Lutein and Zeaxanthin: Updated Studies on Carotenoids for the Eyes

Lutein and zeaxanthin are two important nutrients found in various parts of the body, including the retina and eye lenses. Acting as powerful antioxidants, they are like an internal pair of sunglasses, filtering out harmful UVA/UVB and blue light. Additionally, they aid in reducing night glare, enhancing visual sharpness, and improving color contrast. Research indicates … Continue reading “Lutein and Zeaxanthin: Updated Studies on Carotenoids for the Eyes”

Lutein, Zeaxanthin, Meso-Zeaxanthin – An Update

Your Eyes Benefit from Lutein, Zeaxanthin, and Meso-zeaxanthin Lutein, zeaxanthin, and meso-zeaxanthin are potent antioxidants found in green leafy vegetables, eggs, corn and even chocolate. They have a profound effect on preserving healthy vision, brain function, the immune and cardiovascular systems. New research is focusing less on the well-established understanding of local benefit from nutrients, … Continue reading “Lutein, Zeaxanthin, Meso-Zeaxanthin – An Update”

Basic Duo: Lutein and Zeaxanthin

These powerhouses provide a great starting point for your vision nutrition. Lutein and zeaxanthin (along with mesozeaxanthin) are carotenoids, a class of mostly yellow, orange, or red fat-soluble pigments, including carotenes, which give color to plant parts such as ripe tomatoes. These macular pigments act as an internal pair of sunglasses to protect the retina from … Continue reading “Basic Duo: Lutein and Zeaxanthin”

Zeaxanthin and Lutein Save the Eyes and Improve Brain Circulation

The antioxidants lutein and zeaxanthin help keep the eyes healthy. A new study has found that these nutrients also improve the circulation of blood to the brain. Seniors experience gradual cognitive decline. A recent study showed that taking enough of these antioxidants halted cognitive decline. Research supports the idea that nutrition has a direct impact … Continue reading “Zeaxanthin and Lutein Save the Eyes and Improve Brain Circulation”

Lutein Absorption Higher as a Solid-Lipid Particle Complex

Lutein absorption can be improved by adding solid-lipid particles to the formula.  What does that mean?   Lipids are fats and solid-lipids are fats which are solid at room temperature.  Researchers have noted that lutein from egg yolks is more readily absorbed than the ester form of lutein. Researchers wanted to know whether combining ester lutein … Continue reading “Lutein Absorption Higher as a Solid-Lipid Particle Complex”

Low Intake of Antioxidants & Lutein Associated with Macular Degeneration (ARMD)

Eating plenty of fruits and vegetables helps ward off a common eye disease, age-related macular degeneration (ARMD). A study in Acta Ophthalmologica looked at the relationship between intake of antioxidants (including the antioxidant lutein) and the incidence of macular degeneration. It found that people with low intake of antioxidants were twice as likely to have … Continue reading “Low Intake of Antioxidants & Lutein Associated with Macular Degeneration (ARMD)”

AMD Inhibited by Lutein, Carotenoids, and Zeaxanthin Antioxidants

New evidence continues to support dietary lutein, carotenoids, zeaxanthin, and meso-zeaxanthin as a means of inhibiting development of age-related macular degeneration (AMD). AMD is the leading cause of loss of vision in Western people over age 55. A study published in 2010, in Archives of Biochemistry and Biophysics by the Department of Ophthalmology and Visual … Continue reading “AMD Inhibited by Lutein, Carotenoids, and Zeaxanthin Antioxidants”

Lutein – More Than Meets the Eye

The macular pigment of the eye is formed by a combination of lutein and zeaxanthin. Lutein is more than just a filter of blue light and an antioxidant. Consider these points about lutein: Animals who received no lutein  in their diets showed early degenerative signs in the retina. Macular pigment is important: patients with macular telangiectasia … Continue reading “Lutein – More Than Meets the Eye”

Lutein and Zeaxanthin Support Healthy Eyes and Fight Macular Degeneration

Macular xanthophylls | Lutein & Zeaxanthin | Zeaxanthin  Lutein Absorption | Role of Antioxidants Macular xanthophylls Macular xanthophylls, perhaps better known as lutein and zeaxanthin, are well known for their role as protectors against age related macular degeneration (AMD). Research at the University of Georgia is also finding that lutein and zeaxanthin supplementation can help … Continue reading “Lutein and Zeaxanthin Support Healthy Eyes and Fight Macular Degeneration”

Improve Eyes’ Light Sensitivity with Lutein and Zeaxanthin

Do you find that your eyes are sensitive to bright lights? A study published in the journal Optometry & Vision Science describes how the carotenoids lutein and zeaxanthin were found to positively effect many visual performance issues (including contrast sensitivity) when one is exposed to glaring light conditions.  Carotenoids are organic pigments that are naturally … Continue reading “Improve Eyes’ Light Sensitivity with Lutein and Zeaxanthin”
