Exploring Nutritional Support Strategies for Effective Management of Dry Age-Related Macular Degeneration
As experienced optometrists, we often receive numerous inquiries from patients who seek effective strategies to protect or enhance their vision, especially when dealing with age-related issues like macular degeneration. The significance of nutrition and supplementation in maintaining optimal eye health cannot be overstated, and a growing body of clinical research highlights their essential role in managing dry age-related macular degeneration (AMD).
In this comprehensive analysis, we will compare two leading products available in the Australian market: Macutec Once Daily and Blackmores Macu-Vision Plus.
Understanding the Fundamentals of Macular Degeneration and Its Impact
Macular degeneration is a progressive disorder that significantly affects the macula, the central area of the retina responsible for delivering sharp, high-resolution vision. This condition ranks among the leading causes of severe vision loss in Australia, impacting thousands of individuals every year, often resulting in a profound effect on their quality of life.
There are two primary forms of macular degeneration that warrant attention:
- Dry Macular Degeneration
This form is the more common type, accounting for approximately 90% of all cases. It involves a gradual thinning of the macular tissue, which leads to a slow but persistent decline in central vision over time, leaving individuals struggling with daily tasks. - Wet Macular Degeneration
This type, while less prevalent, is considerably more severe. It occurs when abnormal blood vessels form and leak fluid or blood beneath the macula, often resulting in sudden, irreversible vision loss if immediate medical intervention is not sought.
What Are the Risks Associated with Neglecting Effective Treatment for Macular Degeneration?
- Dry AMD may progress gradually, but if left untreated, it can result in significant vision loss over an extended timeframe, which could have devastating implications for daily activities.
- Wet AMD requires immediate medical intervention to prevent permanent damage to central vision, highlighting the necessity of early detection and treatment.
What Are the Most Common Treatment Strategies for Macular Degeneration?
- Wet AMD is commonly treated through injections that aim to inhibit the development of leaky blood vessels, effectively managing the condition and preserving vision.
- Dry AMD is typically managed through a blend of lifestyle modifications and nutritional supplements that comply with the scientifically validated AREDS2 formula, ensuring optimal support for eye health.
Why Is It Essential to Follow the AREDS2 Formula in Treatment?
The Age-Related Eye Disease Studies (AREDS and AREDS2) have revolutionised our understanding of how nutritional support can be crucial in combating AMD. The second study, AREDS2, improved the supplement composition by:
- Eliminating beta-carotene, which had been linked to an increased risk of lung cancer in smokers, ensuring a safer formulation.
- Modifying zinc levels to safer yet equally effective amounts, reducing the potential for side effects.
- Incorporating lutein and zeaxanthin, two essential macular carotenoids that play a significant role in eye health.
The end result? A safer and more effective approach to slowing the progression of dry AMD, providing patients with better options for managing their condition.
Which Nutritional Supplements Comply with AREDS2 Guidelines in Australia?

1. Macutec Once Daily (by Stiltec – Proudly Australian Made)
Key Ingredients That Align 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 for optimal absorption.
Fully adheres to the AREDS2 formula
2. Blackmores Macu-Vision Plus
- Vitamin C – 250mg

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 measurable aspect. Although it offers some antioxidant support, it fails to provide the essential nutrients required for maintaining optimal macular health, which is crucial for individuals at risk of vision loss.
Comparative Analysis: 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 Breakdown and Key Insights:
- Lutein & Zeaxanthin: Macutec Once Daily meets the AREDS2 recommendation precisely (10mg Lutein, 2mg Zeaxanthin), while Blackmores Macu-Vision Plus only provides half of the required amounts.
- Zinc: Although Macutec employs a lower 25 mg Zinc dosage, AREDS2 findings demonstrated that this amount was equally effective and associated with fewer side effects compared to higher levels.
- Vitamin E Formulation: Macutec utilises dl-alpha tocopherol; while AREDS2 utilised natural d-alpha, this form is a widely accepted substitute that does not significantly impact most users.
- Manufacturing Standards: Macutec is Australian-made under pharmaceutical GMP and incorporates premium branded lutein (FloraGLO®) and zeaxanthin (Optisharp®), both of which were utilised in the original AREDS2 trials.
Critical Considerations for Selecting Eye Health Supplements:
Macutec is also Australian-made, featuring high-quality branded carotenoids that are integral to the AREDS2 study, designed for convenient once-per-day dosing, ensuring ease of use for patients.
Macutec Once Daily offers a precise alignment with the AREDS2 formula, containing full-strength lutein (10 mg) and zeaxanthin (2 mg), effectively minimising excessive zinc intake that may not be necessary for all individuals.
Macu-Vision Plus, despite being marketed as an AREDS-style supplement, provides only half of the recommended L/Z dosage, lower antioxidant levels, and excess zinc that may not be beneficial for eye health.
