Magnesium Glycinate
Reviewed by the Nimbera editorial team · Last updated May 2026
How to use
Take 300-400 mg elemental magnesium as glycinate or malate form nightly before bed. Glycinate is gentler on the digestive system and supports sleep; malate may support cellular energy (ATP production). Start at 200 mg and increase over 1-2 weeks to assess tolerance. Pair with vitamin D3 for synergistic benefit.
How it works
Magnesium is a cofactor in over 300 enzymatic reactions including all ATP synthesis pathways. Post-viral illness depletes magnesium through stress hormone activation and inflammation. Magnesium deficiency impairs mitochondrial energy production, worsens neurological symptoms like brain fog and anxiety, disrupts sleep architecture, and amplifies inflammatory signaling.
