Vitamin K and thinking skills in older adults with heart disease
Part of Heart & circulation clinical trials.
This study tests whether a vitamin K supplement (phylloquinone) can help protect thinking and memory in older adults with coronary heart disease who have low vitamin K intake. It may be a good fit if you are 60+, have stable heart disease, and don't take vitamin K supplements.
