Lutein + Zeaxanthin

Lutein and zeaxanthin are carotenoids, naturally occurring pigments found in plants that play a critical role in human health, especially in eye health. These compounds are chemically similar, with strong antioxidant properties, and are found in high concentrations in the macula of the human eye. The macula is a part of the retina responsible for central vision and high-resolution color vision. Consuming lutein and zeaxanthin can have several health benefits, most notably in preventing or ameliorating age-related macular degeneration (AMD) and cataracts. Here are some of their health benefits:

1. Eye health:
   • Lutein and zeaxanthin act as blue light filters, absorbing harmful high-energy blue wavelengths that can damage the macula over time.
   • They neutralize reactive oxygen species and free radicals that can cause oxidative stress in the retina, a key factor in AMD development.
   • Higher macular pigment density (from lutein and zeaxanthin) is associated with a reduced risk of AMD progression and cataracts formation.
2. Macular pigment density:
   • The macular pigment is composed of approximately 85% lutein and 15% zeaxanthin.
   • Higher macular pigment density improves visual acuity, contrast sensitivity, and glare recovery, enhancing overall visual performance.
   • Supplementation with lutein and zeaxanthin has been shown to increase macular pigment density, especially in those with low baseline levels.
3. Synergistic effects:
   • While structurally similar, lutein and zeaxanthin have slightly different molecular properties and functions. Lutein is more effective at quenching triplet state molecules and zeaxanthin is better at scavenging superoxide radicals. Together, they provide a broader spectrum of antioxidant protection and may enhance each other's bioavailability and absorption.
4. Cognitive function:
   • Lutein and zeaxanthin can cross the blood-brain barrier and accumulate in brain tissues, particularly in the prefrontal cortex and hippocampus.
   • Higher levels have been associated with better cognitive performance, memory, and reduced risk of cognitive decline and dementia.
   • Their anti-inflammatory and neuroprotective properties may contribute to cognitive benefits.
5. Skin health:
   • Lutein and zeaxanthin can accumulate in the skin and act as natural sunscreens, absorbing UV radiation and protecting against photoaging and skin damage.
   • Their antioxidant properties may help neutralize free radicals generated by UV exposure, which can lead to wrinkles and age spots.
   • They also have anti-inflammatory effects in the skin, potentially benefiting conditions like psoriasis or eczema.
