From the Research

Oral magnesium supplements generally do not significantly interact with statin medications like atorvastatin (Lipitor) or simvastatin (Zocor) when taken at standard supplemental doses, and can be taken together without concern for reduced efficacy of the statin medication. The most recent and highest quality study on the topic of statin interactions is from 2020 1, which discusses the pharmacokinetic aspects of drug-drug interactions with statins, but does not specifically mention magnesium. However, an earlier study from 2004 2 provides insight into the mechanisms of magnesium and statins, suggesting that they work through different pathways, with magnesium acting as an electrolyte and enzyme cofactor, and statins inhibiting cholesterol production in the liver.

Some key points to consider when taking oral magnesium supplements with statin medications include:

  • Timing: separate magnesium supplements from statin doses by at least 2 hours to avoid any potential minor interference with absorption
  • Dosage: standard magnesium supplements (typically 200-400mg elemental magnesium daily) are considered safe alongside statins for most people
  • Potential benefits: magnesium supplementation might actually help reduce muscle pain or weakness symptoms experienced by some patients taking statins, as magnesium deficiency can contribute to muscle complaints

It's essential to note that while the evidence suggests that oral magnesium supplements do not significantly interact with statin medications, individual results may vary, and patients should consult their healthcare provider if they experience new or worsening muscle pain while taking both. The evidence from various studies, including those from 2003 3, 2004 2, 2005 4, and 2020 1, supports the safety and efficacy of taking oral magnesium supplements with statin medications, but it's crucial to prioritize the most recent and highest quality study, which in this case is from 2020 1. Additionally, a 2021 study 5 on the effects of oral magnesium therapy for hypertension provides further insight into the safety and efficacy of magnesium supplementation, but its relevance to statin interactions is indirect.
