#087 The Science of Magnesium and Its Role in Aging and Disease | Dr. Rhonda Patrick

Found My Fitness - Rhonda Patrick

Key Takeaways Magnesium is an essential mineral required for more than 300 metabolic reactions in the body but almost half the U.S. does not have sufficient levels (partly because of poor diet)One theory of aging: when we have suboptimal dietary intake, our body sacrifices the long term for the short term, producing insidious damage overtime that accelerates agingStress will lower magnesium levels, even for days after stress passesFlaws of supplement and nutritional study design: randomized controlled trials are the gold standard for pharmaceutical interventions, but, nutritional studies need to consider individual nutrition and improve study design at the outset with consideration for baseline levels of participants if we want real answers

Most studies are also observational so you can’t infer causalityMicronutrients also often work in conjunction with one another – for example, magnesium is necessary for the conversion of vitamin D into its most stable formMost of the positive benefits of magnesium come from studies on dietary magnesium not supplementation

Confounding: magnesium is found in leafy greens, legumes, nuts, fish – and healthier foods; it may not be solely the magnesium that’s improving health
