What is Zeaxanthin?
Almost identical to Lutein, Zeaxanthin (zee-ah-ZAN-thin) is also a yellow compound or carotenoid, produced by plants to absorb light and can only be consumed by animals eating plants. It is the chemical responsible for the vivid yellow colour of saffron and yellow peppers.
Zeaxanthin gathers in high concentrations within the retina and is a significant part of the macular pigment, which is thought to protect the delicate light sensitive cells in macula against oxidative stress and visible blue light.
Like Lutein, Zeaxanthin is a powerful antioxidant and helps to absorb and neutralise the harmful effects of free radicals within the eye, which can potentially damage or even destroy cells within the retina.
Zeaxanthin helps to protect the eye by filtering out the visible blue light, found all around us in sunlight, car headlights, television screens and computer devices, that can over time be extremely damaging to the eye.
Where can I find them organically?
Fruits and vegetables are the most important dietary source of Zeaxanthin and is usually found in high concentrations along with Lutein.
Most studies measure Lutein and Zeaxanthin levels contained in foods together however some fruits and vegetables particularly those with a yellow/orange colour have been found to be particularly rich in Zeaxanthin these include … sweet corn, tangerines, oranges, kale, spinach, lettuce, peas, broccoli, peaches, celery, tomatoes, carrots and grapefruit.
The yolks of eggs also contain significant concentrations of Zeaxanthin along with Lutein.
How does Macu-STRENGTHTM help?
A single Macu-STRENGTHTM capsule contains 2mg Zeaxanthin, which is now regarded to be the optimum level required to enhance the macular function.
