wpengine.com/magnesium-2/ for my favourite types of magnesium and why. None of which are magnesium chloride or sulphate.


Magnesium supplementation is extremely important because its almost impossible to obtain optimal levels without supplementation in todays world, given our soils nutrient richness has been so badly compromised.


Anyone who has experienced improved symptoms from transdermal magnesium is most likely under the influence of a placebo effect (a physiological response to a psychological response, believing they feel better, may actually result in feeling better). I suspect those who came up with these magnesium products potentially ingested bath salts throughout the trial periods instead of transdermal application.
