The chemical formulas for both, zeaxanthin and lutein are incredibly similar which is why they are known to have the same effects on the human body. The human retina is said to benefit from the consumption of a diet that is rich in zeaxanthin.

There have been studies conducted in an attempt to understand the effect of zeaxanthin on the human body. They have revealed a relationship between zeaxanthin and an overall reduction in the occurrence of some of the eye diseases including macular degeneration that is related to age.

The progression of this disease is said to decrease significantly with the introduction of zeaxanthin in the dietary schedule. However, since all the supplements introduced during the studies included both zeaxanthin and lutein, the differentiation between their effects was deemed difficult. Therefore, experts have suggested using a disclaimer when trying to sell supplements containing lutein and zeaxanthin.

The approved dosage for zeaxanthin is 0.75mg/kg.
