Best Minerals for Energy & Fatigue
These three minerals affect energy through different pathways, and the evidence for each depends heavily on whether a deficiency is present. Iodine's connection to energy runs through thyroid function — genuinely important, but supplementing beyond adequate levels doesn't speed up metabolism in someone who isn't deficient. Magnesium has modest human trial support for subjective energy and muscle function, with more consistent evidence for sleep than for daytime fatigue specifically. Copper's link to energy is the least direct of the three, tied to its role in iron metabolism and enzymatic function rather than a standalone fatigue claim. A blood panel is a better first step than stacking all three on a hunch.
