Welcome, health enthusiasts! Are you looking for a natural way to take care of your eye health? If yes, then the AREDS 2 ingredients are what you need to know. AREDS 2 stands for Age-Related Eye Disease Study 2, a research study conducted by the National Eye Institute. The study revealed that certain vitamins and minerals can significantly reduce the risk of age-related macular degeneration (AMD) and improve visual function. In this article, we will explore all you need to know about the AREDS 2 ingredients and how they benefit eye health.
What is AREDS 2?
AREDS 2 stands for Age-Related Eye Disease Study 2. It is a study conducted by the National Eye Institute in the United States to investigate the effectiveness of specific nutrient supplements in reducing the risk of developing advanced age-related macular degeneration (AMD). This study is a follow-up to the original AREDS study, which was conducted between 1992 and 2001.
The original study showed that a specific combination of high-dose antioxidants and minerals, including vitamins C and E, beta-carotene, zinc, and copper, reduced the risk of advanced AMD by 25% in people with intermediate AMD or advanced AMD in one eye. However, some concerns were raised about the use of beta-carotene, which was found to increase the risk of lung cancer in smokers. A number of other studies since then have also suggested that beta-carotene may not be safe for all populations. Therefore, AREDS 2 was conducted to look at alternative supplements to beta-carotene.
The AREDS 2 study, which was conducted between 2006 and 2012, tested whether a modified formula would be even better in reducing the risk of advanced AMD. The new formula included the same nutrients as the original formula but with some modifications. Lutein and zeaxanthin, which are carotenoids that are also found in the macula and retina, were added to the formula instead of beta-carotene. Omega-3 fatty acids, which have shown some benefit in reducing inflammation, were also added to the formula.
The AREDS 2 study involved over 4,000 participants aged 50 to 85 with intermediate or advanced AMD in one eye. The subjects were randomly assigned to one of four study arms. The first group received the original AREDS supplement formula with beta-carotene, while the second group received the same formula without beta-carotene. The third group received the modified formula with lutein and zeaxanthin instead of beta-carotene, and the fourth group received the modified formula with added omega-3 fatty acids.
The primary outcome of the study was to evaluate whether the modified formula was as effective, or even more effective, in reducing the risk of developing advanced AMD than the original formula. It was found that the modified formula was indeed effective in reducing the risk of advanced AMD, and it was just as effective as the original formula. Moreover, there was a lower risk of lung cancer in smokers or former smokers who took the modified formula without beta-carotene.
Therefore, the AREDS 2 study concluded that the modified formula, which contains vitamins C and E, zinc, copper, lutein, zeaxanthin, and omega-3 fatty acids, is a safe and effective supplement for reducing the risk of advanced AMD. Although it cannot cure AMD or restore vision that has already been lost, it can help to slow down the progression of the disease and preserve vision in people with intermediate or advanced AMD.
The Original AREDS Formula
The Age-Related Eye Disease Study (AREDS) is a large clinical trial sponsored by the National Eye Institute. This study aimed to investigate the effects of nutritional supplements on the progression of age-related macular degeneration (AMD) and cataracts, the leading causes of vision loss in older people. The original AREDS formula was formulated in 2001 based on the study’s findings and consisted of a combination of vitamins, minerals, and antioxidants that were believed to reduce the risk of developing advanced AMD.
The original formula included the following ingredients:
- Vitamin C – 500 mg
- Vitamin E – 400 IU
- Beta-carotene – 15 mg
- Zinc – 80 mg
- Copper – 2 mg
Vitamin C and vitamin E were included in the formula because they have antioxidant properties and can neutralize free radicals that damage cells in the eyes. Beta-carotene is a precursor to vitamin A and is essential for good eye health. Zinc is involved in various physiological processes in the body, including the production of melanin, which protects the eyes from harmful ultraviolet radiation. Copper helps to maintain the structure and function of the retina, the part of the eye that detects light.
