Vitamin K for vision

Healthy vision depends on proper circulation in the eye. Matrix Gla-protein (MGP) helps prevent calcium buildup in blood vessels and arteries (vascular buildup), promoting good circulation. But MGP needs adequate levels of vitamin K to become activated.

In this study, doctors measured vitamin K levels in 935 men and women and followed up 11 years later.

Those with the highest levels of vitamin K also had the greatest levels of activated MGP.  Doctors also saw that those with the highest levels of inactive MGP were most likely to have smaller vascular diameter in the retina of the eye, reducing circulation.
