What happened
Vanadyl sulfate oxidises reactive cysteines in protein-folding enzymes and triggers cell death only in senescent cells. In old male mice, 90 days in the drinking water improved muscle endurance, lowered visceral fat, reversed liver and kidney decline, and lengthened median post-treatment lifespan by about 17% (+65.5 days).
The authors propose intermittent dosing — 2 to 4 weeks followed by months of rest — not continuous daily use.
Why it matters
Senolytics are the most watched idea in longevity, and a cheap mineral that works this way in mice is a striking result. But mice are not people, and vanadium has a narrow therapeutic window: chronic excess can damage lung and kidney.
What comes next
The next step would be safety work in people, at a dose far below the mouse equivalent of about 290–330 mg a day in an adult. Until then, this is a laboratory result, not a supplement recommendation.
PRECLINICAL — mice and human cells in vitro, no data in people. Vanadium has a narrow therapeutic window: chronic excess can damage lung and kidney. Do not present this as a supplement to take; the authors propose intermittent dosing, not continuous daily use.
