Myth-buster
Anthocyanins didn’t improve blood vessel function in several trials — a systematic review reveals inconsistent results.
This matters because while anthocyanins are often touted for heart health, the evidence is patchy: some studies see a benefit, others don't, and this review is one of the first to chart the inconsistency, so the picture is far from settled.
A systematic review of anthocyanin-rich foods and extracts found that while some studies showed improved flow-mediated dilation (a marker of vascular health), others found no significant effect. The results are mixed, meaning anthocyanins may not reliably improve blood vessel function for everyone. Because this is an early review, more research is needed to understand when and for whom they work.
Where this fits in the evidence
This is among the first studies we've indexed on Anthocyanins for Improved Flow-Mediated Dilation — treat it as an early signal until more research accumulates.
