More information about magnesium levels

Magnesium levels tend to be lower among those who don’t take a magnesium supplement or multivitamin that contains magnesium. Although it’s rare to have optimal or high magnesium status from diet alone, symptomatic magnesium deficiency is uncommon. 

An estimated 48% of Americans consume less than the recommended amount of magnesium. Reasons behind magnesium inadequacy might include the following:

  • Consuming an inadequate amount of magnesium from food, as only 30-40% of dietary magnesium is absorbed properly. You can learn more about food sources of magnesium here.
  • Having a condition of the small intestine that would impair absorption (such as IBD or Celiac disease)
  • Having a kidney condition (including type 2 diabetes) as magnesium is processed in the kidneys

Supplementation: Baze dietitians recommend a supplement for those who measure below our optimal range, unless you requested to remove it.
