Does Preservision Areds 2 Help With Macular Degeneration?
Yes, Preservision AREDS 2 can significantly help slow the progression of intermediate to advanced age-related macular degeneration (AMD) in certain individuals. It provides essential nutrients but is not a cure and does not restore lost vision.
Understanding Age-Related Macular Degeneration (AMD)
Age-related macular degeneration (AMD) is a leading cause of vision loss in older adults. It affects the macula, the central part of the retina responsible for sharp, central vision needed for tasks like reading and driving. AMD comes in two forms: dry and wet. The dry form is more common and progresses slowly, while the wet form is less common but more aggressive, potentially leading to rapid vision loss. Understanding which type of AMD a patient has is crucial for determining appropriate treatment and management strategies.
The AREDS and AREDS2 Studies: A Breakthrough
The Age-Related Eye Disease Study (AREDS) and AREDS2 are landmark clinical trials that investigated the impact of specific nutrients on the progression of AMD. The original AREDS formula showed a significant reduction in the risk of advanced AMD. AREDS2 refined the formula, improving its efficacy and safety. These studies provided the scientific basis for recommending specific dietary supplements to individuals at risk of developing or progressing in their AMD.
Preservision AREDS 2: What’s Inside?
Preservision AREDS 2 is a dietary supplement formulated based on the AREDS2 study results. It contains:
- Lutein (10 mg)
- Zeaxanthin (2 mg)
- Vitamin C (500 mg)
- Vitamin E (400 IU)
- Zinc (80 mg)
- Copper (2 mg)
These nutrients act as antioxidants, helping to protect the cells in the macula from damage caused by free radicals.
How Preservision AREDS 2 Works
The nutrients in Preservision AREDS 2 work synergistically to support macular health. Lutein and Zeaxanthin are carotenoids that are concentrated in the macula and filter harmful blue light, protecting against oxidative damage. Vitamin C, Vitamin E, Zinc, and Copper are potent antioxidants that neutralize free radicals and support the health of the retinal cells. By supplementing with these nutrients, individuals can reduce their risk of AMD progression.
Who Should Consider Taking Preservision AREDS 2?
Preservision AREDS 2 is primarily recommended for individuals with intermediate or advanced AMD in one or both eyes. It is not generally recommended for individuals with early AMD or those with no signs of AMD. A thorough eye examination by an ophthalmologist or optometrist is crucial to determine the stage of AMD and whether Preservision AREDS 2 is appropriate.
Benefits of Taking Preservision AREDS 2
- Slows the Progression of AMD: The primary benefit is reducing the risk of advanced AMD by approximately 25% in individuals with intermediate to advanced stages.
- Protects Macular Health: The antioxidants help protect the macula from oxidative damage.
- Supports Overall Eye Health: While primarily aimed at AMD, the nutrients can contribute to overall eye health.
Potential Side Effects and Risks
While generally safe, Preservision AREDS 2 can cause some side effects. These can include:
- Gastrointestinal upset (nausea, diarrhea)
- Zinc-related issues (copper deficiency in some cases)
- Allergic reactions (rare)
It’s essential to discuss any existing medical conditions and medications with a healthcare provider before starting Preservision AREDS 2. High doses of zinc can interfere with the absorption of other medications.
Dosage and Administration
The recommended dosage is typically two capsules per day, taken with food. Splitting the dosage (one capsule twice a day) can help minimize gastrointestinal upset. Always follow the instructions on the product label or as directed by your eye care professional.
Common Mistakes to Avoid
- Taking it without proper diagnosis: Do not self-diagnose and start taking Preservision AREDS 2. Consult with an eye care professional first.
- Expecting it to cure AMD: Preservision AREDS 2 cannot cure AMD or restore lost vision.
- Ignoring a healthy lifestyle: Preservision AREDS 2 is most effective when combined with a healthy diet rich in fruits and vegetables, regular exercise, and smoking cessation.