The AREDS formula was a significant breakthrough in the field of eye health and was proven to be effective in reducing the risk of developing advanced AMD by up to 25%. However, the original formula had some limitations. For example, the formula was not suitable for smokers as it contained beta-carotene, which has been linked to an increased risk of lung cancer in smokers. Therefore, a new formula was needed that would remove beta-carotene and replace it with safer and more effective ingredients.
AREDS 2 Formula
The AREDS 2 formula was launched in 2013, following another large clinical trial that aimed to build on the original formula’s success and identify new ingredients that could further reduce the risk of AMD and cataracts.
The AREDS 2 formula included the following changes:
- Removing beta-carotene
- Adding lutein and zeaxanthin – 10 mg and 2 mg, respectively
- Reducing zinc – 25 mg
- Adding omega-3 fatty acids – 1000 mg
- Removing vitamin A – 1000 IU
- Adding vitamin D – 400 IU
Lutein and zeaxanthin are carotenoids that are naturally found in the macula, the part of the eye that is responsible for central vision. They act as antioxidants and help to filter out harmful blue light that can damage the retina. Omega-3 fatty acids, such as EPA and DHA, are essential for the functioning and development of the retina. They also have anti-inflammatory properties that can reduce the risk of developing AMD. The reduction in zinc was made to reduce the risk of side effects associated with the original formula’s high zinc content.
The removal of vitamin A was based on the finding that the original formula provided more than enough vitamin A, which can be harmful in large doses. The addition of vitamin D was based on recent studies that have shown that vitamin D deficiency is associated with an increased risk of developing AMD.
Overall, the AREDS 2 formula was found to reduce the risk of developing advanced AMD by up to 20% in people with intermediate or advanced AMD and to have no significant effect on the development or progression of cataracts. The formula is now widely available over the counter and is recommended for people over the age of 50 who are at risk of developing AMD or have intermediate or advanced AMD.
Conclusion
The AREDS formulas have been a significant breakthrough in the field of eye health and have helped to reduce the risk of developing advanced AMD in millions of people worldwide. Both the original and AREDS 2 formulas are widely available and have been proven to be effective in reducing the risk of AMD. However, it is important to note that the formulas are not a cure for AMD and that they cannot reverse the effects of the disease. Therefore, regular eye exams and early detection are still essential for the prevention and treatment of AMD.
Ingredients Found in AREDS 2
As we age, our eyesight is one of the first things that deteriorates. However, recent studies have shown that taking supplements that contain specific ingredients can help protect our eyes and even improve our vision. One of the most popular formulations is known as AREDS 2, which contains a blend of vitamins, minerals, and other essential nutrients that have been found to promote eye health. Here are some of the key ingredients found in AREDS 2:
Vitamin C
Vitamin C is an essential nutrient that plays a crucial role in maintaining the health of our eyes. It is an antioxidant that helps prevent damage to the cells in our eyes caused by free radicals. Free radicals are molecules that can cause oxidative stress and damage to our cells. Vitamin C is also important for the production of collagen, a protein that helps maintain the structure of our eyes.
In AREDS 2, the amount of vitamin C included is 500 milligrams. This is more than what is typically recommended for daily intake, but it is still within safe limits. It is important to note that too much vitamin C can cause adverse effects such as nausea, diarrhea, and stomach cramps. Therefore, it is important to take the recommended dosage and to consult with a healthcare professional before starting any new supplements.
Vitamin E
Another key ingredient of AREDS 2 is vitamin E, which is also an antioxidant that helps protect our eyes from oxidative stress. Vitamin E works in combination with vitamin C to enhance its antioxidant properties. It also plays a role in the formation of red blood cells and helps maintain the proper functioning of our immune system.
In AREDS 2, the amount of vitamin E included is 400 international units (IU). This is also within safe limits, but it is important to note that excessive amounts of vitamin E can interfere with blood clotting and increase the risk of bleeding disorders.
