PreserVision AREDS 2 is a specialized eye vitamin and mineral supplement designed to support eye health, particularly for individuals at risk of or already experiencing age-related macular degeneration (AMD). This comprehensive guide dives deep into what PreserVision AREDS 2 is, its ingredients, benefits, potential side effects, and how it fits into a broader eye care strategy.
Why This Matters: As we age, the risk of eye diseases like AMD increases. AMD can lead to significant vision loss. Proper nutrition, including supplements like PreserVision AREDS 2, can play a vital role in slowing its progression and maintaining optimal eye health. Understanding this supplement is crucial for anyone concerned about preserving their vision.
Quick Summary of PreserVision AREDS 2
PreserVision AREDS 2 is based on the Age-Related Eye Disease Study 2 (AREDS2) conducted by the National Eye Institute (NEI). The formula aims to replicate the beneficial nutrient combination found in the study that demonstrated a reduced risk of AMD progression.
The Science Behind PreserVision AREDS 2 and the AREDS/AREDS2 Studies
The Age-Related Eye Disease Studies (AREDS) and (AREDS2) were groundbreaking clinical trials that provided substantial evidence regarding the role of specific nutrients in mitigating the progression of AMD. Here’s a detailed look at these studies and their implications:
AREDS (Age-Related Eye Disease Study)
- Purpose: To evaluate the effect of high doses of antioxidants (Vitamin C and Vitamin E), beta-carotene, and zinc on the progression of AMD and cataract.
-
Participants: Over 3,600 participants aged 55-80 with varying stages of AMD.
-
Key Findings:
- The original AREDS formula (Vitamin C, Vitamin E, beta-carotene, and zinc) significantly reduced the risk of advanced AMD by about 25% in individuals with intermediate or advanced AMD.
- The study also showed a reduction in the risk of vision loss.
AREDS2 (Age-Related Eye Disease Study 2)
-
Purpose: To further refine the original AREDS formula to potentially improve its effectiveness and safety. Specifically, it sought to answer questions about beta-carotene, lutein, zeaxanthin, and omega-3 fatty acids.
-
Participants: Over 4,200 participants aged 50-85 with varying stages of AMD.
-
Key Changes and Findings:
- Beta-Carotene Replacement: The study found that lutein and zeaxanthin could replace beta-carotene, which was associated with an increased risk of lung cancer in smokers.
- Omega-3 Fatty Acids: Adding omega-3 fatty acids (DHA and EPA) did not provide additional benefit in reducing the risk of advanced AMD.
- Zinc Dosage: Lowering the zinc dosage did not significantly impact the effectiveness, allowing for a potential reduction in side effects.
Why These Studies Matter
The AREDS and AREDS2 studies provide the scientific foundation for using specific nutrient combinations to slow the progression of AMD. PreserVision AREDS 2 is formulated based on the findings of these studies, aiming to deliver a proven and effective combination of nutrients.
| Nutrient | AREDS Formula (Original) | AREDS2 Formula |
|---|---|---|
| Vitamin C | 500 mg | 500 mg |
| Vitamin E | 400 IU | 400 IU |
| Beta-Carotene | 15 mg | Replaced |
| Lutein | N/A | 10 mg |
| Zeaxanthin | N/A | 2 mg |
| Zinc | 80 mg | 80 mg (Often Lowered) |
| Copper | 2 mg | 2 mg |
| Omega-3 Fatty Acids | N/A | Not Included |
It’s important to note that current formulations of PreserVision AREDS 2 exclude Beta-Carotene.
Impact on Clinical Practice
The results of the AREDS and AREDS2 studies have profoundly influenced clinical practice in ophthalmology. Eye care professionals often recommend AREDS2-based supplements to patients with intermediate or advanced AMD to reduce the risk of progression to advanced stages, thus preserving vision.
