Here’s a quick do-it-yourself way to tell if YOU might need more Vitamin D… It’s from nutritionist Karen Langston, from the National Association of Nutrition Professionals: Press your fingers against your sternum – AKA your breastbone… or press on your shinbone. If it’s painful, you might be low on “D”. Why would it hurt? Because we need D for strong bones!
So if you try the sternum test and it hurts, talk to your doctor about taking a supplement.
