Examining Nutritional Support Strategies for Managing Dry Age-Related Macular Degeneration
As knowledgeable optometrists, we frequently receive inquiries from patients about effective strategies to protect or enhance their vision, particularly when confronting age-related conditions such as macular degeneration. The importance of nutrition and supplementation in preserving optimal eye health is paramount, and an increasing number of clinical studies underscore their essential role in managing dry age-related macular degeneration (AMD).
In this comprehensive evaluation, we will compare two prominent products available in the Australian market: Macutec Once Daily and Blackmores Macu-Vision Plus.
Grasping the Fundamentals of Macular Degeneration
Macular degeneration is a progressive eye condition that significantly impacts the macula, which is the central part of the retina responsible for delivering clear, high-resolution vision. This condition stands as one of the leading causes of severe vision loss in Australia, affecting thousands of individuals each year and leading to a decline in their quality of life.
There are two main forms of macular degeneration:
- Dry Macular Degeneration
This is the more prevalent type, accounting for approximately 90% of all diagnosed cases. It involves a gradual thinning of the macular tissue, resulting in a slow but steady decline in central vision over time, often unnoticed by the individual until significant damage occurs. - Wet Macular Degeneration
This type, while less common, is considerably more serious. It occurs when abnormal blood vessels grow and leak fluid or blood beneath the macula, often leading to sudden, irreversible vision loss if not treated promptly and effectively.
What Are the Dangers of Inadequate Treatment for Macular Degeneration?
- Dry AMD may progress slowly, but if left untreated, it can result in significant vision loss over an extended period, thereby impacting daily activities and overall quality of life.
- Wet AMD necessitates immediate medical attention to avert permanent damage to central vision, highlighting the importance of early diagnosis and intervention.
What Are the Most Common Treatment Approaches for Macular Degeneration?
- Wet AMD is typically addressed through injections aimed at inhibiting the growth of leaky blood vessels, which can help preserve vision if administered quickly.
- Dry AMD is managed through a combination of lifestyle modifications and nutritional supplements that align with the scientifically validated AREDS2 formula.
Why Is Following the AREDS2 Formula Essential for Treatment Success?
The Age-Related Eye Disease Studies (AREDS and AREDS2) have fundamentally changed our understanding of how nutritional support can effectively combat AMD. The second study, AREDS2, refined the composition of supplements by:
- Removing beta-carotene, which has been associated with a higher risk of lung cancer in smokers, thus improving safety for at-risk populations.
- Adjusting zinc levels to safer yet equally effective amounts, thereby minimising potential side effects.
- Incorporating lutein and zeaxanthin, two vital macular carotenoids that play a crucial role in eye health.
The outcome? A safer and more effective method for slowing the progression of dry AMD, ensuring patients receive the most beneficial support.
Which Supplements Align with AREDS2 Guidelines in Australia?
Two prominent supplement options recognised in the market include:
1. Macutec Once Daily (by Stiltec – Proudly Australian Made)
Key Ingredients That Comply with AREDS2 Guidelines:
- Vitamin C – 500mg
- Vitamin E – 400 IU
- Zinc Oxide – 25mg
- Copper – 2mg
- Lutein – 10mg
- Zeaxanthin – 2mg
Recommended dosage: One tablet daily with food to optimise absorption.
Fully adheres to the AREDS2 formula, ensuring comprehensive eye health support.
2. Blackmores Macu-Vision Plus
- Vitamin C – 250mg
- Vitamin E – 200 IU
- Zinc Oxide – 40mg
- Copper – 1mg
- Lutein – 5mg
- Zeaxanthin – 1mg
Recommended dosage: One tablet daily with food for enhanced efficacy.
Contains only half the recommended dose of lutein and zeaxanthin according to AREDS2, potentially limiting its effectiveness.
What Are the Shortcomings of the Original Blackmores Macu-Vision?
This product lacks both lutein and zeaxanthin and does not comply with AREDS2 guidelines in any capacity. While it does provide some antioxidant support, it fails to deliver the essential nutrients that are critical for maintaining optimal macular health and preventing further degeneration.

*AREDS2 research indicated that lower zinc doses (25 mg) were equally effective and resulted in fewer side effects compared to higher amounts of 80 mg.
Ingredient Breakdown and Key Insights:
- Lutein & Zeaxanthin: Macutec Once Daily meets the AREDS2 recommendation precisely (10mg Lutein, 2mg Zeaxanthin), whereas Blackmores Macu-Vision Plus only provides half of this dosage.
- Zinc: Although Macutec uses a lower 25 mg Zinc dosage, AREDS2 findings have shown that this amount is equally effective and linked to fewer side effects compared to higher levels.
- Vitamin E Formulation: Macutec employs dl-alpha tocopherol; while AREDS2 used natural d-alpha, this form is a widely accepted substitute that does not significantly affect most users.
- Manufacturing Standards: Macutec is Australian-made under pharmaceutical GMP and includes premium branded lutein (FloraGLO®) and zeaxanthin (Optisharp®), both of which were utilised in the original AREDS2 trials, ensuring high-quality standards.
Crucial Considerations for Supplement Selection:
Macutec is also Australian-made, featuring premium branded carotenoids that are integral to the AREDS2 study, formulated for convenient once-daily dosing.
Macutec Once Daily provides a precise alignment with the AREDS2 formula, containing full-strength lutein (10 mg) and zeaxanthin (2 mg), while reducing excessive zinc intake, making it a well-balanced option.
Macu-Vision Plus, while marketed as an AREDS-style supplement, contains only half of the recommended L/Z dosage, lower antioxidant levels, and excess zinc, which may be unnecessary for most users.