These studies highlight the critical role of evidence-based nutritional interventions in managing age-related eye diseases. By understanding the science behind AREDS 2, patients can make informed decisions about their eye health and work closely with their healthcare providers to develop personalized treatment plans.
Understanding the Ingredients of PreserVision AREDS 2
PreserVision AREDS 2 contains a specific combination of vitamins and minerals believed to be beneficial for eye health. Here’s a breakdown of each ingredient and its role:
- Vitamin C (Ascorbic Acid): A powerful antioxidant that helps protect cells from damage caused by free radicals. In the eyes, it’s thought to help protect the lens and retina. The formulation contains 500 mg.
- Vitamin E (dl-alpha Tocopheryl Acetate): Another antioxidant that helps protect cells from damage. Works synergistically with Vitamin C. The formulation contains 400 IU.
- Lutein: A carotenoid found in high concentrations in the macula (the central part of the retina responsible for sharp, detailed vision). Lutein helps filter high-energy blue light and acts as an antioxidant. The formulation contains 10 mg.
- Zeaxanthin: Another carotenoid that works alongside lutein to protect the macula. Like lutein, it helps filter blue light and provides antioxidant protection. The formulation contains 2 mg.
- Zinc (Zinc Oxide): Essential for many enzymatic reactions in the body and plays a role in maintaining healthy vision. Zinc helps transport Vitamin A from the liver to the retina to produce melanin, a protective pigment in the eyes. The formulation contains 80 mg (though some formulations now contain a lower dose).
- Copper (Cupric Oxide): Included to prevent copper deficiency, which can occur with high doses of zinc supplementation. The formulation contains 2 mg.
Important Note: The original AREDS formula included beta-carotene. However, AREDS2 found that lutein and zeaxanthin could replace beta-carotene, eliminating the risk of increased lung cancer in smokers associated with beta-carotene supplementation. Therefore, the current PreserVision AREDS 2 formula does not contain beta-carotene.
Dosage and Forms
PreserVision AREDS 2 is typically taken as two softgels daily, divided into morning and evening doses with meals. However, it is important to carefully read the label on the specific product purchased as formulations can vary.
Available Forms:
- Softgels: The most common form.
- Chewable Tablets: An alternative for those who have difficulty swallowing pills. (Check the formulation to ensure it matches the AREDS 2 recommendations.)
- Other Formulations: Some variations might include additional ingredients like omega-3 fatty acids. However, the core AREDS 2 ingredients (Vitamin C, Vitamin E, Lutein, Zeaxanthin, Zinc, and Copper) remain the foundation.
Always consult your eye care professional or healthcare provider before starting any new supplement regimen to ensure it is appropriate for your individual needs and medical history.
Who Should Consider Taking PreserVision AREDS 2?
PreserVision AREDS 2 is primarily recommended for individuals who have been diagnosed with intermediate to advanced AMD. It’s important to understand that it’s not a cure for AMD, but rather a supplement designed to slow its progression.
Here’s a breakdown of who might benefit:
- Individuals with Intermediate AMD: Those who have shown some signs of AMD but haven’t yet experienced significant vision loss. Specific signs an eye doctor will look for are the presence of medium-sized or large drusen (yellow deposits under the retina).
- Individuals with Advanced AMD in One Eye: Those who have advanced AMD in one eye but not the other may benefit from taking PreserVision AREDS 2 to help protect the remaining eye.
- Individuals with a Family History of AMD: While not a direct treatment, some individuals with a strong family history of AMD may consider discussing preventative measures, including supplements, with their eye doctor. However, this should be done under medical supervision.
Important Considerations:
- Smokers and Former Smokers: The original AREDS formula contained beta-carotene, which has been linked to an increased risk of lung cancer in smokers. PreserVision AREDS 2 does not contain beta-carotene, making it a safer option for smokers and former smokers.
- Age: AMD is more common in older adults, typically those over the age of 50.
- Overall Health: It’s essential to consider your overall health and any existing medical conditions before taking any new supplement.
