Depends: Vitamin d intake depends on your blood level. Some people need more than others; their body breaks it down faster. It will not have any effect on bruising. Vitamin k is in leafy green vegetables which you should be eating daily. Vitamin k is also in many multivitamins. Vitamin k deficiency is very rare unless you have unusual medical problems so look for other causes of bruising. See your doctor.
