Magnesium potentially benefits CFS patients
Red blood cell magnesium and chronic fatigue syndrome.
High relevance for CFS treatment
We investigated the relationship between magnesium levels in red blood cells and chronic fatigue syndrome (CFS). A case-control study revealed that CFS patients had lower magnesium levels than healthy individuals.

In a randomized, double-blind trial, 32 CFS patients received either magnesium sulphate or a placebo for six weeks. Those treated with magnesium reported significant improvements in energy, emotional wellbeing, and pain relief, with twelve out of fifteen feeling better.

In contrast, only three out of seventeen patients on placebo reported any improvement. Overall, these findings suggest that magnesium treatment may positively impact the wellbeing of those suffering from CFS.

Magnesium sulfate shows potential benefits
[A case of chronic fatigue syndrome who showed a beneficial effect by intravenous administration of magnesium sulphate].
Relevant study on treatment efficacy
We aimed to understand the effects of magnesium sulfate treatment on a patient with chronic fatigue syndrome. The case involved a 29-year-old woman experiencing severe fatigue alongside various symptoms, including swelling lymph nodes and muscle pain.

After other treatments failed to provide relief, we administered magnesium sulfate intravenously once a week. Remarkably, after six weeks, the patient reported a significant reduction in fatigue and improved daily functioning, eventually leading to her discharge from the hospital.

Magnesium shows limited benefit for fatigue
Magnesium status and parameters of the oxidant-antioxidant balance in patients with chronic fatigue: effects of supplementation with magnesium.
Moderate relevance due to mixed results
We investigated how magnesium levels relate to chronic fatigue by studying 93 patients with unexplained fatigue.

Around 47% of participants showed magnesium deficiency, linked to reduced plasma antioxidant capacity.

Although magnesium supplementation didn't increase blood glutathione levels, we observed improved magnesium stores and vitamin E levels.

However, this did not equate to a significant boost in antioxidant activity or a decrease in lipid vulnerability. Therefore, while magnesium may help improve some parameters, it is not a panacea for chronic fatigue syndrome.

Improved sleep quality
After taking magnesium, I found I became much calmer, my sleep improved, and my legs stopped hurting. Magnesium is crucial for our bodies and is recommended for pregnant women. I take 2 capsules after meals or 30-40 minutes before bedtime. Since using this product, I sleep well, feel less fatigued, and manage my duties as a mother more effectively. I highly recommend it; the quality matches the price, and I appreciate the capsule size.

Magnesium shows promise for CFS
[Therapy of chronic fatigue syndrome].
Effective treatment still uncertain
We explored the effects of magnesium on chronic fatigue syndrome (CFS), a condition marked by extended periods of debilitating fatigue. While there’s no definitive therapy established for CFS, our review of clinical trials reveals that magnesium treatment has shown promise, enhancing the well-being of some patients.

Other treatments like acyclovir have proven ineffective, and although intravenous immunoglobulin therapy shows potential, its results remain debated. We recognize that restoring immune function may be a piece of the puzzle, but overall, the effectiveness of magnesium for treating CFS symptoms is yet to be firmly established.

Limited magnesium effectiveness in CFS
Complementary and alternative medicine for patients with chronic fatigue syndrome: a systematic review.
Study demonstrated partial relevance
We systematically reviewed randomized controlled trials on complementary and alternative medicine (CAM) treatments for chronic fatigue syndrome (CFS).

Although 26 studies involving over 3,000 participants explored various therapies, the findings showed limited effectiveness overall.

While some treatments like massage and specific dietary supplements had some positive effects, most failed to provide significant benefits.

Notably, magnesium showed potential, but due to small sample sizes and biases in the studies, we can't make firm conclusions just yet. More rigorous studies are needed to confirm these effects.

Replenishes deficiency
CHELATED FORM OF MAGNESIUM! Most people are magnesium deficient, which can cause chronic fatigue syndrome and other health issues. This supplement helps replenish magnesium levels effectively, improving sleep quality by regulating cortisol levels.

Regulated bowel movements
The supplement helped my wife, who has Irritable Bowel Syndrome and chronic fatigue syndrome. After years of struggling with constipation, this has significantly improved her bowel movements to twice daily. The magnesium complex is high quality and easy to ingest.
