Retinal and macular support. This antioxidant can be helpful in macular degeneration and boosting immune function.
Zeaxanthin is the yellow pigment found in paprika, corn, saffron, and marigolds. It is one of the two most important carotenoids in the retina - while lutein is found mostly in the edge of the retina, zeaxanthin is predominant in the central macula. Thus it is extremely important in fighting macular conditions such as macular degeneration and maintaining healthy vision.
Retinal pigment. One of zeaxanthin's benefits to macular degeneration is because it is a retinal pigment and as such acts as a filter for damaging radiation. The zeaxanthin that comes from red and orange foods in the diet (e.g. peppers, saffron) makes a greater contribution to macular pigment density than that which comes from green leafy vegetables.4
Glare recovery. One of the diagnostic tests for macular problems (to differentiate from optic nerve problems) is the glare recovery test in which the subject is exposed to bright light, such as the eye doctor's ophthalmoscope, and then measured how long it takes for visual acuity to return. Zeaxanthin, lutein, and meso-zeaxanthin make up most of the macular pigment which is essential to good glare recovery.5
Biomarker role. In 2016 researchers identified zeaxanthin an excellent biomarker (biomarkers are biochemicals in the body useful in diagnosis) in observing women's dietary intake. Zeaxanthin blood levels indicate the degree to which it is actually being absorbed by the body and being used by cell tissue.1
Cancer. Zeaxanthin is also one of the carotenoids identified as having a possible benefit role in preventing cancers such as non-Hodgkin lymphoma.2
Stem cell support. Researchers demonstrated that pre-treatment with zeaxanthin was helpful in supporting transplanted stem cells.3
Dr. Grossman has formulated the Advanced Vision Care Formula which contains zeaxanthin:
- The formulation has therapeutic levels of zeaxanthin made from pure marigold rather than
synthetic sources. Zeaxanthin is considered by experts to be the most important
carotenoid antioxidant for eye protection.*
Its the most needed by the eye but the least available in the diet (which provides only about 180 mcg/day. Our master formula contains 2 mg per Vcap for eye protection, and protection during injury or illness.
* Caution: Many eye products don't even contain zeaxanthin at all or skimp on it it is very expensive, including adding a token amount often listed in micrograms (mcg) such as 800mcg or less, and often it is synthetic.
- We use South American Zeaxanthin made from pesticide-free South American marigold
- Studies recommend 4 mg/day total (both zeaxanthin and lutein) to prevent AMD (Age-related Macular Degeneration) and cataracts
- Combined with lutein, helps effectively reduce free radicals
Daily need. 2-12mg per day.
