Hands up if you have Fibromyalgia and have been told to supplement with magnesium? Yep, me too. I’ve been taking magnesium supplements for a few years now and, I’m not alone; many people take magnesium for Fibromyalgia and have reported benefits from doing so. But, have you ever wondered why magnesium is so important?

Today, I am going to explain why magnesium is an essential mineral, how it relates to Fibromyalgia and I’ll share a few things to consider when it comes to choosing a magnesium supplement. Plus, I’ll also introduce you to a great magnesium spray called Soothe Magnesium (and give you a 20% discount code!).

Why is Magnesium Important?

Did you know that magnesium is an essential mineral that is involved in more than 300 biochemical reactions within the body? It plays a role in energy production; protein synthesis; muscle and nerve function; blood pressure regulation; and blood glucose control to name just a few.

Magnesium also supports a healthy immune system, healthy heart function and helps to keep bones strong. In short, it is imperative to our health.

Dietary Sources of Magnesium

Magnesium can be obtained through our diet and it is naturally found in fruits, vegetables, nuts and seeds. Good sources of magnesium include dark, green leafy vegetables, such as spinach; brown rice; almonds; cashews; whole grains; soy and black beans.

However, despite being such an important mineral, many of us are not consuming enough of it. Dietary surveys consistently show that intake requirements for magnesium are not being met.

So much so, that it was reported as a health concern by the United States Department of Agriculture and United States Department of Health and Human Service back in 2005.

How is Magnesium Deficiency Linked to Fibromyalgia?

Low magnesium intake is common in the general population, but it is thought that having Fibromyalgia can put people at a higher risk of magnesium deficiency. There are a few factors that can deplete magnesium levels in the body, such as stress and hormonal disruption. But, probably the most significant for Fibromyalgia patients is sleep disruption.

Sleep deprivation has been shown to lower magnesium levels. And, we all know that poor sleep and Fibromyalgia go hand-in-hand. Plus, if magnesium is deficient, it can disturb the production of the sleep-regulating hormone Melatonin. So it’s an unfortunate chicken-and-egg cycle; disruptive sleep lowers magnesium and low magnesium causes poor sleep.

Magnesium for Fibromyalgia Symptoms

While it is unlikely that magnesium deficiency is a causative factor in Fibromyalgia, low magnesium can certainly make some of our symptoms worse. The four main Fibromyalgia symptoms that magnesium can play a role in are fatigue, brain fog, pain and of course sleep.

How Low Magnesium Worsens Chronic Fatigue

Going back to what I said earlier, magnesium is hugely important in the production of energy. This is because magnesium is required in the synthesis of ATP (the body’s energy currency).

If we have inadequate levels of magnesium, it essentially means that our bodies cannot produce ATP effectively. Put simply, low magnesium equals low energy production.

As it is thought that people with Fibromyalgia have low levels of ATP to start with (hence why chronic fatigue is a symptom), having a low intake of magnesium would make this situation even worse. This is definitely true of me and I have test results to prove it.

I was found to have low whole cell ATP and low ATP- related magnesium. This was despite the fact that I had already been supplementing orally with magnesium (which goes to show it’s important to supplement correctly and I’ll talk more about the changes my doctor made shortly).

Brain Fog & Low Magnesium

Poor levels of ATP is also linked to brain fog. It’s thought that approximately 20% of ATP is located in and used by our brain. Therefore, if our bodies are not producing adequate amounts of ATP, our brain function will suffer. So, not only is magnesium important for helping to improve energy levels, in doing so it can also be helpful for reducing brain fog.

Magnesium & Muscle Function

Magnesium is also important for normal muscle function as it helps to loosen tight muscles and promotes better flexibility. Low levels of magnesium can result in muscle cramps and a build-up of lactic acid, causing muscle pain. Therefore, it isn’t too far-fetched to suggest that low magnesium intake can make Fibromyalgia pain even worse.

Should You Supplement With Magnesium?

I would always suggest that you consult with your healthcare professional before supplementing with magnesium for Fibromyalgia. And, if you really wanted to be sure that you need to supplement, there are blood tests available to check your magnesium levels. The most common test offered is the serum magnesium test, which tests the level of magnesium in your blood serum.

It’s important to point out that serum magnesium can actually be normal but magnesium can still be low elsewhere in the body. Therefore, it isn’t the most accurate indicator of magnesium deficiency.
I was suggested to have a red blood cell (RBC) magnesium test, which looks at how much magnesium is inside red blood cells.

The RBC magnesium test is considered more accurate than a serum magnesium test. The reason for this is because the body takes from other cells when it is low in magnesium.

Therefore, if our red blood cells are lacking in magnesium it is an indicator of magnesium deficiency (as the low levels indicate magnesium is being depleted from red blood cells to be used elsewhere).

Fibromyalgia Patients Report Benefits From Magnesium Supplementation

No test is completely accurate an if you can’t afford to test, know that many people with Fibromyalgia report benefits from supplementing with magnesium and I am one of them. If science counts more than personal experience to you, then be sure to read this study that showed a reduction in fibromyalgia symptoms through supplementing with magnesium.

