Zeaxanthin is a carotenoid, a type of pigment found in plants, particularly in colorful fruits and vegetables like corn, paprika, and oranges. It is closely related to lutein, another carotenoid, and together they are essential for maintaining eye health. Zeaxanthin is primarily concentrated in the retina, specifically in the macula, where it plays a critical role in protecting the eyes from damage caused by light and oxidative stress.

   Supplemental Benefits of Zeaxanthin:

Eye Health Maintenance

Zeaxanthin supplements are often recommended for individuals at risk of eye conditions such as AMD and cataracts. Studies have shown that regular supplementation with zeaxanthin can improve visual function and help protect the eyes from age-related damage. It works synergistically with lutein to enhance overall eye health.

Cognitive Support

Zeaxanthin, along with lutein, may support cognitive function. Supplementation has been linked to improved memory, processing speed, and overall brain health, particularly in older adults. This is due to its presence in the brain and its ability to protect against oxidative damage.

Skin Protection

Zeaxanthin’s antioxidant properties can benefit skin health. It helps protect the skin from damage caused by UV light and environmental pollutants, potentially improving skin hydration and elasticity.

Cardiovascular Health

Zeaxanthin may contribute to cardiovascular health by reducing oxidative stress and inflammation. Regular intake of zeaxanthin through diet or supplements may support overall cardiovascular function and help lower the risk of heart disease.

   Forms and dosage:

Zeaxanthin Esters:  Similar to lutein esters, zeaxanthin esters are zeaxanthin molecules attached to fatty acids. These need to be hydrolyzed in the digestive system to release free zeaxanthin. Zeaxanthin esters are commonly derived from marigold flowers.

Free Zeaxanthin:  Is not bound to fatty acids, making it more readily absorbed by the body. This form is also extracted from marigold flowers but is processed to remove the fatty acid components, facilitating better absorption.

Generally, if a zeaxanthin supplement does not specifically state that it is in free form, it is likely in the form of zeaxanthin esters. This is because esterified forms are more stable and easier to incorporate into various supplement formulations.

   Daily dose: 2 – 10 mg.
