What magnesium helps you sleep

Magnesium threonate and magnesium bisglycinate are the forms most often recommended to support falling asleep. They may cross into the brain more readily than other forms and promote GABA activity, which can quiet brain activity involved in thinking and rumination. 1

Magnesium bisglycinate is also suggested as a sleep option; magnesium-related gastrointestinal discomfort can occur, so individual tolerance matters. 2
