Zeaxanthin is available over the counter in most parts of the world. Being one of only two carotenoids chosen by mother nature to prevent damage to eye tissue and thus ward off visionary defects, this antioxidant is highly sought after. Many discount stores and grocery stores out there often sell their own generic version of the substance.
However, there is something that you need to know before you walk off to buy zeaxanthin from the friendly neighborhood store.
The first thing is that zeaxanthin does not work alone–it also works with a counterpart called lutein. Both are carotenoids that exist in our eyes. Lutein and zeaxanthin act as a team that exists within the tissues of the macula – the central part of the retina.
While zeaxanthin takes care of repair and prevention of damage to the cones around the periphery of the retina, lutein does the same to the rods in the center of the retina.
Harmful ultraviolet rays enter the eye and create ionized atoms that are very damaging to living tissue. These ionized atoms are called ‘free radicals’. Free radicals are constantly trying to stabilize by attracting an electron from a nearby atom. When it manages to capture an electron from another atom the atom that loses an electron becomes unstable and thus becomes a free radical.
This process continues until there is a supply of free electrons to stop the creation of free radicals the more the number of free radicals the more the damage. Fortunately nature has resolved this problem by creating antioxidants that are substances rich in free electrons.
Lutein and zeaxanthin are the antioxidants that are chosen to prevent damage to the eye tissue. Many consumers, learning of the benefits of this carotenoid, have flocked to the market to buy zeaxanthin. Many zeaxanthin and lutein supplements flooded the market as well.
But before you buy zeaxanthin, check if the supplement contains lutein as well. It should contain a minimum dosage of 10 to 20 mg of both zeaxanthin and lutein in order for the supplement to be effective.
Be careful of what supplements you purchase in discount stores. More often than not, these supplements, especially the generic ones, will lack adequate amounts of lutein and zeaxanthin. As said before, look for 10 to 20 mg of each. The higher the dosage of each carotenoid, the better the supplement.
Once you are sure that the produce meets the minimum requirement in terms of dosage and content you can go ahead and buy zeaxanthin and protect your eyes from damage and ensure long and healthy vision. For more information on the best types of supplements, click on over to the site below.
