If you have been doing some research into the supplements that have the ability to protect your eyes and your vision for the long run, you might have come across selenium. But what exactly is selenium, and is it really necessary for eye health? Get the answers to your questions below.
What Is Selenium?
Selenium is a mineral that can serve as an antioxidant that protects your body against free radical damage that could lead to a host of diseases. Protecting the eyes against free radical damage is an important part of ensuring their long-term health.
Although selenium can be derived from foods like Brazil nuts, sunflower seeds, and mushrooms, as a few examples, taking a supplement that contains this nutrient can ensure that your body is able to easily absorb it and use it to protect the health of your eyes.
How Can Selenium Help Protect the Eyes?
Because selenium provides antioxidant protection to your entire body, it can also protect the eyes. More specifically, it could help to ensure the health of the lens of the eye.
Beyond that, however, experts have found that this mineral could also help to prevent glaucoma, which is a condition that is caused by excessive amounts of pressure within the eyes. It can do this by working with zinc to maintain the appropriate intraocular pressure.
Two studies involving rats found that selenium supplementation could have an impact upon eye health, including the health of the retina. The rats that were deficient in selenium had much more light damage on the retina than the rats that had been given enough selenium.
Research has also found that, if there is not enough selenium in your body, zinc is unable to work as effectively at maintaining healthy eyes, so taking selenium along with zinc can be even more beneficial.
The Benefits of a Comprehensive Eye Health Supplement
Because the nutrients that support the eyes, such as vitamin C, vitamin A, zinc, and selenium, work best when they are taken together, experts recommend taking an eye health formula that contains all of these valuable nutrients. In this way, you can ensure that these supplements will support one another in ways that will effectively protect the eyes and vision.
Although it is considered a trace mineral, selenium could be a great addition to your supplement routine, especially if you are hoping to protect the heath of your eyes and if you are hoping to maintain your visual acuity as you get older.
