24 Aug 2022 / Mohit Bhatia

There are certain plants and veggies such as carrots which have a vibrant color due to carotenoid pigment which provides veggies with their bright yellow, orange and red hues. Carotenoids are plant cells and are also known as phytonutrients. They’re antioxidant in nature and nutrients such as lutein, zeaxanthin and astaxanthin are a part of the carotenoid family!

Their antioxidant properties provide you with many health benefits as well as playing an essential role in plant health.

Lutein and zeaxanthin have been linked with improving and maintaining eye health as they’re the only dietary carotenoids found in your eye’s retina part. The unique molecular structure of astaxanthin allows it to cross the blood-brain barrier and enter your eyes! These carotenoids are known as macular pigments due to their prevalence in the macular region located in the back side of your eye; the part which is important for your vision! Out of all the tissues in human body, the retina contain maximum concentration of DHA

Lutein and zeaxanthin are found in high concentrations in green leafy veggies like spinach, lettuce, peas, broccoli, kale and others. You can also find this nutrients in egg yolks, pistachios, corn, red pepper and some varieties of wheat

Astaxanthin can be naturally found in algae and yeast. Fishes which feed on these marine plants tend to be higher in astaxanthin and have a reddish coloration like salmon, lobster, krill, shrimp, crab and more. 

Each of these super nutrients is fat soluble. This means that for their best absorption in your body, they should be had with a source of dietary fat. So do add a drizzle of olive oil to your salad or butter to your veg sandwich for ideal absorption!

AMD sufferers when supplemented with our super nutrients lutein and zeaxanthin have shown to reduce the rate of advancement of this ailment! It may also have preventative properties to reduce the occurrence or slow the onset of degeneration! (1).

Lutein and Zeaxanthin improve our eye health without any side effects. In 1 study, participants who were smokers when supplemented with beta carotene were showing increased risk of lung cancer due to beta carotene’s nature. Researchers noticed that when switched to lutein and zeaxanthin, the participants showed no increased risk of lung cancer due to lutein and zeaxanthin and showed improvements in their eye health (2,3).

The rate of formation was slower for eye diseases like cataract in individuals who were having a high intake of lutein, zeaxanthin and astaxanthin (4).

It is known that lower levels of DHA, lutein, zeaxanthin,astaxanthin and DHA are associated with dry eye syndrome and diabetic retinopathy. (5, 6, 7). Dry eye syndrome is where your eyes don't produce enough lubrication (8). Diabetic retinopathy is a disease in diabetic patients which causes progressive damage to your retina. It impacts 4 out of 10 diabetic patients. Having these nutrients in your system therefore will help prevent or reduce these symptoms.(9, 10, 11).

The anti-inflammatory properties of zeaxanthin and lutein aid in slowing down uveitis; an inflammation occurring in the eye’s central area also known as uvea. (12)

Research has also been done to understand how lutein can improve vision problems associated with long-term blue light exposure from our screens. Participants who took lutein supplementation showed improvement in vision functions compared to placebo (13).

Researchers in a study concluded that lutein should be a primary focus on a lutein rich diet as well as encouraging supplementation especially in older adults and for those who are having recurring issues with their eye health (14).

Similar results have been found for DHA as well (21, 22, 23, 24).

4. Cancer 

While more human studies are required to provide definitive conclusions, a high intake of lutein, zeaxanthin, astaxanthin and other carotenoids have shown to be associated with improved prognosis and reduced risk of certain cancers such as pancreatic cancer, head & neck cancer and breast cancer (25, 26, 27, 28, 29, 30).

5. Brain Health

Carotenoids were found to play a major role in reducing risk of neurodegenerative disorders however more research is required in this area. (31, 32). Higher dietary and supplementary intake of lutein, zeaxanthin and astaxanthin are linked with promoting brain and cognitive functions such as improved and enhanced memory  (33, 34, 35).

6. Protects against UV damage
