Research suggests lutein plays a significant role in human health.  For cardiovascular health,  lutein present in blood serum may favorably impact arterial wall thickening, a component of atherosclerosis.**

At least one published study produced findings that suggested higher levels of lutein in the serum may be linked with less thickening of arterials walls.† **

Also, read a technical summary of The Los Angeles Atherosclerosis Study, focusing on the effect of lutein on the progression of atherosclerosis.**
