From the Research

Magnesium sulfate is the best-researched form of magnesium for rheumatoid arthritis (RA), as evidenced by a recent study published in 2022 1. For those with RA, a typical recommended dosage is 300mg of elemental magnesium daily, which has been shown to reduce fasting blood sugar and insulin resistance in patients with RA. The study found that magnesium supplementation reduced the Homeostasis Model Assessment of insulin resistance (HOMA-IR) in patients with RA, suggesting a potential benefit for preventing type 2 diabetes in these patients. Some key points to consider when supplementing with magnesium for RA include:

  • Starting with a lower dose and gradually increasing to the recommended amount to minimize potential digestive issues
  • Dividing the daily dose into 2-3 doses with meals to improve absorption and reduce potential digestive discomfort
  • Considering the potential benefits of magnesium supplementation on insulin resistance and type 2 diabetes prevention in RA patients, as suggested by the study published in 2022 1 However, it's worth noting that other forms of magnesium, such as magnesium glycinate, may also be beneficial for RA patients due to their high bioavailability and potential anti-inflammatory effects, as suggested by other studies 2, 3. Ultimately, the choice of magnesium supplement will depend on individual patient needs and preferences, and should be made in consultation with a healthcare provider. Some studies have investigated the effects of different forms of magnesium on RA, including magnesium sulfate 1, and have found potential benefits for reducing arthritis severity and joint damage, as well as modulating the immune system and intestinal microbiome 2, 3. Overall, magnesium supplementation may be a useful adjunctive therapy for RA patients, and further research is needed to fully understand its potential benefits and optimal dosage and formulation.
