Surprising
Vitamin D supplements improved leg function after stroke – but the meta-analysis leans on only 123 patients, all from unblinded trials.
With just 123 participants and no blinding, this early evidence hints at a potential benefit for stroke rehabilitation, but the picture is far from settled – larger, rigorous trials are needed before drawing conclusions.
Researchers pooled data from small studies and found that stroke survivors who took vitamin D showed better recovery of lower extremity movement and lower disability scores. However, the studies were not placebo-controlled, and the specific dose of vitamin D used was not reported.
Where this fits in the evidence
This is among the first studies we've indexed on Vitamin D for Improved Functional Ambulation Classification — treat it as an early signal until more research accumulates.
