Sore arms and legs could this be magnesium deficiency?

Answer 1

Yes. A common sign of magnesium deficiency is sore, achey muscles. The reason is found in magnesium's role in relaxing muscles. It works on the cellular level as a calcium channel blocker (calcium stimulates muscles, magnesium relaxes them). So when you don't have enough magnesium, calcium can rush into the cells and overstimulate muscles, causing them to be painful.

You can try getting more magnesium in your diet through foods like nuts and seeds and green leafy vegetables, but it can be difficult to get enough to replenish a magnesium deficiency...not to mention that our soils are generally very magnesium deficient too. Magnesium supplements could be needed.

Magnesium oxide is the most common form of magnesium you will find, but it's also the least well absorbed. Chelated forms (like dimagnesium malate from Albion Labs) are more bioavailable, and sustained-release forms of these are the best because they aren't as likely to cause diarrhea, like most magnesium supplements will at high enough doses.
