Vitamin E for Friedreich ataxia? A meta-analysis of 7 trials found no benefit on ataxia scores after 12 months — and the same went for other drugs tested.
This null result challenges the common assumption that vitamin E can slow or reverse ataxia in Friedreich's disease, but the evidence is moderate-certainty and based on only 513 participants across seven studies — so the picture is contested, not settled.
Researchers pooled data from seven randomized trials (513 participants) and found that pharmacological treatments — including vitamin E — produced essentially no change in ataxia severity after a year compared to placebo. The same analysis also found no improvement in heart wall thickness, daily living activities, or exercise capacity, suggesting the lack of effect was consistent across multiple measures.
Where this fits in the evidence
This is among the first studies we've indexed on Vitamin E for Improved Ataxia Rating Scale Score — treat it as an early signal until more research accumulates.
