Anticancer effect
Lutein has unique biological efficacy in inhibiting tumor growth, the mechanisms of which mainly include antioxidant activity, inhibition of tumor vascular proliferation and cell proliferation, and so on.
Role of delayed early arteriosclerosis
The latest findings found that lutein can slow the development of early arteriosclerosis. After animal testing, it was found that the animals fed lutein and mouse chow, stirred together, and fed, had a lower incidence of arterial thrombosis than those not fed the diet containing lutein.
Role in diabetes prevention