What to Consider When Choosing a Magnesium Supplement

There are many different magnesium supplements available to purchase; oral tablets, sprays and lotions. However, not all of them are created equally. It’s worth doing your research and finding a high-quality supplement as poor quality magnesium can be more harmful than good.

Avoid products with unnecessary fillers and additives and choose only the purest products. I always choose to purchase from companies who are transparent about what is in their product and who are honest about the source of their ingredients.

If you do decide to supplement, my advice would be to start slowly and build up the dose as excess magnesium has a laxative effect (magnesium oxide is most likely to cause this). Although this sounds horrid, it’s actually a helpful guide as if you ever experience this it means that you are over-supplementing.

Make sure that you follow the suggested dose to gain the most benefit. And, if you can work with your doctor this is always preferred to ensure that you are dosing optimally for you.

My Doctor Recommended Magnesium Supplements to Ease my Symptoms

I was recommended to take two forms of magnesium to help improve my fatigue and to reduce my pain. Initially, I was given a magnesium glycinate oral supplement. This was a different type of magnesium than I had used previously.

I believe I was given magnesium glycinate because I was prescribed a high dose and this form of magnesium is better tolerated by the gut.

I was also later prescribed a magnesium spray. This was when I was on antibiotics for my Lyme disease and, due to all the herxing, my pain had increased.

The Benefits of Using a Magnesium Spray

I was suffering from both increased muscle and joint pain. I was told by my doctor that spraying magnesium directly onto the source of pain would bring better relief as it’s more targeted than supplementing orally.

It’s also much easier to build up the dosage of magnesium using a spray as you can literally start from one spray and increase from there. However, I quickly learned that choosing the right product is important.

The spray I initially purchased did not agree with me. I found it uncomfortable, irritating and greasy. I’ve since learned that this is a common complaint when it comes to magnesium sprays. So if you have been put off by using a magnesium spray in the past, know that not all products are created equally.

Soothe Magnesium

I was recently introduced to a product called Soothe Magnesium, which is a spray that contains 100% pure, bioavailable magnesium derived from the Dead Sea. It is created by Nutrify Health in a GMP certified, FDA registered facility in the heart of Akron, Ohio.

Soothe Magnesium is food grade, toxin-free and food safe (you could literally spray it in your mouth it’s that safe). It contains no fillers, toxins or anything artificial, so it is a really high-quality, superior product.

Soothe Magnesium was developed over 10 month period with the help of a chemist to overcome the problems traditionally associated with magnesium sprays. It has been formulated to absorb well into the skin without causing any irritation or greasiness.

There is also a versatility to the product. It can be sprayed directly onto sore joints and muscles to ease pain and promote relaxation. Or it can also be added to bath water to create a muscle soak (as an alternative to Epsom salts).

Nutrify Health suggest using 30-50 sprays of Soothe Magnesium each day. This sounds a lot but broken down, it is 15-25 sprays each morning and night. Given that those of us with Fibromyalgia tend to hurt all over, it’s not difficult to use this much product as we need to use it on lots of different painful areas.

Used at night, Soothe Magnesium can help to relax muscles and promote calmness, which is helpful for sleep. Luke, the Founder of Nutrify, has actually found Soothe Magnesium super helpful for his sleep apnea. He told me that he sleeps more soundly when he uses the product at night.

Reviewing Soothe Magnesium

I fully intend to write a complete review of Soothe Magnesium and I will do so in the coming weeks. Soothe Magnesium is available to purchase directly from Nutrify Health or from and you can also check out and follow Magnesium Soothe on Facebook.

Hello, I'm Donna. I was diagnosed with Fibromyalgia in 2013 and started this blog shortly after. After my health declined significantly the following year, I decided to become my own advocate and searched for answers. It took two years but, in 2016, I finally discovered I had Lyme Disease. On February Stars, I share my personal journey back to better health; discussing what has helped me and the mistakes I've made along the way. I also cover topics on self-improvement, managing symptoms and living life to the fullest with chronic illness.


  1. I ordered 2, 2oz. spray bottles, and just paid shipping. I’ve always wanted to try the spray magnesium, and definitely trust your judgment when it comes to what products to buy. Thanks for the recommendation; I can’t wait to get it and try it.

    • Hey Deanna, you’re welcome and I really hope you like the spray. I find magnesium so helpful 🙂

  3. Very informative, thank you. I’ve tried magnesium before but never noticed any relief but think I may try again after reading this as my sleep is awful at the moment!. I remember making my own magnesium spray and being so proud. After using it where it had sprayed over other things everything turned white! And my shin was all itchy!!. Think I’ll try this Spray this time… Thank you. Xx

    • Hey Wendy, I’m glad you found the post helpful. It may be that you need to use it for some time before you start to see the benefit. It could be worth trying again to see whether it helps you. Oh no! Sorry to hear your homemade spray didn’t work out. It’s always worth a try and I hope you see a better response from using this spray 🙂

  4. If you want a more effective magnesium take Magnesium with Maliic Acid. Magic Acid is
    a known natural pain med. Works for me.
