Polyphenol-rich Salicornia plus B vitamins to slow cognitive decline after lacunar stroke

A Multicenter Randomized Clinical Trial Compared With Standard Clinical Practice to Evaluate the Efficacy of a Polyphenol-rich Salicornia Extract in the Progression of Cognitive Decline in a Cohort of Patients With Lacunar Infarcts

Not applicable Interventional Fundación Pública Andaluza para la gestión de la Investigación en Sevilla · NCT07353424

This will test whether a Salicornia-derived polyphenol supplement combined with B vitamins can slow thinking and memory decline in people who had a lacunar stroke within the past year.

What this trial studies

SALACUNAR is a multicenter randomized controlled trial comparing a polyphenol-rich Salicornia extract plus B vitamins (B-salicornia) to standard clinical care in patients with lacunar infarcts. Three hundred patients aged 40–90 with MRI-confirmed lacunar stroke within the previous year and an mRS ≤3 will be randomized to receive the supplement or usual care. Primary outcomes include change in cognitive performance measured by the MOCA scale and biochemical markers such as homocysteine, with the sample size powered to detect a two-point MOCA difference. The supplement has shown prior safety and preliminary benefits on homocysteine and MOCA in smaller studies, and participants will attend site visits for follow-up.

Who should consider this trial

Good fit: Ideal candidates are adults 40–90 with an MRI-confirmed lacunar infarct within the past year, an mRS of 3 or less, able to swallow capsules, not currently taking vitamin or polyphenol supplements, and with expected life expectancy over 12 months.

Not a fit: Patients with severe disability (mRS >3), active cancer, dysphagia, allergies to halophytes, hyperthyroidism, current pregnancy or breastfeeding, recent use of vitamin/polyphenol supplements, or participation in another study are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If effective, the supplement could slow cognitive decline after lacunar stroke and help preserve daily functioning.

How similar studies have performed: Small prior studies reported good safety and improvements in homocysteine levels and MOCA scores with similar Salicornia-based supplements, but large randomized trials are limited.
