STRUCTURE AND FUNCTION
Lutein, Meso-Zeaxanthin and Zeaxanthin are a special class of higher plant carotenoids known as xanthophylls. These molecules serve as photoprotectants for the plants and leaves under environmental stress. In primates, these molecules are specifically taken up by the macula of the eye. These antioxidants serve as singlet-oxygen quenchers, helping to minimize free radical damage generated by the exposure of the lens to oxygen and light.*
Lutein and Zeaxanthin are yellow pigments that provide color in marigolds and corn, respectively. The yellow color of the macular carotenoids is crucial for the absorption of blue light. Blue light contains a shorter wavelength in the visual spectrum, consequently delivering high energy to photosensitizers in the eye.
The natural functions of carotenoids are dependant on the individual physical and chemical structures of the molecules. Most carotenoids are commonly found in membranes, and some may only efficiently scavenge free radicals generated in the inner membrane. Lutein and Zeaxanthin, however, contain hydroxyl groups that interact with the polar head groups of phospholipids, locking the molecules in a position that spans the membrane. This property allows these molecules to react with free radicals generated in both aqueous and membrane phases, which broadens their antioxidant capabilities.*
Meso-Zeaxanthin is a third carotenoid found in the macula. Unlike the more familiar Lutein and Zeaxanthin, Meso-Zeaxanthin is not commonly present in the diet, making supplementation the only practical source outside of the body.
MesoVision is a proprietary blend of carotenoids, which provides antioxidant support for the eye. MesoVision may be a desirable dietary supplement for those who wish to nutritionally support visual acuity and macular health.*
HOW CLIENTS MAY BENEFIT
Supports eye health.*
Helps absorb high-energy blue light in the macula.*
Provides antioxidant support for the retina and macula.*
Promotes visual acuity.*
One study found that oral supplementation with 10 mg Lutein per day for 12 weeks significantly promoted macular density.
A multi-center study investigating the association between carotenoids and eye health found that mature adults who ate more dark green leafy vegetables had 43% better support of macular health. Among specific carotenoids, Lutein and Zeaxanthin were most strongly associated with macular support.
