What is zeaxanthin good for?
Zeaxanthin belongs to a special group of compounds that are called carotenoids, which not only serve to give certain plants, fruits and vegetables their distinct red-orange-yellow hue, but also act as antioxidants.
Paprika, maize corn, saffron and goji berries all attribute their vivid colors to zeaxanthin, although there are many other examples, and the compound is also directly responsible for the taste and aroma of saffron itself. The name for Zeaxanthin is actually derived from a combination of "Zea mays", the most common species of maize corn, and "xanthos", which is the Greek word for yellow.
Zeaxanthin's role in eye health
There is a growing body of research that points to zeaxanthin and other carotenoids playing an important role in our eye health, not only regarding healthy vision but also in terms of reducing and treating diseases of the eyes. It is thought this is due to their high antioxidant and anti-inflammatory content, as many eye conditions are directly attributed to inflammation and oxidative stress.
Some of the most common eye conditions include age-related macular degeneration, or AMD, cataracts and glaucoma.
Interestingly, it has been found that being exposed to blue light waves could increase the production of free radicals and oxidative stress in the eyes, increasing the risk of developing these conditions. Research shows that zeaxanthin could potentially absorb this blue light, as well as increase macular pigment density, thus reducing inflammation and slowing the progression of disease, or preventing it outright.
Zeaxanthin's role in skin health
Much like other carotenoids like beta-carotene and lycopene, it is thought that zeaxanthin can offer protection from ultraviolet radiation on the skin, in a similar manner to how it protects the eyes from blue light.
When should I take zeaxanthin?
Zeaxanthin is a fat-soluble compound, which means that it shoudl be taken with a meal, ideally one that contains dietary fat, in order for the body to absorb it properly and get the most out of it.
