Investigating Nutritional Support Strategies for Addressing Dry Age-Related Macular Degeneration
As seasoned optometrists, we frequently encounter inquiries from patients regarding effective strategies to protect or enhance their vision, particularly when facing age-related challenges such as macular degeneration. The importance of nutrition and supplementation in sustaining optimal eye health is paramount, and an expanding body of clinical research underscores their essential role in managing dry age-related macular degeneration (AMD).
In this comprehensive assessment, we will compare two leading products available in the Australian market: Macutec Once Daily and Blackmores Macu-Vision Plus.
Diving into the Fundamentals of Macular Degeneration
Macular degeneration is a degenerative condition that progressively impacts the macula, the central area of the retina crucial for delivering clear, high-resolution vision. This ailment ranks among the leading causes of severe vision loss in Australia, affecting thousands of individuals every year.
There are two main types of macular degeneration:
- Dry Macular Degeneration
This form is more prevalent, representing around 90% of all cases. It entails a gradual thinning of the macular tissue, leading to a slow but consistent decline in central vision over time. - Wet Macular Degeneration
This variant is less common but significantly more severe. It arises when abnormal blood vessels proliferate and leak fluid or blood beneath the macula, frequently resulting in sudden, irreversible vision loss if not treated promptly.
What Are the Consequences of Neglecting Effective Treatment for Macular Degeneration?
- Dry AMD may develop gradually, 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 aimed at inhibiting the development of leaking blood vessels.
- Dry AMD treatment involves a blend of lifestyle modifications and nutritional supplements that align with the scientifically backed AREDS2 formula.
Why Is It Essential to Follow the AREDS2 Formula for Treatment?
The Age-Related Eye Disease Studies (AREDS and AREDS2) have transformed our comprehension of how nutritional support can be vital in addressing AMD. The second study, AREDS2, refined the composition of the supplements by:
- Removing beta-carotene, which has been associated with an increased risk of lung cancer in smokers.
- Modifying zinc levels to safer yet equally effective amounts.
- Incorporating lutein and zeaxanthin, two vital macular carotenoids.
The outcome? A safer and more efficacious strategy for decelerating the progression of dry AMD.
Which Supplements Meet AREDS2 Guidelines in Australia?
Two highly regarded supplement options encompass:
1. Macutec Once Daily (by Stiltec – Proudly Australian Made)
Key Ingredients Aligned 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.
Fully complies with the AREDS2 formula
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.
Contains only half the recommended dose of lutein and zeaxanthin according to AREDS2
What Are the Shortcomings of the Original Blackmores Macu-Vision?
This product lacks both lutein and zeaxanthin and does not meet AREDS2 guidelines in any aspect. While it provides some antioxidant support, it fails to deliver the essential nutrients required for maintaining optimal macular health.
Comparative Overview: Macutec vs Macu-Vision Plus
| Ingredient | Macutec Once Daily | Macu-Vision Plus | AREDS2 Recommended Dosage |
|---|---|---|---|
| Vitamin C | 500 mg | 250 mg | 500 mg |
| Vitamin E | 400 IU (as dl-alpha tocopheryl acetate) | 200 IU | 400 IU |
| Zinc (as Zinc Oxide) | 25 mg | 40 mg | 80 mg* |
| Copper (as Cupric Oxide) | 2 mg | 1 mg | 2 mg |
| Lutein | 10 mg (FloraGLO® Lutein) | 5 mg | 10 mg |
| Zeaxanthin | 2 mg (Optisharp® Zeaxanthin) | 1 mg | 2 mg |
| Capsules per day | 1 softgel | 1 tablet | 1 dose |
| AREDS2 Formula Compliance | Full Match |
Partial (half dose L/Z, low C/E) |
Based on NEI AREDS2 Formula |
*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 Key Insights:
- Lutein & Zeaxanthin: Macutec Once Daily meets the AREDS2 guideline exactly (10mg Lutein, 2mg Zeaxanthin), whereas Blackmores Macu-Vision Plus only provides half.
- Zinc: While Macutec employs a lower 25 mg Zinc dosage, AREDS2 findings indicated that this level was equally effective and associated with fewer side effects compared to higher amounts.
- Vitamin E Composition: Macutec utilises dl-alpha tocopherol; although AREDS2 used natural d-alpha, this form is an accepted alternative that does not significantly affect most users.
- Manufacturing Standards: Macutec is Australian-made under pharmaceutical GMP and features premium branded lutein (FloraGLO®) and zeaxanthin (Optisharp®), both of which were integral to the original AREDS2 trials.
Essential Considerations for Choosing Supplements:
Macutec is also Australian-made, incorporating premium branded carotenoids that are part of the AREDS2 research, crafted for convenient once-daily dosing.
Macutec Once Daily offers a precise alignment with the AREDS2 formula, including full-strength lutein (10 mg) and zeaxanthin (2 mg), while minimising excessive zinc intake.
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 not be necessary.
The Ultimate Choice: Which Supplement Is Best for Your Needs?
Both supplements aim to decelerate the progression of dry macular degeneration, but only one fully adheres to the AREDS2 formula: Macutec Essentials. It provides:
- Full-strength, evidence-based ingredients
- Clinically validated effectiveness
- Superior value and precise dosing
- Manufactured in Australia to stringent quality standards
For these reasons, Eyes by Design exclusively stocks Macutec Essentials, which we confidently endorse to our patients on the Central Coast and beyond.
Available in-store or for delivery across Australia.

Frequently Asked Questions About Macutec Once Daily vs Macu-Vision Plus
What Is the AREDS2 Formula and Why Is It Important for Eye Health?
AREDS2 represents a clinically validated combination of vitamins and minerals that have demonstrated the ability to slow the progression of dry age-related macular degeneration. This formula includes vitamin C, vitamin E, zinc, copper, lutein, and zeaxanthin. Supplements that comply with this formulation, such as Macutec Essentials, offer the most evidence-based protection for maintaining macular health.
What Is the Role of Macutec Once Daily in Eye Care?
Macutec Once Daily is specifically formulated to support eye health in individuals diagnosed with dry age-related macular degeneration. It is based on the findings from the AREDS2 clinical research and aims to slow the advancement of the disease by protecting the macula from oxidative damage.
Can Supplements Like Macutec or Macu-Vision Cure Macular Degeneration?
No, these supplements cannot cure the condition. However, they can significantly decelerate the progression of dry macular degeneration and may aid in preserving vision for a longer period. Early intervention and consistent usage are key factors in achieving the best possible outcomes.
What Sets Macutec Once Daily Apart from Other Macular Supplements?
Macutec Once Daily contains all the validated AREDS2 components in a convenient once-daily capsule format. It utilises high-quality lutein and zeaxanthin identical to those used in the clinical trials and is produced in Australia under stringent pharmaceutical Good Manufacturing Practice standards.
How Do Lutein and Zeaxanthin Contribute to Macular Health?
Lutein and zeaxanthin are natural pigments found in the macula. They are crucial in forming the macular pigment, and sufficient intake is associated with enhanced macular pigment density. This increase aids in filtering harmful blue light and shields retinal tissue from oxidative stress.
Which Supplement Is Most Suitable If I Already Have Advanced Dry Macular Degeneration?
Macutec Once Daily is the ideal option if you are looking for an AREDS2-compliant supplement that includes full-strength ingredients. It is specifically designed for patients diagnosed with moderate to advanced dry AMD who wish to slow its progression.
