How many studies support Magnesium?

Multiple independent meta-analyses of randomized trials, spanning from 2002 to 2025, consistently find magnesium supplementation produces a small but real reduction in blood pressure, with effects present across general and diabetic populations. That's backed by 10 published studies in Vitaebase's database, including 10 meta-analyses, the most recent from 2025 -- a fairly substantial body of research for a single topic.
