This star is on the map because the show intends to take the question apart properly — the trials, how it is actually tested, whether the thing sold is the thing studied. That work is not done yet, and nothing here should be read as a conclusion. When the investigation is published it will appear on this page.
What we are reading
Gathered for the investigation and not yet written up. Each note says what the paper does and does not show.
34 double-blind placebo-controlled trials, 2028 adults, in Hypertension. Median 368 mg/day for three months lowered systolic BP by 2.00 mmHg and diastolic by 1.78 mmHg. Real, replicated, and SMALL — roughly a tenth of what a first-line antihypertensive does, which is the honest way to present it rather than as either useless or a substitute. One author is at the Center for Magnesium Education and Research, worth noting. The authors themselves flag residual heterogeneity and call for better trials.
