MacuShield Eye Supplements (90). MacuShield began as a single product, MacuShield Original, a dietary supplement derived from the marigold flower (Tagetes Erecta). Macushield ingredients 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.. Benefits. 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.. Meso-zeaxanthin – Meso-zeaxanthin is the most central carotenoid found at the epicentre of the macula. Meso-zeaxanthin is naturally occurring in the human food chain, found in several species of fish to date.. Oxidative Stress – Oxidative stress refers to damage by reactive, unstable molecules. These molecules, which include free radicals, are produced naturally in the body through oxygen metabolism.. Retina – The retina is the light-sensitive layer of tissue at the back of the inner eye. It acts like the film in a camera; images come through the eyes’ lens and are focused on the retina. The retina then converts these images to electric signals and sends them via the optic nerve to the brain.. Zeaxanthin – A natural carotenoid entirely of dietary origin, which accumulates at the macula at the back of the eye. Zeaxanthin is commonly found in brightly coloured fruit and vegetables such as peppers and sweetcorn.. You may check out our customers Macushield Reviews below.
