Investigating Nutritional Support Strategies for Managing Dry Age-Related Macular Degeneration
As experienced optometrists, we frequently encounter inquiries from patients regarding effective strategies to safeguard or enhance their vision, particularly in relation to age-related conditions such as macular degeneration. The role of nutrition and supplementation in sustaining optimal eye health is paramount, and an increasing body of clinical research underscores their crucial function in managing dry age-related macular degeneration (AMD).
In this thorough evaluation, we will meticulously 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 ailment that significantly impacts the macula, the central area of the retina responsible for delivering clear, high-resolution vision. This condition ranks as one of the primary causes of severe vision loss in Australia, affecting thousands of individuals each year.
There are two main forms of macular degeneration:
- Dry Macular Degeneration
This is the predominant type, constituting roughly 90% of all cases. It involves a gradual thinning of the macular tissue, resulting in a slow yet consistent decline in central vision over time. - Wet Macular Degeneration
This type is less common but considerably more severe. It arises when abnormal blood vessels proliferate and leak fluid or blood beneath the macula, often leading to sudden, irreversible vision loss if not addressed promptly.
What Are the Consequences of Not Effectively Treating Macular Degeneration?
- Dry AMD may develop slowly, yet if left untreated, it can culminate in significant vision loss over an extended period.
- Wet AMD necessitates immediate medical intervention to avert irreversible damage to central vision.
What Are the Standard Treatment Options for Macular Degeneration?
- Wet AMD is generally managed through injections aimed at curbing the growth of leaking blood vessels.
- Dry AMD treatment typically involves a combination of lifestyle modifications and nutritional supplements adhering to the scientifically validated 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 understanding of how nutritional support can be vital in mitigating the effects of AMD. The second study, AREDS2, refined the supplement composition by:
- Eliminating beta-carotene, which has been associated with an increased risk of lung cancer in smokers.
- Modifying zinc levels to safer yet equally effective amounts.
- Introducing lutein and zeaxanthin, two critical macular carotenoids.
The outcome? A safer and more effective approach for decelerating the progression of dry AMD.
Which Supplements Meet AREDS2 Guidelines in Australia?
Two well-known supplement options are:
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.
Fully adheres to 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 respect. While it provides some antioxidant support, it fails to deliver the essential nutrients required for maintaining optimal macular health.
Comparative Evaluation: 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 Insights:
- Lutein & Zeaxanthin: Macutec Once Daily meets the AREDS2 recommendation precisely (10mg Lutein, 2mg Zeaxanthin), while Blackmores Macu-Vision Plus offers only half.
- 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 uses dl-alpha tocopherol; while AREDS2 utilised natural d-alpha, this form is a widely accepted substitute that does not significantly detract from user experience.
- Manufacturing Standards: Macutec is Australian-made under pharmaceutical GMP, featuring premium branded lutein (FloraGLO®) and zeaxanthin (Optisharp®), both of which were utilised in the original AREDS2 trials.
Crucial Considerations for Supplement Selection:
Macutec is also Australian-made, incorporating premium branded carotenoids that align with the AREDS2 study, designed for convenient once-per-day dosing.
Macutec Once Daily offers a precise alignment with the AREDS2 formula, featuring full-strength lutein (10 mg) and zeaxanthin (2 mg), while minimising excessive zinc intake.
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 necessary.
The Final Verdict: Which Supplement Should You Choose?
Both supplements aim to slow the progression of dry macular degeneration, but only one fully complies with the AREDS2 formula: Macutec Essentials. It delivers:
- Full-strength, evidence-based ingredients
- Clinically validated effectiveness
- Exceptional value and precise dosing
- Manufactured in Australia to high-quality standards
For these reasons, Eyes by Design exclusively offers Macutec Essentials, which we confidently recommend to our patients on the Central Coast and beyond.
Available in-store or for delivery throughout Australia.

Frequently Asked Questions about Macutec Once Daily versus Macu-Vision Plus
What Is the AREDS2 Formula and Why Is It Important for Eye Health?
AREDS2 represents a clinically validated blend of vitamins and minerals that have been shown to slow the progression of dry age-related macular degeneration. This formula includes vitamin C, vitamin E, zinc, copper, lutein, and zeaxanthin. Supplements that conform to this formula, such as Macutec Essentials, provide 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 progression of the disease by shielding the macula from oxidative damage.
Can Supplements Such as 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 critical factors in achieving the best possible outcomes.
What Sets Macutec Once Daily Apart from Other Macular Supplements?
Macutec Once Daily incorporates all the validated AREDS2 components in a convenient once-daily capsule format. It utilises high-quality lutein and zeaxanthin identical to those used in clinical trials and is manufactured in Australia adhering to stringent pharmaceutical Good Manufacturing Practice standards.
How Do Lutein and Zeaxanthin Enhance Overall Macular Health?
Lutein and zeaxanthin are natural pigments located in the macula. They play an essential role in forming the macular pigment, and adequate intake is linked to increased macular pigment density. This enhancement serves to filter harmful blue light and protects retinal tissue from oxidative stress.
Which Supplement Is Most Suitable If I Already Have Advanced Dry Macular Degeneration?
Macutec Once Daily is the best option if you seek an AREDS2-compliant supplement that contains full-strength ingredients. It is specifically designed for patients diagnosed with moderate to advanced dry AMD who wish to slow its progression.
