What this trial studies

This clinical trial investigates the effects of vitamin K2 and zinc supplementation on skeletal muscle and neurological function in patients who have recently experienced an ischemic stroke. Participants will receive either vitamin K2, zinc, or a placebo daily for two years, with regular assessments of muscle strength, muscle mass, and neurological function. The study aims to determine if these supplements can enhance recovery and improve overall health outcomes for stroke patients. Follow-up will continue for an additional year to evaluate long-term effects.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have experienced a recent ischemic stroke without significant residual limb paralysis.

Not a fit: Patients with consciousness disorders, severe swallowing difficulties, or those diagnosed with cerebral hemorrhage will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved recovery and quality of life for patients who have suffered an ischemic stroke.

How similar studies have performed: While the specific combination of vitamin K2 and zinc for stroke recovery is novel, previous studies have shown that nutritional interventions can positively impact recovery in stroke patients.
