Vitamin D and Magnesium
Magnesium is an important mineral involved in over 300 different processes in the body, including the ability to make and use ATP, the body’s main form of energy.
Of those 300 roles, magnesium aids in a handful of activities related to vitamin D production and use. In particular, it seems to modulate the sensitivity of our tissues to vitamin D.
Not only does magnesium play an important role in proper Vitamin D activity and function, but crucially, it also helps to maintain calcium balance.
At least half of the population fails to meet the Recommended Dietary Allowance for magnesium. This may be because soil levels of magnesium have fallen considerably in the past 50 years, making it harder to meet our needs.
Because magnesium is used in vitamin D metabolism, some researchers theorize that supplementing with high levels of vitamin D could cause an even greater magnesium deficiency in an already deficient population.
Interestingly, a relatively recent study demonstrated a strong correlation between magnesium and vitamin D deficiency.
This study showed that magnesium supplementation, taken along with vitamin D supplementation, was more effective at correcting a vitamin D deficiency than vitamin D supplementation alone.
Simply by increasing magnesium intake, we may decrease mortality related to vitamin D deficiency — without taking any extra vitamin D.
