Aliquot #154: Do You Need a Magnesium Supplement?

Magnesium is easy to get wrong. Many people don't get enough from food, and blood tests don't always tell us whether intake is sufficient. Supplements can help fill the gap, but choosing one can get complicated. Forms like glycinate and L-threonate are promoted for different goals, and the evidence is not always clear. In this Aliquot, I explain how to assess your magnesium intake, increase it through food, and choose supplements based on evidence rather than marketing claims.
