Q. I've heard that vitamin K is good for strong bones. Should I take a supplement?
A. No. If you eat fruits and vegetables, especially cruciferous vegetables, such as broccoli and cauliflower, you’ll get enough vitamin K in your diet. Spinach and strawberries are also good sources. Since vitamin K affects blood clotting, definitely check with your doctor first before supplementing, especially if you’re on blood-thinning medication, such as coumadin.
