Investigating Nutritional Strategies for Addressing Dry Age-Related Macular Degeneration
As seasoned optometrists, we frequently receive inquiries from patients seeking effective strategies to protect or enhance their vision, particularly in relation to age-related conditions such as macular degeneration. The importance of nutrition and supplementation in sustaining optimal eye health is critical, and an increasing volume of clinical research underscores their essential role in managing dry age-related macular degeneration (AMD).
In this comprehensive analysis, 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 condition that critically impacts the macula, the central area of the retina responsible for delivering clear, high-definition vision. This degenerative condition stands as one of the principal causes of severe vision loss across Australia, affecting thousands of individuals each year and presenting a significant public health challenge.
There are two main forms of macular degeneration:
- Dry Macular Degeneration
This is the more prevalent type, making up nearly 90% of all cases. It is characterised by a gradual thinning of the macular tissue, which leads to a slow yet steady decline in central vision over the years. - Wet Macular Degeneration
This variant is less common but significantly more severe. It occurs when abnormal blood vessels proliferate and leak fluid or blood beneath the macula, often resulting in sudden, irreversible vision loss if not treated promptly.
What Are the Consequences of Ineffective Treatment for Macular Degeneration?
- Dry AMD may progress at a slow pace, but if left untreated, it can culminate in substantial vision loss over an extended period.
- Wet AMD necessitates immediate medical intervention to avert permanent damage to central vision.
What Are the Standard Treatment Approaches for Macular Degeneration?
- Wet AMD is generally managed through injections that aim to halt the growth of leaking blood vessels, preserving vision.
- Dry AMD is addressed through a combination of lifestyle modifications and nutritional supplements that are aligned 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 transformed our understanding of how nutritional support can play a vital role in combating AMD. The second study, AREDS2, refined the supplement formulation by:
- Excluding beta-carotene, which has been associated with a heightened risk of lung cancer among smokers.
- Modifying zinc levels to safer yet equally impactful amounts.
- Incorporating lutein and zeaxanthin, two essential macular carotenoids that contribute to eye health.
The outcome? A safer and more effective strategy for decelerating the progression of dry AMD.
Which Supplements Meet AREDS2 Guidelines in Australia?
Two well-regarded supplement options include:
1. Macutec Once Daily (by Stiltec – Proudly Australian Made)
Key Ingredients Compliant 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 ensure optimal absorption and efficacy.
Fully adheres to the AREDS2 formula for effective 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 to enhance nutrient uptake.
Contains only half the recommended dose of lutein and zeaxanthin as per AREDS2 guidelines
What Are the Limitations of the Original Blackmores Macu-Vision?
This product lacks both lutein and zeaxanthin and does not comply with AREDS2 guidelines in any aspect. While it offers some antioxidant support, it fails to deliver the essential nutrients required for sustaining optimal macular health, thus limiting its effectiveness in preventing vision deterioration.
Comparative Evaluation: Macutec vs Macu-Vision Plus

*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 Analysis and Insights:
- Lutein & Zeaxanthin: Macutec Once Daily meets the AREDS2 recommendation precisely (10mg Lutein, 2mg Zeaxanthin), whereas Blackmores Macu-Vision Plus provides only half that amount.
- Zinc: While Macutec utilises a lower dosage of 25 mg Zinc, the AREDS2 findings indicated that this amount was equally effective and associated with reduced 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 impact most users.
- Manufacturing Standards: Macutec is Australian-made under strict pharmaceutical GMP and features premium branded lutein (FloraGLO®) and zeaxanthin (Optisharp®), both of which were utilised in the original AREDS2 trials, ensuring high quality.
Crucial Considerations for Supplement Selection:
Macutec is also Australian-made, incorporating premium branded carotenoids that are part of the AREDS2 study, offering a convenient once-daily dosage for optimal compliance.
Macutec Once Daily presents a precise alignment with the AREDS2 formula, containing full-strength lutein (10 mg) and zeaxanthin (2 mg), while limiting excessive zinc intake that could pose health risks.
Macu-Vision Plus, although marketed as an AREDS-style supplement, provides only half of the recommended L/Z dosage, lower antioxidant levels, and excess zinc that may be unnecessary for effective treatment.
