This means some supplement products may not contain what the label says.
The macula is the most sensitive part of the retina and the one with the most photoreceptors.
These are special cells that convert light into signals that can be interpreted by your brain.
As such, the macula is the place where your sharpest vision is produced.
It is also responsible for your ability to perceive colors.
Zeaxanthin and another carotenoid calledluteinare the only dietary carotenoids that accumulate in the retina.
Because both zeaxanthin and lutein are found in large amounts in the macula, theyre known as macular pigments.
Further research is needed to prove the harmful effects of blue light.
No supplement is intended to treat, cure, or prevent disease.
It also helped reduce the risk of developing early-stage AMD by about 4%.
Cataracts
Zeaxanthin and lutein consumption may slow the formation of cataracts, which cause blurry vision.
Uveitis
Uveitisis an inflammation or swelling of the eye’s uvea.
The uvea is located in the center of the eye and is responsible for supplying blood to the retina.
Lutein and zeaxanthin may aid in slowing this inflammatory process.
Lutein and zeaxanthin may reduce the oxidation processes that damage the eyes in this way.
It concluded that lutein and zeaxanthin had a protective effect against retinal changes associated with diabetes.
The study authors suggested this combination dietary supplement should be considered in the overall management of AD.
However, it is unknown what effect zeaxanthin would have by itself.
What Are the Side Effects of Zeaxanthin?
Researchers have found no side effects from or negative interactions with zeaxanthin.
Therefore, you’d be smart to get zeaxanthin from food sources only.
Children
Zeaxanthin is possibly safe for use in children.
The study authors also noted the supplement was safe and well-tolerated.
However, more research is needed to confirm these findings and determine appropriate dosage.
Talk with your child’s healthcare provider before giving your child any supplements.
Dosage: How Much Zeaxanthin Should I Take?
There is currently no recommended dietary intake for zeaxanthin.
What Happens if I Take Too Much Zeaxanthin?
As a fat-soluble antioxidant, zeaxanthin requires some fat to be properly absorbed.
Or, if taking a supplement, do so with food.
But you shouldn’t limit yourself to just a few veggies.
Eggs may be your best source.
USP, a nonprofit, has set standards for supplements that Consumer Reports says are the most widely accepted.
