Marigold extract is taken from the flowers of marigolds and is known for their vivid yellow or orange color. Rich in carotenoids, flavonoids, and triterpenoids, marigold extract has antioxidant and anti-inflammatory properties that improve skin health by protecting against oxidative damage, soothing irritation, and supporting wound healing. Marigold extract is also believed to benefit eye health, as the carotenoids, lutein, and zeaxanthin present in marigold extract have been shown to protect the eyes from age-related macular degeneration.
Marigold Extract | Visual health and light protection system
Extraction technology
Supercritical CO₂ directed enrichment:
Esterification stabilization process: Lutein content ≥ 20%
Isomer control: All-trans lutein accounts for ≥ 95% (HPLC-PDA verification)
Lutein | Core mechanism of action
Optical properties and biological activity:
Blue light filtration: Absorption of 400-460nm high-energy blue light (shielding rate 82%)
Antioxidant network:
Quenching singlet oxygen (rate constant 2×10⁹ M⁻¹s⁻¹)
Regeneration of vitamin E (recycling rate ↑300%)
Eye-specific distribution:
Enrichment in the macula: Retinal concentration is 10,000 times that of blood
Blood-retinal barrier penetration: SR-B1 receptor-mediated transport
Clinical evidence of efficacyies
Vision protection
Macular pigment density: 35% increase in 6 months (MPOD measurement)
Contrast sensitivity: 28% improvement (Mesotest II test)
Anti-blue light damage
Digital visual fatigue: 43% reduction in CVS-Q score (people with daily screen use >8 hours)
Photoreceptor protection: Reduce blue light-induced ROS generation (in vitro model ↓69%)
Cognitive assistance
Memory function: Rey auditory test improved by 22% (elderly population)
Brain lutein content: MRI spectral detection increased by 3 times
Skin photoprotection
UV damage: 58% reduction in sunburn count (12 weeks of intervention)
Skin elasticity: 19% increase in Cutometer measurement

Special populations
Formula for premature infants: Low-dose microencapsulation (preventing ROP)
Special for pilots: Rapid release dosage form (for high-intensity light environments)
Usage specifications and contraindications
Recommended dosage
Daily maintenance: 10mg/day (taken after meals)
High-intensity eye use: 20mg/day (divided into 2 times)
Topical protection: 0.1-0.5% addition (once a day)
⛔ Notes
Smokers: need to be combined with vitamin C (reduce oxidative stress)
Bile duct obstruction: Absorption may be limited (water-soluble type is recommended)
β-carotene combined use: 4 hours interval is required (competitive absorption)
FAQ
Q: What is the difference between lutein ester and free lutein?
A: The stability of the esterified form is increased by 10 times (extended shelf life), and the intestinal absorption rate is increased by 38%. Our patented enzymatic hydrolysis technology ensures accurate conversion in the duodenum.
Q: How long does it take to take effect?
A: Macular pigment density test shows: accumulation starts at 4 weeks and reaches steady state at 16 weeks (continuous supplementation is recommended).
Q: Can it replace blue light blocking glasses?
A: Clinical data show that 20 mg/day oral administration + 0.1% topical application can provide a blue light filtering effect equivalent to that of AG400 lenses, but comprehensive protection is recommended.
