The difference between good and declining cognitive performance as we age might come down to something surprisingly basic: Two essential minerals in your blood.
New research published in the journal Nutrients reveals that lower levels of calcium and magnesium may link to worse cognitive performance in adults over age 60. But while both minerals matter, their relationship isn’t equal. People with healthy magnesium but low calcium levels showed significant cognitive decline, while those with low magnesium but normal calcium didn’t have as much difficulty.
“Among the groups, those with low calcium alone had the lowest scores on the cognitive tests,” explains Catherine Gervacio, a registered nutritionist. “This suggests calcium might have a stronger individual link to cognitive health than magnesium. It’s particularly striking since many studies emphasize magnesium’s role in brain health.”
The study marks the first time researchers have measured these minerals directly in blood rather than relying on dietary questionnaires, lending new weight to their findings.
While experts recommend getting these nutrients from food where possible, supplements might benefit those who can’t maintain adequate levels through diet alone. If you’re looking for a good calcium-magnesium supplement, MNT’s product testers recently selected Thorne Women’s Multi 50+ as their top pick.
For expert guidance on optimal intake, food sources, and supplement recommendations for brain health, jump to “Low calcium, magnesium levels tied to poorer cognitive performance.”
