Which Magnesium for Sleep

For improving sleep, the most beneficial forms of magnesium, as discussed by Andrew Huberman on the Huberman Lab, are Magnesium Threonate and Magnesium Bisglycinate:

1. Magnesium Threonate:

   • Advantages: It effectively crosses the blood-brain barrier and promotes sleep depth and reduces the time to fall asleep by engaging the GABA pathway, which has a calming effect on the brain 1 2.
   • Usage: Recommended to be taken 30 to 60 minutes before sleep 3.

2. Magnesium Bisglycinate:

   • Similar benefits to magnesium threonate regarding sleep quality. It also has the capacity to cross the blood-brain barrier effectively 4 5.

3. Other Forms:

   • Magnesium Citrate: Primarily acts as a laxative and not recommended for sleep enhancement 1.
   • Magnesium Malate: Often used for muscle recovery, not recommended for sleep since it primarily targets peripheral tissues 2.

Summary

Both Magnesium Threonate and Magnesium Bisglycinate are excellent choices for promoting sleep. They support the transition to sleep effectively without the side effects often associated with melatonin. However, individual responses may vary, so it's advisable to consult with a healthcare provider before starting any new supplement regimen.
