According to 2024 research, a standard 400mg magnesium dose can deliver therapeutic amounts of bound compounds effectively, regardless of the specific salt formulation used. This finding emerged from Chen and colleagues’ meta-analysis examining cognitive outcomes across different magnesium types.
The research directly challenges marketing claims that specialized forms like magnesium L-threonate offer superior brain health benefits compared to basic formulations. Data analysis showed that total magnesium intake—not the delivery method—correlates with improved global cognition and working memory function.
Brain imaging analysis from the UK Biobank further supports this conclusion, revealing consistent associations between magnesium consumption and preserved brain volume in memory-critical regions. The protective effects showed no salt-specific advantages, suggesting that consistent intake of any bioavailable magnesium form at therapeutic doses provides comparable long-term cognitive protection.
