When should someone supplement with magnesium?

Supplementing with magnesium can be beneficial if you're deficient in the mineral. Andrew Huberman highlights that many people might already get enough magnesium from their diet. However, supplementation is often considered for its potential benefits in promoting sleep, muscle recovery, and cognitive function, especially using specific forms like magnesium threonate and bisglycinate 1 2.

Magnesium threonate is noted for its ability to cross the blood-brain barrier and may help enhance sleep quality and depth. It's typically recommended to take magnesium threonate 30 to 60 minutes before bedtime 3 4. However, it's important to note that if you're not deficient in magnesium or if you have normal sleep patterns, additional supplementation might not be necessary 1.

For older adults or those with sleep issues potentially linked to magnesium deficiency, supplementation could provide noticeable benefits. Always consult with a healthcare provider before beginning any new supplement regimen 3.