Zinc
Zinc is a mineral that is essential for many biological functions, including the health of our eyes. It helps maintain the structure of various eye tissues and is involved in the production of the pigment melanin, which protects our eyes from harmful UV rays. Zinc is also important for the absorption and metabolism of vitamin A, which is another essential nutrient for eye health.
In AREDS 2, the amount of zinc included is 80 milligrams. This is a relatively high amount, but it is necessary for the formulation to be effective. It is important to note that excessive amounts of zinc can cause adverse effects such as nausea, vomiting, and diarrhea, as well as interfere with the absorption of other essential nutrients such as copper.
In addition to these three key ingredients, AREDS 2 also contains other important nutrients such as lutein, zeaxanthin, and omega-3 fatty acids. Lutein and zeaxanthin are antioxidants that help protect our eyes from harmful blue light and UV rays. They are also important for maintaining the health of the macula, the part of our eye responsible for central vision. The omega-3 fatty acids included in AREDS 2 are important for maintaining healthy blood vessels and reducing inflammation, both of which are important for eye health.
Overall, AREDS 2 is a well-researched formulation that has been shown to be effective in promoting eye health and reducing the risk of age-related macular degeneration. It is important to note, however, that supplements should not be used as a replacement for a healthy diet and lifestyle. Consult with your healthcare professional to determine if AREDS 2 is right for you, and always follow the recommended dosage and precautions.
The Role of Lutein and Zeaxanthin in AREDS 2
The Age-Related Eye Disease Study 2 (AREDS 2) is a clinical trial initiated by the National Eye Institute in the USA to investigate the dietary supplements’ role in reducing the risk of developing age-related macular degeneration (AMD). The study identified a combination of nutrients that helped protect the eyes from the progression of AMD, including lutein and zeaxanthin, which are carotenoids found in dark leafy greens and other brightly colored fruits and vegetables.
The AREDS 2 study revealed that the addition of lutein and zeaxanthin to the original AREDS formula, which contained vitamins C and E, zinc, and copper, can reduce the progression of advanced AMD by 18 percent. Despite their similar chemical structures, lutein and zeaxanthin have different but complementary functions in the eye. Lutein is found predominantly in the macular pigment, while zeaxanthin is concentrated near the center of the macula.
Lutein and zeaxanthin help to prevent AMD by shielding the retina from blue light, a high-energy wavelength of light that can damage the cells in the macula. Retinal cells are also protected from oxidative stress, which can lead to inflammation and vision impairment. Macular pigment density determines the degree of protection provided by lutein and zeaxanthin. Individuals with low macular pigment density are at a higher risk of developing AMD.
While the body cannot produce lutein and zeaxanthin on its own, they can be obtained through the diet or supplements. Green leafy vegetables such as kale and spinach are good sources of lutein and zeaxanthin, as are orange peppers, corn, and egg yolks. Unfortunately, many people do not consume adequate levels of these essential nutrients. AREDS 2 formula contains 10 mg of lutein and 2 mg of zeaxanthin.
Lutein and zeaxanthin have been shown to have a positive effect on visual function in people with AMD. Studies suggest that lutein and zeaxanthin supplementation can improve contrast sensitivity, which is a measure of the ability to distinguish between light and dark objects. Individuals with AMD who take lutein and zeaxanthin supplements may experience enhanced vision and better color perception, although more research is needed.
In conclusion, the AREDS 2 study has identified a combination of vitamins, minerals, and carotenoids, including lutein and zeaxanthin, that can help protect the eyes from AMD. Lutein and zeaxanthin play a critical role in preventing retinal damage caused by oxidative stress and blue light exposure. People who do not consume enough lutein and zeaxanthin in their diets may benefit from AREDS 2 formula supplements to help reduce the risk of developing AMD. Consult your eye doctor before starting any supplement regimen to ensure it is safe and appropriate for you.
