MacuShield® began as a single product, MacuShield® Original, a dietary supplement derived from the marigold flower (Tagetes Erecta) that combines the three macular carotenoids: Meso-zeaxanthin, Lutein and Zeaxanthin.
We get these three nutrients exclusively from our diet, the Lutein and Zeaxanthin coming from dark green leafy vegetables and brightly coloured fruits, and the Meso-zeaxanthin coming from some types of fish and seafood.
Carotenoids – Carotenoids are naturally occurring plant pigments found in nature. Over 700 carotenoids have been identified to date, which include the carotenoids lutein, zeaxanthin and meso-zeaxanthin.
Lutein – A natural carotenoid entirely of dietary origin, which accumulates at the macula at the back of the eye. Lutein is most commonly found in dark green, leafy vegetables such as spinach, kale or peas.
Macula – It is the central and most sensitive part of the retina. The carotenoids luten, zeaxanthin and meso-zeaxanthin can be found at the macula.
Macular Pigment – The dietary carotenoids lutein, zeaxanthin and meso-zeaxanthin accumulate at the macula where they are collectively known as macular pigment.
