Fatigue & mental clarity — what magnesium and iron really do

A calmly written guide to how two minerals contribute to the reduction of tiredness and to normal cognitive function — based on EFSA-reviewed claims.

The Problem

Persistent tiredness and the feeling of being mentally “in a fog” are often blamed on stress or lack of sleep. The quiet cause is rarely considered: an inadequate supply of minerals that are indispensable for energy-yielding metabolism and cognitive function.

EFSA-reviewed minerals at the center of this guide

Pages of clearly presented information

Scientific basis

Two minerals. Two authorized claims.

Each claim below has been reviewed and authorized by the European Food Safety Authority (EFSA).

Magnesium

EFSA-authorized claim: Magnesium contributes to the reduction of tiredness and fatigue

Magnesium acts as a cofactor in numerous enzyme systems involved in cellular energy production. Magnesium contributes to normal energy-yielding metabolism — the biochemical basis for the body not running out of steam too early.

Iron

EFSA-authorized claim: Iron contributes to normal cognitive function

Iron is a vital component of hemoglobin and thus ensures oxygen transport to all organs, including the brain. An adequate iron intake contributes to normal cognitive function in everyday life.
