Lutein is a potent antioxidant carotenoid found in abundance in fruits and green leafy vegetables. Lutein is also one of the dominant pigments found in the macular region of the retina. In the macula, lutein is selectively accumulated from plasma and filters out visible blue light. Recent studies suggest this filtering process serves to protect the retina from damage caused by light or oxidation. This lutein supplement product is extracted from the marigold flower.

Lutein supplement use and pigment density in the retina
The use of a zeaxanthin and lutein supplement leads to an increase in macular pigment optical density. In one study three subjects consumed 30 mg of lutein and 2.7 mg of zeaxanthin supplement each day for 120 days. At the two most central loci, macular pigment optical density significantly increased in all three subjects with the zeaxanthin and lutein supplement use.

Source of lutein supplement
Most of the commercially available lutein supplements are derived from the marigold plant. Manufacturing of lutein varies between different companies.

Lutein supplement research - do lutein supplements help vision?
A randomised controlled trial investigating the effect of lutein and antioxidant dietary supplementation on visual function in healthy eyes.
Clin Nutr. 2008 Apr;27(2):218-27. Bartlett HE, Eperjesi F. Ophthalmic Research Group, School of Life and Health Sciences, Aston University, Aston Triangle, Birmingham B4 7ET, UK.
It has been suggested that retinal lutein may improve visual acuity for images that are illuminated by white light. Our aim was to determine the effect of a lutein supplement and antioxidant dietary supplement on visual function. A prospective, 9- and 18-month, double-masked randomised controlled trial. For the 9-month trial, 46 healthy participants were randomised (using a random number generator) to placebo (n=25) or active (n=21) groups. Twenty-nine of these subjects went on to complete 18 months of supplementation, 15 from the placebo group, and 14 from the active group. The active group supplemented daily with 6 mg lutein combined with vitamins and minerals. Outcome measures were distance and near visual acuity, contrast sensitivity, and photostress recovery time. There were no statistically significant differences between groups for any of the outcome measures over 9 or 18 months. There was no evidence of effect of 9 or 18 months of daily supplementation with a lutein-based nutritional supplement on visual function in this group of people with healthy eyes.
   Comments: It is possible that the lutein dosage was too high. In our experience, when the dosage of lutein is too high, vision becomes worse. This may be due to an imbalance of lutein with other carotenoids in the retina, or other factors. It is possible that a daily dose of 1 or 2 mg of lutein supplements may have led to better vision, or perhaps taking the lutein supplement only 2 or 3 days a week.
