CHARACTERISTICS OF ZEAXANTHIN
What is zeaxanthin?
Zeaxanthin is a yellowish soluble pigment that appears in algae, bacteria and higher plants. It belongs to the group of carotenoids, which are a type of flavonoids.
Zeaxanthin function in plants is to protect the plant against solar radiation. This same property is effective to protect the human retina of the sun’s ultraviolet radiation. Zeaxanthin is a pigment that appears in a natural way in the retina, together with lutein.
Zeaxanthin acts with lutein in the sight protection. These components are in the macula, the central region of the retina, to which they give it its yellowing, but, while zeaxanthin is in the center of the macula, lutein occupies the sides.
The conservation of this pigment is what allows filtering the sun’s ultraviolet rays, preventing the formation of many diseases, including macular degeneration or vision loss, which is a disorder characterized by loss of visual acuity, as consequence of degeneration that occurs in the macula. Similarly it has been shown that high levels of these components in the eye retina defend against cataracts. Both pigments appear to also protect the body against the development of certain cancers.
