Magnificent Magnesium: An Often-Overlooked Tool for Pain Relief

Magnesium takes part in over 300 biochemical processes. Protein building, muscle and nerve function, blood pressure regulation, blood sugar control: it has a hand in all of them. It also moves calcium into muscle and nerve cells, which shapes how nerves signal and how muscles contract.

Research associates higher magnesium intake with lower risk of heart disease, stroke, type 2 diabetes, osteoporosis, and migraine. Leafy greens, beans, nuts, seeds, and whole grains are all good dietary sources. At Ivy en Rose we offer IV magnesium, which bypasses first-pass metabolism. In some cases it may help break a migraine.

How Magnesium Helps with Pain

Part of how it works is by limiting how much calcium enters nerve cells. That reduces activation in certain nerve pathways involved in central and peripheral sensitisation, the processes that can leave the nervous system hyper-responsive to pain.

Magnesium may reduce nerve hyperexcitability and pain hypersensitivity. On that basis it has been studied for several painful neuropathic conditions, among them:

• Post-herpetic neuralgia (pain following shingles)
• Peripheral neuropathy
• Diabetic neuropathy
• Migraine headaches

Other medications will often take the leading role, but magnesium may be a useful addition to a broader pain management plan for some patients.

Choosing the Right Magnesium Supplement

It comes in several formulations, and which is best depends on your needs and how well you tolerate it.

Magnesium Glycinate

Generally well absorbed, and tends to cause fewer gastrointestinal side effects. Often a sensible choice if you want to raise magnesium levels without loose stools.

Magnesium Oxide

May suit people prone to constipation, since it can have a mild laxative effect.

Magnesium Threonate

Studied for possible effects on brain health and sleep. Some people find it supports healthier sleep patterns and better sleep quality.

Finding the right formulation for your physiology may take some trial and error, ideally guided by a healthcare professional.

Who Should Use Caution with Magnesium?

Magnesium is generally safe for most people, but talk to your healthcare provider before starting. Those at higher risk of a poor reaction include patients with:

• Heart disease, including heart block
• Kidney disease
• Intestinal disorders
• Neuromuscular conditions
• It can also interact with a number of medications and supplements, including:
• Certain antibiotics
• Thyroid medications
• Bisphosphonates (used for osteoporosis)
• Zinc supplements
• Calcium supplements
• In a Nutshell

Magnesium is an essential nutrient whose benefits reach well beyond general health. By helping regulate nerve activity and dampen pain signalling, it may offer some relief to people living with neuropathic pain, migraine, and other chronic pain conditions.

As with any supplement, discuss magnesium with your healthcare provider to work out whether it suits your health needs and your current medications.
