What is Meso-Zeaxanthin?

Similarly to Lutein and Zeaxanthin, Meso-Zeaxanthin (MEE-so zee-ah-ZAN-thin) is a yellowish carotenoid, which has powerful antioxidant qualities and an ability to filter harmful visible blue light, however unlike Lutein and Zeaxanthin it is not found in plants and is therefore not part of our normal everyday diet.

Meso-Zeaxanthin is also the third carotenoid present in the retina and together with Lutein and Zeaxanthin they form the macular pigment. Of the 700 carotenoids present in nature only these three specific carotenoids gather in the macula. Furthermore Meso-Zeaxanthin is not present anywhere else in the body and can only found in this highly targeted point, right at the very centre of the macula where vision is at its sharpest.

Key Benefits

Recent research has suggested that the antioxidant potential of the macular pigment and its ability to neutralise harmful free radicals is greatly enhanced when Meso-Zeaxanthin is present.

Furthermore, studies have shown that the visual benefits were better amongst those with a diet rich in all three macular carotenoids including Meso-Zeaxanthin, as opposed to those who were only consuming Lutein and Zeaxanthin and therefore lacked this key centrally dominant carotenoid.

Where can I find it organically?

Up until very recently it was thought that Meso-Zeaxanthin was exclusively derived from the breakdown of Lutein within the retina, concluding that a deficiency of Meso-Zeaxanthin within the macula was caused by an individual’s inability to make this conversion. Current research however is now calling this into question suggesting that Meso-Zeaxanthin can also be found a number of marine organisms including shrimp and sea turtles and appears to be particularly concentrated in the skin of specific fish, such as trout and salmon.

Studies are currently underway to quantify the exact levels of Meso-Zeaxanthin in more food types, although to date Meso-Zeaxanthin has only been detected in very specific foods, that are by no means part of a typical diet, moreover the quantities found have been very small.

How does Macu-STRENGTHTM help?

Based on research it would appear that, as Meso-Zeaxanthin is not a compound generally found in our everyday diet or indeed in the quantities that are needed to be of benefit to eye health, diet alone is not an option.

Macu-STRENGTHTM contains 10mg Meso-Zeaxanthin in combination with 10mg Lutein and 2mg Zeaxanthin, which most leading experts in the field of eye science believe to be the optimum quantities needed to fully supplement the macular carotenoids.
