A combination of magnesium and malic acid tops the list of recommendations for easing pain and fatigue, especially for those with fibromyalgia or ME/CFS.

Magnesium (Mg) is one of the most important nutrients required by our bodies. It is necessary for more than 300 biochemical reactions in the body and is essential to human life. A few of magnesium’s functions include:

  • Maintaining normal muscle and nerve function.
  • Keeping heart rhythm steady.
  • Supporting a healthy immune system.
  • Keeping bones strong.
  • Regulating blood sugar levels.
  • Promoting normal blood pressure.
  • Supporting energy metabolism and protein synthesis.(1)

Since our bodies don’t produce this essential nutrient, it is critical that we replenish our supply of magnesium daily through diet and/or supplementation.

According to a 1985 USDA survey, 75% to 85% of American adults consume less than the recommended daily amount of magnesium.(2)

Why We’re Not Getting Enough Magnesium

One reason Americans tend to run low on magnesium is that we eat a lot of processed foods, which usually contain very little magnesium. Magnesium is mostly found in green vegetables, nuts and seeds, whole grains, some legumes, and – you’re going to love this – chocolate.

But wait – that’s not the whole story.  What we gain by eating those magnesium-rich foods can be depleted by eating breads and pastas made from bleached and refined flour. Natural diuretics like coffee, tea and alcohol are also magnesium depleters.

A poor diet is not the only culprit, though. Another big reason so many people have a magnesium deficiency is that several commonly prescribed drugs strip our bodies of magnesium. These include oral contraceptives, estrogens, diuretics, corticosteroids, some diabetes drugs, and a number of antibiotics.

A magnesium deficiency can be related to a surprising number of illnesses including fibromyalgia, ME/CFS, migraines, type 2 diabetes, osteoporosis, asthma, high blood pressure, heart disease and PMS.

It can be difficult to detect a magnesium deficiency.

Most nutritional deficiencies can be revealed through a blood test. But because adequate serum levels of magnesium are essential for the heart to function properly, the body works overtime to maintain its blood serum Mg levels – at the expense of our cells and bones. So, even if a blood test shows normal serum magnesium levels, your cells, bones, and muscles may be severely deficient.

Fibromyalgia and Magnesium Deficiency

Researchers have found that people with fibromyalgia are commonly deficient in magnesium. Therefore, it’s not surprising that the symptoms of a magnesium deficiency are quite similar to many of the symptoms common to FM:

  • Insomnia
  • Fatigue
  • Irritability
  • Headaches
  • Muscle spasms and cramps
  • Poor memory
  • Confusion
  • Nervousness
  • Anxiety
  • Depression

Several of magnesium’s functions are directly related to FM symptoms:

Magnesium is involved in the production of serotonin.  Serotonin is a neurotransmitter involved in regulating sleep cycles, pain perception, mood and the immune system. People with fibromyalgia typically have low serotonin levels, which can be related to the sleep disturbances, increased pain and mood problems they often experience.

A magnesium deficiency can cause an increase of substance P.  Substance P is a neurotransmitter that serves as a pain messenger. People with fibromyalgia usually have exceptionally high levels of substance P, which can contribute to their hypersensitivity to pain.

Magnesium activates adenosine triphosphate (ATP).  Energy is supplied to our bodies by the mitochondria in the form of ATP.  Researchers have found evidence of mitochondrial dysfunction in fibromyalgia patients, which would result in the severe fatigue reported by most.(3)

Fibromyalgia and Malic Acid Deficiency

Researchers have found that people with fibromyalgia have decreased levels of oxygen in their muscles, also known as muscle hypoxia. Biopsies of those muscles have shown muscle tissue breakdown, mitochondrial damage, and low levels of ATP, which helps explain the widespread muscle pain characteristic of FM.

Evidence suggests that malic acid can help ease pain caused by muscle and tissue hypoxia. It allows the body to make ATP – and thereby energy – more efficiently, even under low oxygen or hypoxic conditions. Malic acid also enhances cellular stamina and endurance. (Malic acid is derived from food sources such as tart apples and is used/synthesized in the mitochondria as part of the ATP-producing citric acid or ‘Krebs’ cycle.)

