Lutein, zeaxanthin and meso-zeaxanthin for eye health
by Newsletter Editor
Meso-zeaxanthin is the yellow pigment in the eye that contains lutein and zeaxanthin. Doctors wanted to achieve the highest combined concentrations of these carotenoids in 27 volunteers with normal vision and 27 with AMD, and tested three dosage levels of lutein and meso-zeaxanthin.
All three groups took 2 mg of zeaxanthin per day. Group one also took 20 mg of lutein; group two 10 mg, and group three 3 mg of lutein. Group one took no meso-zeaxanthin; group two 10 mg, and group three 17 mg of meso-zeaxanthin per day.
After eight weeks, circulating levels of meso-zeaxanthin had increased in all three groups, while group two had the highest combined concentrations of all three carotenoids.
