Verdict: Thorne Magnesium Bisglycinate wins overall for most users seeking general magnesium support with higher elemental dose and better value. Jarrow MagMind excels specifically for cognitive applications where L-threonate's ability to raise brain magnesium levels has been demonstrated in studies. The 56 mg higher elemental magnesium in Thorne per serving and lower cost make it the stronger daily choice unless brain health is the primary goal.

Winner: Thorne Magnesium Bisglycinate

Jarrow Formulas MagMind Magtein: 7.5/10