As a team, malic acid and magnesium work together especially well to fight aluminum toxicity, which is thought to play a role in fibromyalgia. Malic acid acts as a potent aluminum detoxifier, while magnesium prevents future aluminum build-up.

Magnesium and Malic Acid Combo Reduces FM Symptoms

In a 1992 study, 15 fibromyalgia patients were given 300-600 mg of magnesium and 1200-2400 mg of malic acid for periods of four and eight weeks.  Participants reported reductions in pain across a tender point index. Notably, six of the patients experienced improvement in 48 hours.(4)

A clinical trial conducted in 1995 tested a proprietary tablet containing 200 mg of malic acid and 50 mg of magnesium on 24 fibromyalgia patients. After taking three of the low-dose tablets twice a day for four weeks, participants noted no significant change in symptoms. However, when the doses were escalated (up to six tablets twice a day) for six months, they experienced significant reductions in the severity of pain and tenderness.(5)

ME/CFS and Magnesium Deficiency

A 1991 case-control study found that 20 patients with ME/CFS had lower red cell magnesium concentrations than did 20 healthy matched control subjects. In the associated clinical trial, 32 ME/CFS patients received either placebo or intramuscular magnesium sulfate every week for six weeks.

The patients treated with magnesium reported having improved energy levels, a better emotional state, and less pain. Red cell magnesium returned to normal in all of the patients on supplemental magnesium, but in only one patient on placebo. The authors concluded that magnesium may have a role in ME/CFS.(6)

A number of leading ME/CFS specialists, including Daniel Peterson, MD, Jay Goldstein, MD, Jacob Teitelbaum, MD, Charles Lapp, MD, and Paul Cheney, MD, recommend a combination of malic acid and magnesium for muscle health and improved energy.

In his “From Fatigued to Fantastic” newsletter, Dr. Teitelbaum said, “Magnesium and malic acid are also critical. When malic acid and the other compounds are low, the body often has to shift to the very inefficient (anaerobic) means of generating energy. This contributes to the abnormal buildup of lactic acid that occurs after exercise in CFIDS/FM. This causes muscle achiness and fatigue.”

How Much Magnesium/Malic Acid Should You Take?

Three of ProHealth’s Double Strength Ultra ATP+ tablets contain 125 mg of magnesium and 1200 mg of malic acid – a very effective balance based on years of patient experience. The recommended starting dose is three tablets taken an hour before breakfast and at bedtime. The dosage can be gradually increased as needed.

Dr. Sarah Myhill says, “Magnesium is extremely safe by mouth – too much simply causes diarrhoea. Try increasing the amount of magnesium you take by mouth until it causes diarrhoea, then reduce the dose slightly so it does not. This is called taking magnesium to bowel tolerance…”(7)

Some people taking magnesium and malic acid have noticed symptom improvement in as little as 48 hours; however, it may take as much as four to six weeks.


Magnesium and malic acid are essential nutrients, yet most people are deficient in them. Their pain relieving, energy producing and mood stabilizing qualities can be particularly beneficial for people with fibromyalgia and ME/CFS.

    The most significant improvement in my pain has been due to magnesium and magnesium malate. I take 500mg magnesium and 150mg Malate. Even one day without magnesium results in more muscular pain in calves, wrists, forearms and lower back. Two days without magnesium results in muscle cramps. No other supplement has that obvious effect

  2. donnapowell25@hotmail.com says:

    Can I buy Malic Acid at Health store or walmart???? Any ideas on help with my pain from fibromyalgia & fatigue. Please help with any ideas!!!!

  3. LittleBluestem says:

    Blood tests may not detect Mg deficiency, but tissue (hair) mineral analysis will. I have ME/CFS and I have borderline low Mg despite having taken supplemental Mg.

    Malic acid is often supplied as magnesium malate. You can get it at health stores.

    I went into my friendly local Health Food shop for some more Magnesium.

