Vitamin K and memory in heart disease
Part of Heart & circulation clinical trials.
This study looks at whether a diet low in vitamin K affects thinking and memory in people with heart disease. It may help show if adding vitamin K could improve brain health.
Summary written for real people, not researchers, by Clin2.
