Lutein, Omega-3 (2008) & Macular Degeneration
Learn more about macular degeneration.
Researchers studied the ability of lutein and omega-3 (DHA) to enhance macular pigments to protect against macular degeneration and other macular conditions.
The study was a four month, placebo-controlled study involving nearly 50 women who were given either placebo, DHA, lutein, or lutein plus DHA. They chose these nutrients because DHA is found in the healthy retina and lutein is found in the healthy maculas.
The dosages of lutein (12 mg/day) and DHA (800 mg/day) were evaluated for their effect on levels in blood plasma and in the optical density of the macular pigment.
Both supplements alone helped to increase their concentration levels in the eye. Both lutein and DHA together displayed a synergistic benefit with the greatest difference on serum concentrations and pigment density when taken together.

Editor's note: this earlier study has been validated by others; but other carotenoids zeaxanthan and meso-zeaxanthin are also very important to protect the macula.
