What is magnesium malate?

Magnesium malate is a form of magnesium that has been shown to have specific benefits for reducing delayed onset muscle soreness, which can occur after workouts, especially those involving eccentric loading or are otherwise very novel or intense 1. It is distinct from other forms of magnesium, such as magnesium threonate and magnesium bisglycinate, which are more associated with improving sleep and cognitive function 2. Andrew Huberman also references magnesium malate as effective in reducing inflammation and recovery 3, as well as being potentially beneficial for the mitochondria in gut epithelial cells 4. Though magnesium malate has been suggested to offer relief from muscle soreness and act as a form of supplementation for muscle repair, as it is preferentially shuttled to muscle rather than the brain 3. It's always advised to consult with a healthcare professional before starting any new supplement regimen.
