ZeaONE® - A Natural Dietary Zeaxanthin Ingredient for Eye Health
Dietary zeaxanthin, like lutein, is naturally deposited in the eyes to form macular pigment, which keeps our eyes functioning their best. Zeaxanthin is found naturally in common vegetables like corn, squash and peppers. But, most americans only get 10% of the recommended amount.
ZeaONE Zeaxanthin is a supplement ingredient for eye health. It's naturally-sourced from the same marigold flowers as FloraGLO Lutein. These two nutrients work together to filter damaging blue light and enhance quality of vision. 22-25 When formulated into a supplement with FloraGLO Lutein, ZeaONE Zeaxanthin:
- Helps eyes recover more quickly from intense light10,11
- Enhances quality of vision, even in people with 20/20 vision22-25
- Filters excess blue light12,13
- Helps reduce the progression of advanced macular degeneration (AMD)
The importance of zeaxanthin supplementation
Current research recommends at least 10 mg of lutein and 2 mg of zeaxanthin daily to keep eyes healthy and performing their best. Since the human body doesn't produce these carotenoids, it's important to consume these nutrients from foods or dietary supplements. Most individuals aren't consuming enough fruits and vegetables that contain lutein and zeaxanthin. In fact, most people only get 1-2 mg each day - far below the amounts proven to be beneficial for eye health.15
Many formulations don't provide natural, free-form dietary zeaxanthin
ZeaONE is free-form zeaxanthin naturally-sourced from marigold flowers. It's important to realize that not all zeaxanthin ingredients are equal. And the difference between them is significant...
Our body prefers free-form zeaxanthin
Through diet and supplementation, zeaxanthin is absorbed and selectively deposited in the eye, brain, skin and even breast milk.13-12 Research has shown that only the free-form of zeaxanthin is found in these tissues and is directly absorbed into the bloodstream delivering all important intended benefits, while zeaxanthin esters or meso-zeaxanthin is not.13
While there is evidence that esters can be converted to free-form zeaxanthin by our bodies, the rate of conversion is not well-studied and the mechanism, for the most part, is unknown. In fact, before zeaxanthin esters can be bioavailable and absorbed, the body must first solubilize them in fat and then de-esterify them by enzymatic cleavage of the fatty acids through a complex process that varies greatly among individuals and affects absorption.13
Since esters may not be efficiently absorbed by our bodies in order to use them, free-form zeaxanthin - like the one found in the majority of the fruits and vegetables that we eat - is the preferred form.

Beware of Meso-Zeaxanthin: Demand the Real Thing
Not all zeaxanthin is the same. Some products are misrepresented as containing dietary zeaxanthin, when in fact, they are purposefully formulated to contain a zeaxanthin stereoisomer: 3R, 3’S-meso-zeaxanthin. Meso-zeaxanthin, sometimes confusingly referenced on labeling as “zeaxanthin isomers,” is quite different than dietary zeaxanthin and is not a suitable replacement.
Meso-zeaxanthin is not found naturally in the diet
Our eyes are naturally protected by macular pigment. The body absorbs lutein and zeaxanthin through our diet and selectively deposits them into macular pigment. Meso-zeaxanthin is also found in macular pigment since the body naturally converts lutein to meso-zeaxanthin via an ensymatic process that occurs within the structures of the eye.19-21
Nature has given us abundant sources of zeaxanthin like the dietary zeaxanthin found in ZeaONE zeaxanthin. Meso-zeaxanthin; however, is not found naturally in any conventional dietary source.
The Science behind Meso-zeaxanthin is not Developed
Evidence to support the use of meso-zeaxanthin is lacking compared to the overwhelming support in the published literature linking zeaxanthin and lutein supplementation to improved eye health.14
To date, there has been no published research on the eye health or otherwise, in animal models or human clinicals using supplemental meso-zeaxanthin alone without the presence of zeaxanthin and lutein. This makes it impossible to attribute any effects to meso-zeaxanthin alone.
Additionally, research shows that supplemental meso-zeaxanthin may compete with zeaxanthin and lutein absorption, hindering them from reaching the macula where they are critical for maintaining healthy eyes and protecting our vision as we age.15-17
Choose free-form zeaxanthin
Hundreds of studies have shown that zeaxanthin and lutein help keep our eyes healthy, improve visual performance and maintain eye health as we age. In fact, the benefits of zeaxanthin and lutein supplementation are supported by 30 years of clinical studies.5-23
