Benefits
AREDS2 Foundation Ingredient — AMD Risk Reduction
FloraGLO Lutein was the lutein source used in the landmark AREDS2 (Age-Related Eye Disease Study 2) trial. AREDS2 established lutein + zeaxanthin (with zinc and antioxidant vitamins) as evidence-based intervention for reducing progression of intermediate to advanced AMD.
Macular Pigment Density Increase
Multiple clinical trials demonstrate FloraGLO at 10 mg/day increases macular pigment optical density (MPOD) significantly. MPOD is protective against AMD and supports visual function. Effects sustained with continued supplementation.
Blue Light Protection
Lutein absorbs harmful blue light that penetrates retinal tissue from sun, screens, LEDs. FloraGLO Lutein provides systemic blue light filtering at retinal level. Kemin holds blue light patent for presbyopia, hyperopia, astigmatism.
Cognitive Function Support
Multiple studies demonstrate FloraGLO Lutein supports cognitive flexibility, complex attention, and brain network connectivity in adults. Crosses blood-brain barrier; concentrates in brain tissue.
Maternal and Infant Nutrition
First NIH-funded clinical study on pregnant mothers and babies showed FloraGLO Lutein + OPTISHARP Natural Zeaxanthin supplementation significantly improved carotenoid levels. Lutein naturally present in breast milk; supports infant eye and brain development.
Skin Health (Beauty-from-Within)
10 mg FloraGLO supplementation in healthy women showed benefits in skin parameters — protects from blue light skin damage, antioxidant skin support.
Adolescent Macular Pigment Density
ARVO 2025 research suggests FloraGLO Lutein supplementation can boost macular pigment levels in healthy adolescents — relevant given adolescent screen time.
Mechanism of action
Macular Pigment Concentration
Lutein is one of two major xanthophyll carotenoids (with zeaxanthin) concentrated in macular region of retina. Forms macular pigment that filters blue light and quenches reactive oxygen species. Foundation of retinal antioxidant defense.
Blue Light Filtering
Lutein efficiently absorbs higher-energy (blue and ultraviolet) light, preventing photoreceptor damage. Critical given modern blue light exposure from digital devices.
Antioxidant Activity in Retina/Brain/Skin
Lutein scavenges singlet oxygen and other reactive oxygen species; protects cellular membranes and DNA from oxidative damage in retina, brain, and skin.
Free (Unesterified) Form Bioavailability
FloraGLO uses FREE LUTEIN form (not lutein esters) — directly absorbed without enzymatic hydrolysis. Optimal bioavailability vs ester forms.
Brain Tissue Distribution
Lutein crosses blood-brain barrier and concentrates in brain tissue, supporting cognitive functions and possibly neuroprotection.
Clinical trials
Landmark large-scale RCT of lutein + zeaxanthin (with zinc and antioxidants) for AMD progression. FloraGLO Lutein was the lutein source used.
AREDS2: 4,203 participants ages 50-85 with intermediate AMD risk.
Reduced progression to advanced AMD vs no lutein/zeaxanthin. Foundation of evidence-based AMD nutritional intervention.
Multiple RCTs of FloraGLO Lutein for cognitive function in adults including older adults.
Adults across cognitive function studies.
Improvements in cognitive flexibility, complex attention, brain network connectivity, and processing speed. Established lutein cognitive applications.
First NIH-funded clinical study on pregnant mothers and babies supplemented with FloraGLO Lutein and OPTISHARP Natural Zeaxanthin.
Pregnant mothers and their infants.
Significant improvement in maternal and infant carotenoid levels. Foundation for maternal/infant nutrition applications.
About this ingredient
FLORAGLO® LUTEIN is the WORLD'S MOST RESEARCHED LUTEIN BRAND — manufactured by KEMIN INDUSTRIES from MARIGOLD FLOWERS (TAGETES ERECTA) using meticulous extraction processes. LUTEIN is one of two major XANTHOPHYLL CAROTENOIDS (with zeaxanthin) concentrated in MACULAR REGION of retina — forms protective macular pigment. FloraGLO uses FREE (UNESTERIFIED) LUTEIN form for optimal bioavailability vs. ester forms (which require enzymatic hydrolysis before absorption).
KEY DISTINCTIONS: (1) FIRST LUTEIN BRAND introduced globally — set the standard; (2) Over 100 HUMAN CLINICAL TRIALS — most-researched lutein ingredient; (3) AREDS2 LANDMARK STUDY foundation ingredient; (4) GRAS STATUS for maternal and infant use; (5) Plant-based, non-GMO, vegetarian, gluten-free; (6) DSM Actilease® microencapsulation technology for stability; (7) BLUE LIGHT PATENT for presbyopia, hyperopia, astigmatism conditions; (8) Multiple application platforms — eye, brain, skin, maternal/infant.
EVIDENCE-BASED USES: (1) AMD PROGRESSION REDUCTION (AREDS2 foundation); (2) MACULAR PIGMENT density increase (multiple trials); (3) Blue light protection (eye + skin); (4) COGNITIVE FUNCTION support (cognitive flexibility, attention, brain network connectivity); (5) MATERNAL/INFANT NUTRITION (NIH-funded study); (6) SKIN HEALTH beauty-from-within; (7) Adolescent macular pigment (ARVO 2025); (8) Visual function and contrast sensitivity.
CRITICAL CAUTIONS: (1) DOSE — 10 mg/day FloraGLO Lutein research-validated; typically combined with 2 mg OPTISHARP™ Natural Zeaxanthin (Kemin's natural zeaxanthin from same marigold source); (2) DURATION — macular pigment density changes build over 3-6 months; cognitive effects build over similar timeframe; (3) AREDS2 INDICATION — AREDS2 supplements specifically formulated for INTERMEDIATE AMD; for prevention in low-risk individuals, evidence is less specific but lutein supplementation generally safe; (4) ADVANCED AMD — requires ophthalmological treatment (anti-VEGF injections); supplements adjunctive; (5) PREGNANCY/LACTATION — GRAS status; safe; FloraGLO specifically studied in maternal nutrition; (6) CHILDREN — safe; FloraGLO is the most-researched lutein for infant formula fortification; (7) BLUE LIGHT EXPOSURE — modern lifestyle (screens, LEDs) increases blue light exposure; supplementation provides antioxidant defense; (8) FLORAGLO vs OTHER LUTEIN BRANDS — most-researched; free form bioavailability advantage; specific evidence base across applications; (9) FLORAGLO vs LUTEIN ESTERS — free form requires no enzymatic hydrolysis; better bioavailability; (10) FOR COMPREHENSIVE EYE HEALTH — sun protection, lutein/zeaxanthin (FloraGLO + OPTISHARP), zinc, antioxidant vitamins, omega-3s, regular ophthalmologist exams; (11) FOR COGNITIVE HEALTH — emerging evidence supplements traditional cognitive support approaches; (12) BIOAVAILABILITY ENHANCEMENT — fat consumption with lutein meal improves absorption (carotenoids are fat-soluble); (13) MARIGOLD SOURCE — sustainable Tagetes erecta cultivation; 25+ years of refined production; (14) BRAND VERIFICATION — FloraGLO® is Kemin trademark; specific clinical evidence is for this branded form; generic lutein products may differ in form (esters vs free), bioavailability, and clinical evidence.
