The MP is made up of two pigments or carotenoids, which are phytochemicals found in plants.

The two main carotenoids are lutein and zeaxanthin.

They are responsible for protecting the eye from the harmful effects of free radicals and for protecting the eye from the damaging effects of blue light.

Lutein is the main carotenoid in the peripheral retina, making up 67% or greater of the MP.

Zeaxanthin is the main carotenoid in the central macula making up to 75% of the MP.

Increasing the concentration of these pigments in the eye may help prevent age-related macular degeneration or slow the progression of age related macular degeneration.

MP can be increased with diet and/or dietary supplements of lutein and zeaxanthin. The body cannot make these carotenoids.

Macular Pigment Density Studies

Currently there are several studies researching supplementation and its effect on MP.

1. Enhancement of Macular Pigment Density by Oral Lutein Supplementation (EMPOLS)

The purpose of this study in Berne, Switzerland is to determine if there is an increase in MP density after six months supplementation of Lutein 10 mg daily, contained in VitaluxPlus.

2. The Role of Macular Pigment in Patients With Age-Related Macular Degeneration

This is an observation study in Berne, Switzerland, with the aim of assessing "the peak MP density as well as the MP distribution in relation to the risk for ARMD."

In this study they hope to:

1. Assess the relationship of MP density with the occurrence of age related macular degeneration

2. Identify patients with low MP density

3. Improve the early diagnosis of patients at high risk for developing ARMD

4. Develop a basis for dietary supplementation of lutein and/or zeaxanthin in patients with high risk for ARMD due to low MP values

Foods High in Lutein

Foods like corn, eggs, and spinach all contain lutein. Carrots, cantaloupe, oranges, red and orange peppers, kale and collard greens are also rich in lutein.

Lutein is a fat-soluble substance, so it is important to eat some healthy fat with your raw vegetables, such as olive oil, for proper absorption.
