Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

?Limited ResearchEpsom salt baths do not meaningfully increase blood magnesium levels despite potentially relaxing muscles.

✕Not SupportedThere is no study showing that Epsom salt soaking increases plasma magnesium levels.

◐Partially SupportedAdequate magnesium intake is associated with lower vitamin D deficiency and reduced mortality risks from heart disease and colorectal cancer.

◐Partially SupportedThe initial 2016 study on magnesium L-threonate showed significant urinary magnesium excretion.

◐Partially SupportedNet absorption of dietary magnesium is about 50% and can be lower with high-fiber diets, but bioavailability from plant sources can be increased by activating phytases through methods like heating, germinating, or sprouting.

✓Well SupportedMagnesium is crucial for healthy electrolyte balance, supporting nerve impulses, muscle contraction, and heart rhythm.

✓Well SupportedIn a placebo-controlled, double-blind study, individuals with mild cognitive decline who received magnesium threonate improved their cognitive age by an average of eight years over three months.

◐Partially SupportedThe safe upper limit for daily magnesium intake from supplements is 350 mg, above which gastrointestinal side effects may occur.

◐Partially SupportedInsufficient magnesium levels may be linked to accelerated brain volume loss, potentially hastening the onset of age-related dementia.

◐Partially SupportedAcute, short-term exercise can lead to a brief spike in blood magnesium levels, called transient hypermagnesia.

◐Partially SupportedMiddle-aged adults consuming at least 196 mg/day of magnesium had a 37% lower chance of developing dementia over 17 years compared to those consuming 174 mg/day or less.

◐Partially SupportedFive randomized control trials show magnesium supplementation reduces migraine frequency and intensity.