    The capable assistant steered me instead to “Mineral Power” by Radiance (www.healthandherbs.co.nz), which contains:
    Calcium 500mg
    Magnesium 250mg
    Potassium 50mg
    L-Glutamic Acid 25mg
    Zinc 11mg
    Iron 10mg
    Silica 10mg
    Manganese 2.5mg
    Boron 1.5mg
    Vitamin D 100iu
    Copper 500mug
    Iodine 75mug
    Chromium 50mug
    Molybdenum 25mug
    Selenium 25mug
    Vanadium 25mug

    I had had an arm injury for a while, and had bought some Voltaren gel to put on it. After my first multi mineral tablet, the pain completely went away, and has never come back. I still haven’t opened the tube of Voltaren.

    I felt an immediate bloom of energy, and have been able to exercise more easily (at least until the current heat wave). I was able to increase the level and intensity of weight training, and now feel quite a bit stronger, and less liable to injury. It has increased my experience of well being.

    However, a recent attempt to clean up my paths left me bed bound for three days, so my stamina is still in very short supply. And with the heat I’ve been too listless and sweaty to continue with exercise.

    But my muscle aches haven’t come back, and I can feel my body flexing for a cooler day to get back to the weights.

    This is not a cheap supplement. But it is so much better value than just a Magnesium tablet. It proves I think, that I have been nutritionally deficient in many ways. At least with minerals, these are not just flushed from the system like vitamins. I wonder what else my body is currently missing? I still don’t feel “normal” or how I felt before I got ill. But I am starting to see glimpses of it.

  5. srambo says:

    Both can be purchased on line at Swansons Health Products. Regarding what type of magnesium, I have read online that magnesium malate is one of the best for absorption. Good luck!

  6. Webmind says:

    A little strange that most of the studies cited are 20-25 years old. What does that say about the current state of research for these diseases? We all need to get active and get the mainstream medical establishment to take this seriously and invest in our health.

    Imagine if the $trillions wasted on the war in Iraq/Afghanistan had been put into CFS research. Probably would have a cure by now.

  7. herenow23 says:

    After a missing some supplements for a while with the guidance of the kind people here on this site I am working towards a more comprehensive protocol.

    In regards to coffee and magnesium – I just read that brewed coffee from grinds just using tap water has 600 mg of magnesium. And that coffee, brewed, espresso, restaurant-prepared, decaffeinated Magnesium: 15999 mg; whatever that means and if that is true? Therefore, that might help offset some of the magnesium lost due to coffees diuretic effect? Either way, I supplement with the Ultra ATP, Magnesium + Malic Acid here from this site to be sure. The supplement I’m taking has been the most tolerable for my gut to date. I have purchased other products that are supposed to be more kind to the gut, but this one appears to be the best to date for me. I started with one tablet, then two, and I will work my way to higher doses. I have seen some benefit it appears.

    Best intentions and be well :)))

    I have taken source naturals’magnesium malate’
    Found at vitimin shope or online at swanson. The recomended dose equals 425mg mag and 2.5g malic acid.
    I have taken this for years and have found it more vital to pain management and general wellbeing than any perscribed or over the counter item. It does not fix everything but when i am without it i go into flares within days.
    I also take 2-3D3 5000iu and zinc plus a good multi vit.
    I have been diagnosed for over 20yrs and been on most everything. THIS WORKS.

  9. tmaree says:

    You have to use a magnesium malic acid formula for the best results. This article is great explains it all.I use Magnesiun malate 1,3000mg from Natureslife I bought at health store.After reading this article i dont think ive been using enough, and I do get t tired of taking so many pills. But maybe if I up my magnesium It will be better honestly I dont take regularly I will change that.starting now.

  10. athena1953 says:

    I’ve been taking this and can’t detect any difference in my pain or fatigue. Nothing at all helps me. I give up.

      I have had fibromyalgia since May, 1995. I also had aluminum poisoning, literally off the chart. My fibro pain levels became so high that I felt as though I were on fire from the inside out. When the poisoning was finally diagnosed, I found that 400mg of magnesium and 1600mg of malic acid were recommended, together, until my aluminum levels were down to a tolerable level. I had to take those for over 1 1/2 years to rid my body of the high pain levels and much of the aluminum. Unfortunately, I still have a fairly high level of aluminum and will have to go back on the magnesium and malic acid. Have the patients in the article also been tested for metals poisoning? Also unfortunately, mercury poisoning (from having old mercury fillings removed all at once – doing it one at a time is the only safe way, despite all the dentists’ precautions) cannot be treated with the magnesium and malic acid, but must be treated with slow (about 20 minutes) IV treatments by a physician with a special drug. It works to alleviate much of the pain as well, but takes years to complete. My energy levels are way up, and my pain levels are tolerable, thanks to ridding my body of so much aluminum.

