Myth-buster
Vitamin E raised eGFR by a small but significant margin in a meta-analysis of drug-induced kidney injury — but the dose is a black box and the evidence is brand-new.
This is the first meta-analysis to suggest vitamin E may protect kidney function during drug injury, but because it’s an early finding with unspecified doses, it’s a clue to watch, not a reason to supplement.
In a pooled analysis of six randomized trials, vitamin E treatment led to a modest bump in eGFR (a key measure of how well the kidneys filter waste), plus reductions in creatinine and acute kidney injury. Yet the studies didn't report the vitamin E dose used, and the overall evidence is too thin to shift clinical practice — consider this a promising signal that needs confirmation.
Where this fits in the evidence
This is among the first studies we've indexed on Vitamin E for Improved eGFR — treat it as an early signal until more research accumulates.
