Lutein and zeaxanthin: what they do for eyes, from premature babies to aging adults

Lutein is sold as an everyday eye supplement, and the EU authorized none of the 17 claims made for it. Its clearest result is in premature babies, where a Cochrane review pooling 4 trials in 532 infants found it probably halves severe retinopathy of prematurity, while in adults with macular degeneration the effect is small and rests on low-certainty evidence.

How much you need

• Mature raw spinach averages about 7.5 mg of lutein per 3.5 oz (100 g) and raw kale about 6.3 mg of lutein plus zeaxanthin, while one large egg yolk sample averages 0.6 mg per 3.5 oz (100 g) with a wide spread. — USDA Foundation Foods samples Evidence E source
• In an uncontrolled 4-week study in 19 Japanese men with high cholesterol, adding one soft-boiled egg a day raised serum lutein plus zeaxanthin above baseline without raising LDL. — 19 moderately hypercholesterolemic Japanese men, 4 weeks Evidence C source

How well your body absorbs it

• In a crossover trial in 16 young men, adding 3 scrambled eggs to a raw vegetable salad raised lutein and zeaxanthin absorption 4- to 5-fold. — 16 healthy young men, single test meals, 10 h sampling Evidence B source
• In a crossover trial in 16 people, salad eaten with olive oil gave 55% higher carotenoid absorption than with coconut oil, and emulsified fat 40% more than non-emulsified. — 16 subjects, salad with 28 g of test fat, 10 h sampling Evidence B source
• In a crossover trial in 24 adults, 6 mg a day of marigold lutein raised serum lutein 2.4-fold within 15 days, with no difference between free and ester forms. — 24 healthy adults aged 20-35 and 50-65, two months per form Evidence B source

Who is most likely to fall short

• A Cochrane review of 5 RCTs in preterm infants found lutein plus zeaxanthin probably halves severe retinopathy of prematurity (stage 3+, 4 studies, 532 infants), with no adverse effects reported. — preterm infants under 37 weeks, 5 RCTs (666 infants) in the review, 4 RCTs (532 infants) for ROP stage 3+ Evidence A source

What the evidence does and does not show

• A Cochrane review found lutein/zeaxanthin alone gave similar or slightly lower risk of progression to late macular degeneration than control (RR 0.94), on low-certainty evidence from 4,176 people. — people with AMD, mostly AREDS2, 4,176 participants Evidence A source
• In 10-year AREDS2 follow-up of 3,882 people, lutein/zeaxanthin lowered progression to late AMD by 15% versus beta-carotene and did not significantly raise lung cancer odds, unlike beta-carotene. — 3,882 participants with intermediate AMD, mean age 72, 10 years Evidence B source
• In 8 RCTs of 1,176 people with macular degeneration, lutein and zeaxanthin improved visual acuity by 0.04 logMAR, with about 0.003 logMAR more per extra mg a day. — 1,176 AMD patients, 8 RCTs Evidence A source
• A systematic review of 6 RCTs in 584 people with dry eye found 3 to 20 mg a day of lutein gave mixed results, too varied to pool. — 584 subjects with dry eye disease, 6 RCTs, 4 to 12 weeks Evidence A source
• An umbrella review of 24 meta-analyses links higher dietary lutein to lower risk of macular degeneration, cataract, heart disease and stroke, on observational data. — 24 meta-analyses covering 29 outcomes Evidence C source
• The EU did not authorize claims that lutein promotes healthy eye function, protects the retina from oxidation or filters blue light, and none of 17 lutein claims in the snapshot were authorized. — EU claims register, claim POL-HC-7520 Evidence E source

What too much does

• A 2012 Veterans Affairs review notes lutein has been linked to harmless yellowing of the skin in two trials at 15 mg a day for 4 to 5 months. — adults in supplement trials Evidence E source

What to do with this

Leafy greens are the richest food source. USDA samples of raw mature spinach average about 7.5 mg of lutein per 3.5 oz (100 g), and raw kale about 6.3 mg of lutein plus zeaxanthin, from only three samples. Egg yolk is far lower at about 0.6 mg per 3.5 oz (100 g), with a wide spread between samples.

Eat the greens with some fat. In 16 young men, adding three scrambled eggs to a raw vegetable salad raised lutein and zeaxanthin absorption 4- to 5-fold over a single meal, though eggs carry some lutein of their own. In another 16 people, salad with olive oil gave 55 percent higher total carotenoid absorption than with coconut oil.

If you have intermediate macular degeneration, the AREDS2 formula is a conversation for your eye doctor. Over 10 years in 3,882 people, the version with lutein and zeaxanthin cut progression to late disease by 15 percent compared with the version containing beta-carotene, and it did not significantly raise lung cancer odds the way beta-carotene did.

For dry eye, the trials were too mixed to give a clear reason to buy a capsule, and the EU did not authorize the claim that lutein promotes healthy eye function. For a premature baby, whether lutein is given is a decision for the neonatal team.

Where to get it from food

USDA does not report lutein and zeaxanthin for individual foods, so this site cannot rank foods by it. The sections above name the foods the studies themselves looked at.

The bottom line

The strongest lutein evidence comes from neonatal wards. Severe retinopathy of prematurity fell by about half (relative risk 0.49), at moderate certainty, in 4 trials with 532 infants from Italy and the United States only. Retinopathy of any stage and deaths did not differ significantly. In adults with macular degeneration a Cochrane review resting almost entirely on AREDS2 found lutein and zeaxanthin may give similar or slightly lower risk of late disease than control (relative risk 0.94, 95% CI 0.87 to 1.01). Nearly everyone in that trial also took the AREDS vitamin formula. Across 8 trials in 1,176 patients, visual acuity improved by 0.04 logMAR, roughly two letters on an eye chart. For dry eye, 6 trials using 3 to 20 mg a day gave results too mixed to pool. Observational data link higher dietary lutein to lower rates of macular degeneration, cataract, heart disease and stroke, and an association is all they can show. The documented side effect is cosmetic, a harmless yellowing of the skin in two trials at 15 mg a day for 4 to 5 months, with no frequency given. The preterm trials reported no adverse effects. We have no card on lutein supplements in pregnancy or alongside medicines, and that is a gap in what we hold.
