Can magnesium citrate be used as a supplement for sleep

Andrew Huberman advises against using Magnesium Citrate as a sleep aid due to its strong laxative effect. He emphasizes that it is not effective in promoting sleep. Instead, he recommends using forms like Magnesium Threonate or Magnesium Bisglycinate, which are better suited for sleep as they can cross the blood-brain barrier and engage the GABA pathway, promoting relaxation and deeper sleep 1 2.
