Magnesium: A potential breakthrough in managing fibromyalgia and migraines – new studies offer hope

• A 2022 clinical trial found magnesium supplementation reduced pain and stress in fibromyalgia patients, particularly those with moderate stress levels. Magnesium regulates nerve function, muscle relaxation and ATP production, addressing key symptoms.
• While overall stress reduction was modest, a subgroup saw pain scores drop from 5.7 to 5.1 (on a 10-point scale). However, magnesium did not improve sleep or fatigue, highlighting its role as a complementary—not standalone—therapy.
• Magnesium blocks overactive NMDA receptors (reducing pain signals), relaxes muscles by balancing calcium and supports ATP production for energy. It also stabilizes neuron activity and neurotransmitter release.
• Bioavailability varies by form—magnesium glycinate (calming), L-threonate (neuroinflammation) and citrate (constipation relief) are preferred. Avoid poorly absorbed forms like magnesium oxide. Dietary sources (leafy greens, nuts, seeds) and Epsom salt baths enhance absorption.
• Magnesium deficiency is often underdiagnosed due to unreliable blood tests. It may interact with medications (e.g., blood pressure drugs). While not a cure, its safety and affordability make it a key tool in chronic pain management, warranting further research on dosing and delivery.

Fibromyalgia, a chronic condition marked by widespread pain and fatigue, has long defied simple solutions. However, a 2022 clinical trial and mounting evidence suggest magnesium — a mineral critical for nerve function and energy production — may offer relief for millions. The study, which tested magnesium supplementation on fibromyalgia patients, revealed a nuanced yet promising effect: participants with moderate stress levels experienced significant reductions in stress and pain scores. These findings, coupled with historical trends of widespread magnesium deficiency, position the mineral as a cornerstone of future treatment strategies.

Magnesium’s subtle but substantial impact

The 2022 trial, though small, marked a milestone in understanding magnesium’s role in fibromyalgia. Researchers administered a slow-release magnesium supplement or a placebo to participants over a month. While overall stress reduction trends were weak, a subset of patients with mild to moderate stress saw a substantial drop in stress scores. Pain severity also eased: in this subgroup, scores declined from 5.7 to 5.1 on a 10-point scale—a modest but meaningful improvement.

Dr. Jodi Duval, a naturopathic physician, emphasizes that magnesium deficiencies are often the first clue in persistent pain cases: “Lower magnesium levels may disrupt cellular processes critical for pain modulation, making supplementation a foundational step,” she explains.

However, results aren’t universal. Sleep quality and fatigue remained unchanged across groups, underscoring that magnesium is a complementary tool, not a cure-all. A 2008 migraine study, however, demonstrated stronger effects: 80% of patients administered 1g of intravenous (IV) magnesium reported pain relief within 15 minutes — a stark contrast to placebo groups.

The science behind magnesium’s pain-relieving effects

Magnesium’s analgesic properties stem from its role in cellular processes:

1. NMDA receptor blockade: Magnesium curbs overactivity of NMDA receptors, which can amplify pain signals by allowing excessive calcium into neurons. This mechanism is pivotal in conditions like fibromyalgia, where heightened pain sensitivity is common.
2. Muscle relaxation: By regulating calcium balance, magnesium prevents muscle spasms and tics, common in fibromyalgia.
3. ATP support: Magnesium aids ATP production, addressing energy deficits linked to chronic pain and fatigue.

Emma Laing, a registered dietitian, highlights magnesium’s dual role in nerve health: “It stabilizes electrical potentials in neurons and supports neurotransmitter release, modulating pain pathways at multiple levels.”

For migraines, low magnesium levels disrupt brain excitability and blood vessel constriction. Studies show oral or IV magnesium can reduce both attack frequency and severity by stabilizing these processes.

Choosing the right form of magnesium matters

Not all magnesium supplements are created equal. Forms differ in absorption rates, tolerability and targeted effects. Here are some of the most common:

• Magnesium glycinate: Well-absorbed and calming, ideal for muscle tension and stress.
• Magnesium L-threonate: Crosses the blood-brain barrier effectively, addressing neuroinflammation in migraines.
• Magnesium citrate: Cost-effective and proven for constipation, but may cause diarrhea.
• Avoid magnesium oxide: Poorly absorbed and prone to laxative effects.

There are several others, including chloride, aspartate and malate, so be sure to do your own research to find which is best for you.

Dr. Duval notes that “bioavailability drives outcomes — slow-release formulations like glycinate or Epsom salt baths may be more effective for sustained tissue absorption.”

Beyond pills: Dietary and lifestyle strategies

Dietary magnesium is abundant in pumpkin seeds, leafy greens and dark chocolate — foods that should be staples for chronic pain management. Slow magnesium absorption and potential deficiencies in bioavailable forms mean supplementation often complements dietary intake.

Epsom salt baths (magnesium sulfate) offer an alternative route for skin absorption, easing muscle soreness without the digestive side effects of oral supplements. However, blood tests for deficiency can be misleading, as only 1% of total magnesium circulates in blood. Tissue levels often remain low even with normal serum results, necessitating symptom-driven trial-and-error.

Cautionary notes

While magnesium’s benefits are clear, its effectiveness has been underappreciated due to measurement challenges and low public awareness. A 2007 paper highlighted its role in sleep disturbances — common in fibromyalgia — and insulin resistance, showing how deficiencies exacerbate metabolic issues.

Caution is advised in those on blood pressure medications or diuretics, as magnesium can alter drug efficacy. Collaborating with a healthcare provider to balance risks is critical.

Magnesium as a pillar in chronic pain management

Magnesium’s multifaceted role in pain relief—blocking receptors, balancing minerals and supporting energy—is now backed by rigorous studies. While not a singular solution, its safety, affordability and widespread availability make it an attractive option for those struggling with fibromyalgia, migraines, or musculoskeletal pain. It is a critical cofactor for more than 600 enzymatic reactions in the body including everything from nerve and muscle function to breaking down food into essential nutrients to helping build hormones, neurotransmitters, bone health and DNA.

Future research must clarify optimal dosages and delivery methods, but for now, the evidence suggests: “Even small, consistent steps toward higher magnesium intake can make a difference,” says Duval. As patients and providers navigate chronic pain’s complexities, magnesium’s time has come.

For those balancing hope and skepticism, the journey starts with a seed—and perhaps, a handful of pumpkin seeds.
