Vitamin D--could be too much
Stephanie Desmon, Johns Hopkins Medicine, Jan 23, 2012, says Vitamin D—so lauded these days for bone health and also heart protection--can cause harm if above the low end of normal.
Increasing levels of Vitamin D in the blood are linked with lower levels of a popular marker for cardio inflammation—c-reactive protein or CRP. That sounds good—but for adults without cardio symptoms but with relatively low Vit D levels, lower levels of inflammation were found.
This led them to say that higher levels of Vit D did not curtail inflammation more. This appears in the Jan 15th American J of Cardiology.
Be sure the supplement is indicated for you. And—I would add—make sure your doctor knows about these findings.
