Vitamin D... America's Single, Deadliest Deficiency...

Nine out of 10 Americans are deficient in vitamin D... the sunshine vitamin. And surprisingly, even people that spend plenty of time in the sun can still lack this vital inflammation fighter.

This is dangerous because inflammation is a major cause of heart and brain problems... high blood pressure... joint pain... bone loss... digestive problems... blood sugar imbalances and a host of other serious health problems.
