What magnesium is best for sleep

For sleep improvement, Andrew Huberman recommends Magnesium Threonate (also referred to as magnesium 3 and 8) and Magnesium Bisglycinate. These forms have been identified as highly bioavailable and particularly effective in engaging the GABA pathway in the brain, which is crucial for transitioning to sleep. Magnesium Threonate is noted for its ability to be preferentially shuttled to the brain, supporting deeper and more rapid onset of sleep 1.

Here is a more detailed comparison of their effects based on statements by Andrew Huberman:

• Magnesium Threonate: Known for promoting sleep depth and potentially having neuroprotective effects. It is recommended to take it 30 to 60 minutes before bedtime to enhance sleep initiation and quality 2.

• Magnesium Bisglycinate: Similar to Magnesium Threonate in terms of promoting relaxation and transitioning into sleep. It works by engaging GABA receptors in the brain, promoting the shutdown of brain activities associated with wakefulness 3.
