Lutein
The short version
A natural xanthophyll carotenoid from marigold petals — clean-label yellow and the dominant macular-pigment supplement.
It's widely considered safe at the amounts used in food, so we mark it green. The Safety section below has the details.
Where it comes from
Industrially extracted from marigold (Tagetes erecta) petals; also from spinach, kale, and other leafy greens. The dominant xanthophyll in the human macula, where dietary lutein concentrates and is hypothesized to protect against age-related macular degeneration.
How it's used
Used as a clean-label natural yellow colorant in dairy products, soft drinks, and infant formula. Also fed to chickens to deepen the yolk yellow (the consumer 'free-range egg' appearance). Sold as a supplement targeting eye-health markets.
Safety profile
ADI of 0–2 mg/kg body weight (EFSA 2010 re-evaluation, for the additive form). Supplemental use has a longer safety history with no documented adverse effects at typical intake. Unlike canthaxanthin, no retinopathy concerns at any realistic dose.
Physical & chemical properties
Yellow to orange-yellow powder or oily dispersion. Insoluble in water; soluble in fats and oils. Sensitive to light and oxygen.
Regulation worldwide
Permitted globally without restrictive limits. Approved as both a colorant additive and a nutritional ingredient.
