Register to receive a free 6-day sample of MacuShield Eye Health Supplements. MacuShield was first manufactured in 2006 following the results of some interesting research into the role of three nutrients, Meso-zeaxanthin, Lutein and Zeaxanthin. It was on this fact that the brand proudly states our slogan "Trust The Science". That ethos of research still continues today and we continue to invest in both the safety and stability trials on the product to ensure the underlying safety of the product and also in new areas of potential for these nutrients.
