Lutein and Zeaxanthin
Lutein and zeaxanthin are both different isomers of the same xanthophyll pigment molecule. They are naturally occurring carotenoids found in highest abundance in green leafy vegetables. Both of these molecules play a large role in eye health. They are both found to be highly concentrated in the retina, which is the lining on the back of the eye that is responsible for vision.
Lutein and zeaxanthin are responsible for the ability of our eyes to absorb blue light, which is a wavelength of light that produces free radicals and puts significant oxidative stress on tissues. Studies show a correlation between high lutein consumption and increased pigmentation of the retina. Increased pigment has been shown to lower your risk of macular degeneration and cataracts, although it doesn’t reverse already established illnesses. Interestingly, lutein is found in highest concentration in the peripheral retina, which better senses motion and black-and-white.
Zeaxanthin, on the other hand, is found to be highly concentrated in the macula, the more detail and colour-sensitive region of the retina. Lutein may also prove helpful for retinopathies associated with advanced diabetes likely from protection against damage from excess sugar in the blood.
High lutein consumption has been associated with a reduced incidence of prostate cancer in men. It may also help prevent or slow down the thickening of the arteries known as atherosclerosis, which is a major risk for cardiovascular disease. Interestingly, cardiovascular disease is often accelerated by free radical damage.
How can I get lutein and zeaxanthin?
Eating a diet rich in green leafy vegetables like spinach, kale and collard greens is a great way to increase your lutein and zeaxanthin intake. As a supplement, lutein comes individually in capsules, or as a sublingual spray for those with compromised digestion. Both lutein and zeaxanthin can be found in a number of combination formulas for eye health. There is currently no recommended dosage for lutein or zeaxanthin. Many supplements commonly suggest between 6-12mg/day of lutein and 2-6mg/day of zeaxanthin. It is advisable to follow the recommended dosage provided by each manufacturer.
Lutein and zeaxanthin are non-toxic, but can cause harmless yellow-orange skin pigmentation if consumed in very large amounts. Lutein and Zeaxanthin are two carotenoids essential for maintaining eye health:
- Provides antioxidant for the maintenance of eye health.
- Helps to reduce the risk of developing cataracts.
- Helps to improve macular pigment optical density.
- Helps to maintain eyesight in conditions (associated with sunlight damage), such as cataracts and age-related macular degeneration.
