Reverse-osmosis and desalination treatment can remove roughly 90-99% of naturally occurring minerals, leaving very low-mineral ("soft") water; magnesium and calcium are the two ions that define water "hardness" and that most drinking-water health research has focused on. In the body, magnesium is a cofactor for hundreds of enzymatic reactions and, together with calcium, participates in vascular tone, blood-pressure regulation, and the electrical activity of the heart. ## Its role in longevity Observational cohort studies and meta-analyses link higher magnesium intake—including magnesium in drinking water—with lower blood pressure and reduced risk of stroke, heart failure, type-2 diabetes, and all-cause mortality, and randomized controlled trials show that magnesium supplementation modestly lowers blood pressure. No study has tested mineral drops themselves; the closest direct human trial is a 2026 double-blind RCT in adults over 50 in which daily calcium/magnesium-rich mineral water cut falls by 82% at six months and improved muscle mass over a year—though it tested bottled mineral water, not drops. Evidence on water hardness is genuinely mixed: several cohort and case-control studies report fewer fatal heart attacks and strokes with harder water, others (for example north-west England) find no association, and heterogeneity is high. Drops also deliver small mineral doses relative to dietary needs. Honest framing: a sensible way to restore minerals stripped by reverse-osmosis filtration, not a demonstrated longevity intervention. This evidence describes magnesium and calcium themselves and drinking-water mineral content in general, not this specific commercial product. ## Evidence grade: Emerging evidence - **What the grade means:** Curated grade based on the human and mechanistic evidence for this compound. - **What this grade does not say:** No human trial has tested mineral drops directly — support is extrapolated from mineral-water research, where one RCT of calcium/magnesium-rich water reduced falls in older adults. Drops typically deliver small doses relative to dietary needs. A sensible way to restore what reverse-osmosis filtration strips out, not a proven longevity intervention. ## In the news - **Magnesium and blood pressure: What's the evidence?** — Harvard Health Publishing 2022 [Read it](https://www.health.harvard.edu/heart-health/magnesium-and-blood-pressure-whats-the-evidence) > In January 2022, the FDA announced that companies can make certain health claims regarding the consumption of magnesium and a reduced risk of high blood pressure. - **Dietary magnesium associated with reduced risk of heart disease, stroke and diabetes** — EurekAlert!
