Lutein and zeaxanthin
What lutein and zeaxanthin are, where they come from, how much supplements contain and how to read the label of eye complexes.
This substance has no health claim authorised in the European Union. So we describe what it is and how it is taken, but do not say what it does in the body.
What they are
Lutein and zeaxanthin are yellow pigments of the carotenoid family. Food supplies them through spinach, kale, broccoli, corn and egg yolk. For supplements they usually come from marigold flowers (Tagetes erecta).
Lutein and zeaxanthin themselves have no authorised health claims in the European Union. Eye complexes often pair them with vitamin A, riboflavin and zinc — these do have authorised claims about maintaining normal vision, shown on the product page when the dose is enough.
How to read the label
A usual supplement dose is 10–20 mg of lutein and 2–4 mg of zeaxanthin a day. Meso-zeaxanthin is the group's third carotenoid, added to some formulas. Lutein is fat-soluble, so it is often made as oil-filled softgels.
How they are taken
Take as the pack directs, with a meal containing fat. Smokers should check complexes' contents: high doses of beta-carotene are not recommended for them. If your eyesight troubles you, see an eye doctor — a supplement does not replace an examination.