    2. angel6113 says:

      I read the book mentioned in the article, from Fatigued to fantastic by Dr. Teitelbaum. I did begin taking magnesium & malic acid as well as HTP and GABA dietary supplements. It certainly helped fibromyalgia.

    3. angel6113 says:

      I would recommend that you read the book by Dr. Jacob Teitelbaum called from Fatigued to Fantastic if you have not. Google his name since he also has a website where you can sign up for emails, fibro medical info and free webinar. I suffered from this for 7 long years and feel like a new person now. Something else that helped me very much was prayer by others and much time myself spent in prayer. I read the book Healed from Cancer written by Dodie Osteen. She was given 3 weeks to live since she was diagnosed with liver cancer several years ago. She is still alive today and is Joel Osteen’s mother. I read the 40 healing scriptures in the book out loud each day for 7 years. The book of Proverbs says that God’s words are life to your flesh and healing to your marrow. It also says in Prov. 18, life and death are in the power of the tongue. That is why reading the word of God out loud helps. I also found that watching Ken and Gloria Copeland, Benny Hinn & Creflo Dollar were very inspiring to me since they teach about healing on their tv shows as well as one their websites. Go to kcm.org for the Copeland’s website. God Bless You!

    Magnesium oxide is the cheapest form; it is also poorly absorbed so it’s mostly a waste of money and depriving you of the magnesium you think you’re getting. Any of the other chelates are fine — I’ve been taking powdered (no additives used in making pills) magnesium citrate for years. In fact, it was the first supplement where I noticed an immediate reduction in fatigue — most likely I, like most people, was deficient. While it is in the foods mentioned in the article, what they don’t say is that the amounts are low (search “magnesium amounts food”) with a few exceptions (e.g., 5 oz. of almonds or cooked spinach will provide 400 mg. — the RDA for adults, although this, like many RDAs, may be set too low).

  12. yodecat says:

    in either the citrate or the maleate forms causes crazy crapping. However, I feel much better overall taking the maleate form daily.

    1. JerseyKat1 says:

      I would like to know what form of magnesium is best to take? The form that’s in most of what you buy in the drugstore is magnesium oxide…is this a heavy metal?

    2. dddiam says:

      Here is a quote from the magnesiumcomaprison link in the above posting:

      “RWM says:
      Not all magnesium has laxative effects. The higher quality magnesium, such as magnesium glycinate, magnesium malate, and madgnesium taurate, do not have laxative effects. Other forms of magnesium, such as magnesium oxide and magnesium citrate, have laxative effects.”

    3. lsmiaka says:

      I have seen here and elsewhere that tea is a magnesium depleter. Does taking it with either green tea or coffee in the morning therefore reduce its effectiveness? What about malic acid? I’d hate to try these remedies for fibromyalgia and render them useless. Thank you!

    4. Fibromimi says:

      Can anyone help me out on how much magnesium malate I should be taking?
      So far ,been using ionic magnesium ,magnesium citrate,till I bought a new supplement of magnesium with malate,taurine,magnesium (glycinate)pyridoxal -5 phosphate and it seemed to help a little for my fibromyalgia.
      Don’t know which of these ingredients are working for the pain .

    5. pepperlove says:

      I have been searching for a kind of magnesium which does not set off my IBS. I saw a homeopath and was prescribed a magnesium product. It set off a month of agonizing pain as if glass was grinding through my insides. I write this as one of the Dr. reviews, stated you cannot take too much, it will just give you diarrhea. If you have IBS, it can do much more than than. Just to give you feedback. I’m still looking for a good magnesium, because I have muscle cramps, which interfere with life and sleep. any thoughts?

      Have you tried Magnesium L-Threonate. I use this supplement and purchase it from dr.mercola.com I have IBS and this does not seem to cause diarrhea for me.
