Lutein + Zeaxanthin
Lutein and Zeaxanthin
Carotenoid pigments that accumulate in the eye, providing protection against blue light and age-related vision decline.
Lutein and zeaxanthin are carotenoids found in high concentrations in the macula of the eye, where they form macular pigment that filters harmful blue light and provides antioxidant protection. Strong evidence supports their role in reducing risk of age-related macular degeneration (AMD) and cataracts. Also beneficial for reducing digital eye strain.
Mechanisms of Action
Blue Light Filter
Absorbs harmful blue light before it damages retinal cells
Antioxidant Protection
Neutralizes free radicals in the eye
Recommended Dose
10mg lutein + 2mg zeaxanthin
Optimal Timing
- With a meal containing fat
Take with food
Best Form
Softgels with both lutein and zeaxanthin
Alternatives: FloraGLO lutein (most studied), Lutein esters
Free-form lutein may absorb better than lutein esters. Look for products with both lutein and zeaxanthin in ~5:1 ratio.
Duration
Minimum: 12 weeks
Optimal: 24 weeks
Cycling: Not required
Note: Fat-soluble carotenoids — absorption improves significantly with dietary fat. Can be taken any time of day.

Leermakers ET et al. • The American journal of clinical nutrition (2016)
“Our findings suggest that higher dietary intake and higher blood concentrations of lutein are generally associated with better cardiometabolic health.”
Key Findings:
- Meta-analysis showed a lower risk of coronary heart disease (pooled RR: 0.88; 95% CI: 0.80, 0.98) and stroke (pooled RR: 0.82; 95% CI: 0.72, 0.93) for the highest compared with the lowest tertile of lutein blood concentration or intake.
- There was no significant association with type 2 diabetes mellitus (pooled RR: 0.97; 95% CI: 0.77, 1.22), but higher lutein was associated with a lower risk of metabolic syndrome (pooled RR: 0.75; 95% CI: 0.60, 0.92) for the highest compared with the lowest tertile.
- Our findings suggest that higher dietary intake and higher blood concentrations of lutein are generally associated with better cardiometabolic health.
- However, evidence mainly comes from observational studies in adults, whereas large-scale intervention studies and studies of lutein during pregnancy and childhood are scarce.
Choo YM et al. • The Cochrane database of systematic reviews (2025)
“While supplementation with lutein and zeaxanthin from day one of life in preterm infants until discharge probably reduces the incidence of ROP stage 3 and above, it may have little or no effect on the incidence of ROP at any stage, IVH or NEC, or mortality assessed throughout the NICU stay.”
Key Findings:
- Lutein and zeaxanthin supplementation probably reduces the incidence of ROP stage 3 and above (RR 0.49, 95% CI 0.29 to 0.81; P = 0.005; I2 = 0%; 4 studies, 532 infants; moderate-certainty evidence).
- While supplementation with lutein and zeaxanthin from day one of life in preterm infants until discharge probably reduces the incidence of ROP stage 3 and above, it may have little or no effect on the incidence of ROP at any stage, IVH or NEC, or mortality assessed throughout the NICU stay.
- However, the pooled estimates for these outcomes may change with further rigorously conducted trials.
- There were no adverse effects reported.
Evans JR et al. • The Cochrane database of systematic reviews (2023)
“Moderate-certainty evidence suggests that antioxidant vitamin and mineral supplementation (AREDS: vitamin C, E, beta-carotene, and zinc) probably slows down progression to late AMD.”
Key Findings:
- These studies enroled 11,952 people aged 65 to 75 years and included slightly more women (on average 56% women).
- People taking antioxidant vitamins were less likely to progress to late AMD (odds ratio (OR) 0.72, 95% confidence interval (CI) 0.58 to 0.90; 3 studies, 2445 participants; moderate-certainty evidence).
- Low-certainty evidence from one study of 110 people suggested higher quality of life scores (measured with the Visual Function Questionnaire) in treated compared with non-treated people after 24 months (mean difference (MD) 12.30, 95% CI 4.24 to 20.36).
- A similar risk of progression to visual loss of 15 or more letters was seen in the lutein/zeaxanthin and control groups (RR 0.98, 95% CI 0.91 to 1.05; 6656 eyes; low-certainty evidence).
Chew EY et al. • JAMA ophthalmology (2022)
“Results of this long-term epidemiologic follow-up study of the AREDS2 cohort suggest that lutein/zeaxanthin was an appropriate replacement for beta carotene in AREDS2 supplements.”
Key Findings:
- This study included 3882 participants (mean [SD] baseline age, 72.0 [7.7] years; 2240 women [57.7%]) and 6351 eyes.
- At 10 years, the odds ratio (OR) of having lung cancer was 1.82 (95% CI, 1.06-3.12; P = .02) for those randomly assigned to beta carotene and 1.15 (95% CI, 0.79-1.66; P = .46) for lutein/zeaxanthin.
- The hazard ratio (HR) for progression to late AMD comparing lutein/zeaxanthin with no lutein/zeaxanthin was 0.91 (95% CI, 0.84-0.99; P = .02) and comparing ω-3 fatty acids with no ω-3 fatty acids was 1.01 (95% CI, 0.93-1.09; P = .91).
- When the lutein/zeaxanthin main effects analysis was restricted to those randomly assigned to beta carotene, the HR was 0.80 (95% CI, 0.68-0.92; P = .002).
Hajizadeh-Sharafabad F et al. • Critical reviews in food science and nutrition (2022)
“The overall results supported possible protective effects of carotenoids on inflammatory biomarkers.”
Key Findings:
- The random-effect model was used to analyze data and the overall effect size was computed as weighted mean difference (WMD) and corresponding 95% of confidence interval (CI).
- A total of 26 trials with 35 effect sizes were included in this meta-analysis.
- Also, only lycopene (WMD: ‒1.08 pg/ml, 95%CI: ‒2.03, ‒0.12, P = 0.027) led to a significant decrease in IL-6.