The Importance of a Comprehensive Eye Exam
Regular eye exams are crucial for monitoring AMD and assessing the effectiveness of Preservision AREDS 2. Your eye care professional can track changes in your vision and macular health and adjust your treatment plan as needed.
The Future of AMD Treatment
Research continues to explore new treatments for AMD, including gene therapy and stem cell therapy. While these approaches are still in development, they offer hope for improved outcomes in the future. Does Preservision Areds 2 Help With Macular Degeneration? Yes, but it’s also just one piece of a continuously evolving AMD treatment landscape.
Alternatives to Preservision AREDS 2
While Preservision AREDS 2 is a well-established option, alternative AREDS2 formulations are available. Some may offer different dosages or delivery methods. It’s important to discuss these options with your doctor to determine the best choice for your individual needs. A healthy diet rich in antioxidants can also support eye health, but may not provide the same level of nutrients as a dedicated supplement.
Frequently Asked Questions (FAQs)
Is Preservision AREDS 2 a cure for macular degeneration?
No, Preservision AREDS 2 is not a cure for macular degeneration. It can help slow the progression of the disease in individuals with intermediate or advanced AMD, but it cannot restore vision that has already been lost.
Can I take Preservision AREDS 2 if I don’t have macular degeneration?
It’s not generally recommended to take Preservision AREDS 2 if you don’t have macular degeneration. The high doses of nutrients may not be necessary and could potentially lead to side effects. Consult with your doctor to determine if it’s appropriate for you.
How long does it take to see results from Preservision AREDS 2?
The benefits of Preservision AREDS 2 are realized over several years. It’s not a quick fix. The AREDS and AREDS2 studies showed a significant reduction in the risk of advanced AMD after several years of supplementation.
Can Preservision AREDS 2 improve my vision?
Preservision AREDS 2 is unlikely to improve your vision. Its primary purpose is to slow down the progression of macular degeneration and reduce the risk of advanced vision loss.
What if I miss a dose of Preservision AREDS 2?
If you miss a dose of Preservision AREDS 2, take it as soon as you remember. However, if it’s close to the time for your next dose, skip the missed dose and continue with your regular schedule. Do not double the dose to catch up.
Can I take Preservision AREDS 2 with other medications?
It’s essential to discuss all medications and supplements you are taking with your healthcare provider before starting Preservision AREDS 2. High doses of zinc can interact with certain medications.
Are there any dietary restrictions while taking Preservision AREDS 2?
There are no specific dietary restrictions while taking Preservision AREDS 2. However, a healthy diet rich in fruits, vegetables, and omega-3 fatty acids can further support eye health.
Can I get the same nutrients from food instead of taking Preservision AREDS 2?
While a healthy diet can provide many of the same nutrients, it may be difficult to obtain the high doses used in the AREDS2 formula from food alone. Preservision AREDS 2 provides a convenient and reliable way to ensure you are getting the recommended levels of these nutrients.
Is Preservision AREDS 2 covered by insurance?
Preservision AREDS 2 is generally not covered by insurance because it is considered a dietary supplement. However, some insurance plans may offer discounts on supplements.
What should I do if I experience side effects from Preservision AREDS 2?
If you experience side effects from Preservision AREDS 2, stop taking the supplement and consult with your healthcare provider. They can help determine if the side effects are related to the supplement and recommend alternative options.
How is Preservision AREDS 2 different from the original AREDS formula?
The AREDS2 formula replaced beta-carotene with lutein and zeaxanthin and reduced the amount of zinc. This was done because beta-carotene was linked to an increased risk of lung cancer in smokers, and high doses of zinc can cause side effects.
Does Preservision Areds 2 help with macular degeneration if I already have significant vision loss?
Does Preservision Areds 2 Help With Macular Degeneration even with significant loss? While it can still slow the progression of AMD, its impact on preventing further vision loss might be less pronounced compared to earlier stages. It’s crucial to discuss the potential benefits and realistic expectations with your eye doctor.
