Scientific research shows that these three nutrients are found at the back of the eye, at the macula, where they form the macula pigment (yellow colour).

Meso- zeaxanthin is particularly concentrated at the centre of this pigment.

MacuShield is a lutein (10mg), zeaxanthin (2mg) and meso- zeaxanthin (10mg) once-a-day, easy to take, food supplement which combines all three macula carotenoids in a formula developed in collaboration with leading eye health experts.
