AREDS 2 are vitamin supplements that may improve eye health for people with wet age-related macular degeneration (AMD). But AREDS 2 cannot prevent wet AMD.
Eye health matters. By 2050,
That’s why taking steps to slow the progression of this chronic eye disorder is important for people who have been diagnosed with intermediate AMD.
More and more data is emerging about a regimen of vitamin supplements known as AREDS 2 that has the potential to promote eye health and delay intermediate AMD progressing into late AMD.
AREDS 2 can help slow down vision loss, yet many questions remain on how it works and how to use the vitamin supplements. If you’ve been diagnosed with intermediate AMD, or you’re simply looking for natural ways to maintain good eye health, here’s everything you need to know about AREDS 2.
AREDS 2 is a regimen of vitamin supplements that includes a specific combination of vitamin C, vitamin E, copper (cupric oxide), zinc, lutein, and zeaxanthin.
| Ingredient | Amount in AREDS 2 |
|---|---|
| vitamin C | 500 milligrams (mg) |
| vitamin E | 400 IU (international units) |
| copper (cupric oxide) | 2 mg |
| zinc | 80 mg |
| lutein | 10 mg |
| zeaxanthin | 2 mg |
This specific combination was formulated thanks to clinical trials called the
AREDS 2 vitamin supplements can be purchased without a prescription in various drugstores or through online retailers.
The specific combination of vitamins in AREDS 2 is designed to benefit eye health for people with intermediate or late stage AMD. If one eye is more affected and has progressed to wet AMD, the vitamins in AREDS 2 may help slow progression in the other eye.
Vitamin C, for example, can lower the risk of developing cataracts and can slow the progression of wet AMD and vision loss.
Vitamin E, on the other hand, protects cells in the eyes from free radicals, which can break down healthy tissue.
Each ingredient in the AREDS 2 formulation has its own positive impact on eye health, so researchers combined the most effective ones into what’s essentially a “super vitamin” for the eyes.
It’s important to note that these vitamin supplements are not intended for general use. Researchers recommend consulting with an eye care professional to discuss whether they’re right for you.
Like all supplements, while AREDS 2 can
Some side effects can be attributed to the high levels of vitamins and minerals in the AREDS 2 formula, which can potentially change the way your body digests food. This can result in gastrointestinal issues like nausea, vomiting, or bloating.
An earlier type of wet AMD regimen known as AREDS was made with beta-carotene, which can increase the risk of lung cancer in people who smoke or used to smoke.
AREDS 2, however, is made without beta-carotene, so it’s important to choose the newer AREDS 2 supplements if you decide to use this vitamin regimen.
Taking AREDS 2 might change the way other medications work in your body, so it’s important to discuss your other medications and supplements with a doctor and pharmacist before starting AREDS 2.
For instance, the vitamin E in AREDS 2 has been
Currently, no nutritional supplements or combinations of them can prevent wet AMD. So, while AREDS 2 can be a useful tool in slowing the progression of the chronic eye disorder, it won’t be able to prevent wet AMD from developing.
You can also decrease your risk of wet AMD through a number of healthy lifestyle changes, like quitting smoking and eating a diet rich in fruits, vegetables, and fish high in omega-3s.
In addition to those vitamins included in the AREDS 2 mix, folate can be extremely helpful for maintaining good eye health and slowing the progression of wet AMD.
You can increase your folate intake through a supplement or by eating folate-rich foods like:
- oranges
- peanuts
- black-eyed peas
- spinach
- grains
Omega-3 fatty acids can also help maintain eye retina health. Researchers recommend eating fish 2 to 3 times a week for its health benefits, preferably:
- salmon
- sardine
- mackerel
- herring
- lake trout
- canned light tuna
If you don’t like or don’t eat fish, you can take an omega-3 supplement or find omega-3s in:
- flaxseeds
- walnuts
- canola oil
- some fortified foods
Vitamin A is another supplement that can boost your eye health. If you’ve ever heard the phrase “eating carrots is good for your eyes,” that’s because they actually are. Carrots are rich in vitamin A, which can slow wet AMD progression.
However, vitamin A is also known as beta-carotene and comes with the risks noted. So keep an “eye” on your intake and check with your doctor before taking it.
Nutritional supplements can’t prevent wet AMD, but they can slow the progression of dry AMD before wet AMD develops.
The AREDS 2 regimen has been proven to be particularly helpful in maintaining eye health. To learn more about AREDS 2 or to find out if it’s right for you, ask a doctor about the pros and cons, as well as other steps to promote good eye health.
