lutein
Lutein is a technical term used primarily in nutritional science, ophthalmology, and biochemistry. It carries a neutral, clinical connotation and is most frequently encountered in the context of dietary supplements, eye health discussions, and botanical studies regarding carotenoids.
As a chemical compound and a specific nutrient, it is treated as an uncountable mass noun. It does not have a plural form in standard usage; one refers to the presence or concentration of lutein rather than multiple units of it.
