Magnesium RDA & Daily Intake

Do you meet the magnesium daily requirement?

The US government has established the recommended dietary allowance (RDA) of magnesium at 420 mg for men, and 320 mg for women. However, it is known that these requirements are set relatively low.1

Given that magnesium RDA’s are established as minimum intakes rather than optimal intakes, it is evident that magnesium deficiencies are far more widespread than is commonly recognized. Currently, 67% of Americans’ daily magnesium intake fails to obtain the relatively low amounts established as the recommended dietary allowance (RDA), or the newer dietary reference intakes (DRIs), which are set at correspondingly low values.

Magnesium Deficiency & Daily Requirement

In fact, one conclusion of many researchers is that magnesium deficiency states among the population may be as high as 90% (or higher). This is due to the fact that values for daily magnesium requirements represent minimum intakes not intended to support optimal health, and the fact that some people, due to biochemical individuality, may actually require many times the recommended magnesium intake.

At these endemically high levels of deficiency, it becomes probable that nearly all persons experience magnesium deficiency at one time or another, and that a perpetual state of deficiency is the common experience of millions of people in America and many other nations.

Recommended Magnesium Daily Dosage?

How should you determine your own magnesium daily dosage? What is increasingly clear is that there is a far greater need for increased magnesium intake than has been acknowledged by health officials or government panels. Equally evident is that the amounts of magnesium required for best health exceed the amounts the US government historically recommends.

According to Dr. Mark Sircus, Ac. OMD, author of Transdermal Magnesium Therapy, a daily magnesium intake of 3-4 milligrams per pound of bodyweight can provide a simple starting point for determining dosage,2 but individual factors must be taken into account. Most importantly, individuals with kidney disease or other chronic disorders should consult with their health provider for guidance.

When evaluating your daily dose of magnesium, keep in mind that every person is different, and that magnesium RDA may not accurately reflect your needs adequately. The recommended daily allowance of magnesium is set relatively low, and represents minimum intake levels rather than optimal intake.
