Mindsip insights from this episode:
Supplement to potentially reverse eye aging
Because eye health is expected to decline over time, the fact that supplementation improved function over a year suggests it may not just be halting decline but making the eyes functionally younger.
Supplement young eyes for enhanced function and recovery
Even in young individuals (average age 21) with normal eye health, 12 months of supplementation improved multiple measures of eye function, including glare resistance and photostress recovery.
Combine lutein and zeaxanthin for optimal retinal protection
Zeaxanthin concentrates in the central retina while lutein is more dispersed, suggesting they have complementary roles and that both are needed for optimal protection of the entire retina.
Transport lutein and zeaxanthin to high-damage areas for protection
Lutein and zeaxanthin can be actively transported to areas of the cell membrane experiencing high levels of UV radiation, concentrating their protective effects where they are needed most.
Supplement lutein and zeaxanthin for improved eye function
A 12-month study showed that lutein and zeaxanthin supplementation doesn't just improve proxy markers, but leads to statistically significant improvements in actual eye function like contrast sensitivity.
Consume over 5 milligrams of lutein and zeaxanthin daily for eye health
To see a benefit in macular pigment, a proxy for eye health, you need to consume more than 5 milligrams of lutein and zeaxanthin per day.
