What research says

Studies in people

  • Open question

    Stomach emptying speed2

    In people, taking magnesium chloride slowed how fast the stomach emptied, but it did not change fat digestion.

Single cases of misuse or overdose

One person or one incident, such as an accidental overdose or a mistake in a kitchen or factory. They are real, but a single case does not show what happens at normal amounts, so the signal does not count them.

  • Fatal mineral overdose1

    A woman died after drinking milk with magnesium chloride, a folk remedy, raising her magnesium to a deadly level.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted. This page is a reference, not medical advice. It describes what regulators and published research say. Talk to a doctor or dietitian about your own diet.

What expert reviews concluded

Expert panels that weigh all the research. Shown for context: the signal at the top does not count them.
