Comment: Lutein is a carotenoid that derives from plants including Eupatorium cannabinum (hemp agrimony), Hibiscus syriacus (rose of Sharon) and green leafy vegetables such as spinach and kale. It is a commercially used food additive and dietary supplement.
In humans ingested lutein is accumulated in the macula (central retina), where it is a component of the macular pigment (a blue light filter and antioxidant) that is important for optimal visual acuity [1]. Its use is permitted in many jurisdictions as a safe ingredient for inclusion in food supplements that claim to maintain eye health and visual performance, although clinical benefit has not been robustly established. |
