THE SCIENCE BEHIND MACUSHIELD™
Good nutrition goes hand-in-hand with overall health and wellbeing*, but certain nutrients are found in high concentrations in the eye, such as lutein, meso-zeaxanthin and zeaxanthin.

The 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.

The macula

The macula is part of the retina – an area at the back of your eye that is responsible for our central vision. The macula gives us sharp and detailed vision at the centre of your eye-line, which is essential for activities like reading and driving.

Macular carotenoids

The macula is the most sensitive part of the retina, and has a very high concentration of light-sensitive cells which help to give us this detailed central vision. The body naturally deposits the macular carotenoids at the macula.

Macular pigment

This is called the macular pigment, and looks like a yellow spot at the back of the eye. The three macular carotenoids are lutein, zeaxanthin and meso-zeaxanthin. Meso-zeaxanthin is particularly concentrated at the centre of this pigment.

Nutrition for your macula

Macular carotenoids are found in high concentrations at the back of the eye, in the macula. Learn more about nutrition for your macula in this short video.

Sources of macular carotenoids

The body can’t make macular carotenoids, so we have to consume them in our diet. An average western diet contains approximately 1.3-3mg of these carotenoids each day.

Lutein

Lutein is found in dark green leafy vegetables – like spinach and kale – as well as in corn and eggs.

Meso-zeaxanthin

Meso-zeaxanthin is found mainly in fish products, specifically the skin of salmon, sardine, and trout.

Zeaxanthin

Zeaxanthin, like lutein, is found in dark green leafy vegetables, as well as in sweetcorn and eggs.

Did you know?

Every MacuShield product contains all three macular carotenoids, providing 10mg of lutein, 10mg of meso-zeaxanthin and 2mg of zeaxanthin per day. This formula of macular carotenoids has been developed in collaboration with leading eye experts. The macular carotenoids in MacuShield are obtained from marigolds (Tagetes Erecta), specifically grown for this purpose. MacuShield products are nutritional supplements and should not replace a balanced diet.
