AREDS 2 Vitamin Supplements and Wet AMD: What You Should Know

Wet age-related macular degeneration (wet AMD) is a leading cause of vision loss, and the number of people affected worldwide is rapidly increasing. Among evidence-based strategies to slow its progression, the AREDS 2 vitamin supplement regimen stands out for its scientific backing and practical accessibility. This in-depth article covers what AREDS 2 is, how it works in relation to wet AMD, potential side effects and interactions, limitations, and other important considerations for those aiming to maintain optimal eye health.

What Is AREDS 2?

AREDS 2 refers to a specific vitamin and mineral supplement formulation designed to slow the progression of age-related macular degeneration (AMD). It is named after the “Age-Related Eye Disease Study 2,” a major clinical trial sponsored by the National Institutes of Health.

To gain a deeper understanding of how vitamins and supplements can specifically aid in managing macular degeneration, it’s beneficial to explore our detailed guide on vitamins and supplements for eye health. This guide will provide insights into which nutrients play crucial roles and how they can potentially impact your vision positively.

The formula was developed after research showed that a carefully balanced combination of nutrients could help reduce the risk of AMD progression in those with intermediate or advanced disease in one eye. The AREDS 2 supplement is widely available over-the-counter and recommended for individuals at risk of significant vision loss due to AMD.

Specific Ingredients in the AREDS 2 Formula

Ingredient	Amount (per daily dose)
Vitamin C	500 mg
Vitamin E	400 IU
Copper (as cupric oxide)	2 mg
Zinc (as zinc oxide)	80 mg
Lutein	10 mg
Zeaxanthin	2 mg

Each ingredient in the AREDS 2 formula was selected for its role in promoting retinal health, acting as an antioxidant or supporting cellular structure and function in the eye .

How Does AREDS 2 Work for Wet AMD?

AMD occurs when the macula, the central part of the retina responsible for sharp, detailed vision, deteriorates. Wet AMD specifically involves abnormal blood vessel growth and leakage beneath the macula, leading to rapid vision loss.

For anyone seeking to optimize their eye health further or simply understand the broader landscape of essential nutrients, check out our comprehensive guide on eye health supplements. This resource dives into various supplements and vitamins, offering you a wealth of information that can aid your vision care journey.

Antioxidant properties: Vitamins C and E, as well as the carotenoids lutein and zeaxanthin, act to reduce oxidative stress on retinal cells, helping guard against further cellular damage.
Mineral support: Zinc plays a key role in retinal metabolism and is necessary for many enzymes in the eye. Copper is included to prevent deficiency due to high zinc intake .
Carotenoids protection: Lutein and zeaxanthin are concentrated in the macula, where they filter harmful blue light and counteract oxidative damage, two key drivers of AMD progression.

The AREDS 2 study found that this combination could reduce the risk of late-stage AMD progression by about 25% over a five-year period in individuals with intermediate disease or advanced disease in one eye .

Potential Side Effects of AREDS 2 Supplements

Though generally considered safe, AREDS 2 supplements can cause side effects in some individuals due to their high doses of certain vitamins and minerals.

Gastrointestinal upset such as mild nausea, diarrhea, or stomach discomfort.
Urinary tract issues (rare), due to zinc.
Changes in skin or hair color (rare), due to copper.
Elevated risk of bleeding in people on blood thinners, due to high vitamin E intake.

If you experience persistent or unusual symptoms after starting an AREDS 2 supplement, consult your healthcare provider promptly.

Possible Interactions with Other Medications or Supplements

It is important to inform your eye doctor or pharmacist about all other medications and supplements you are taking, since AREDS 2 contains high levels of certain nutrients.

For those interested in powerfully aligning their diet with eye health, consult our tailored strategies for eating right for dry AMD—where you'll discover how nutrition plays a pivotal role in your AMD management.

Zinc and copper: High doses of zinc can interfere with absorption of copper, leading to possible deficiency. This is why copper is included in the formula.
Vitamin E: High doses may enhance the effect of blood-thinning medications (e.g., warfarin) and increase the risk of bleeding.
Other multivitamins: Many multivitamins already contain vitamins C, E, and zinc—taking both could exceed safe limits.

Your healthcare provider can help you determine if adjustments need to be made to your supplement or medication regimen.

Current Limitations of AREDS 2 and Its Application

While AREDS 2 shows promise in delaying AMD progression, especially from intermediate to advanced stages, it is not a cure for AMD or a replacement for standard medical treatments, such as anti-VEGF injections for wet AMD. Additional considerations include:

A focus on a nutrient-rich diet can significantly enhance your eye health. For those curious about the potential benefits of Vitamin D and its link to macular degeneration, explore our insights on Vitamin D and its impact on eye health to understand its prevention strategies better.

Prevention not established: AREDS 2 has not been shown to prevent AMD from developing in people without signs of the disease.
No reversal: It slows, but does not reverse, existing vision loss.
Limited impact on early AMD: The benefits are greatest in individuals with intermediate AMD or advanced disease affecting one eye.
Not a substitute for ophthalmic care: Regular eye exams and medical management are still critical .

Other Supplements and Dietary Strategies for Wet AMD

Besides AREDS 2, several other nutrients and lifestyle changes may support overall eye health in AMD patients:

Omega-3 fatty acids: May have additional anti-inflammatory benefits for the retina, though large trials have not shown clear evidence of AMD slowing.
Vitamin D: Being studied for its potential antioxidant and immune-modulatory role.
B-complex vitamins: Important for vascular and neurological health; discussed as part of comprehensive dietary approaches.
Leafy green vegetables and fish: Rich in lutein, zeaxanthin, and omega-3s naturally; a nutrient-dense diet is generally recommended .
Lifestyle modifications: Quitting smoking, maintaining healthy blood pressure, and managing cardiovascular risk factors greatly reduce AMD risk and progression.

Who Should Take AREDS 2 Supplements?

AREDS 2 supplements are most beneficial for:

Those with intermediate AMD in one or both eyes (defined by clinical eye examination).
Individuals who have advanced AMD in one eye but not the other, to protect the unaffected eye.
People who have been specifically recommended to use them by an eye care specialist.

For those without AMD, especially younger, healthy individuals, there is no evidence these supplements prevent the disease and high doses of vitamins or minerals outside of medical advice are discouraged.

How to Use AREDS 2 Supplements

AREDS 2 supplements are available in capsule or softgel form. They can be found under various brand names, but it is important to verify that the formula matches the research-supported dosages.

General guidelines:

Take as directed—typically once or twice daily.
Review all current supplements with your doctor to avoid overdosing on any ingredient.
Monitor for possible side effects, especially if you are taking other high-dose vitamins or minerals.
Continue regular eye exams and follow your specialist’s AMD management plan.
