Verdict: Thorne Magnesium Bisglycinate leads for general wellness due to higher elemental dose and better value while Jarrow MagMind excels specifically for cognitive goals with its patented L-threonate form. Bisglycinate provides 200 mg elemental versus 144 mg in MagMind and avoids the premium pricing of the brain-focused option. Both are well-regarded chelated forms with minimal side effects compared to oxide versions.

Winner: Thorne Magnesium Bisglycinate

Thorne Magnesium Bisglycinate: 8/10

Jarrow MagMind Magtein: 7.5/10
