Investigating Nutritional Strategies for Effective Management of Dry Age-Related Macular Degeneration
As seasoned optometrists, we frequently encounter inquiries from patients seeking effective strategies to safeguard 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 paramount, with an increasing volume of clinical research underscoring 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 ocular condition that profoundly impacts 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, affecting thousands of individuals each year.
There are two primary types of macular degeneration that individuals should be aware of:
- dry macular degeneration
This is the more prevalent variant, constituting approximately 90% of all cases. It involves a gradual thinning of the macular tissue, leading to a slow yet steady decline in central vision over time. - Wet Macular Degeneration
This type 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 addressed promptly.
What Are the Consequences of Ineffective Treatment for Macular Degeneration?
- Dry AMD may progress at a slow pace; however, if left untreated, it can ultimately lead to substantial vision loss over an extended period.
- Wet AMD necessitates immediate medical intervention to avert permanent damage to central vision.
What Treatment Options Are Available for Macular Degeneration?
- Wet AMD is typically managed with injections aimed at inhibiting the formation of leaky blood vessels.
- Dry AMD is addressed through a combination of lifestyle modifications and nutritional supplements that comply with the scientifically validated AREDS2 formula.
Why Is It Essential to Follow the AREDS2 Formula for Effective Treatment?
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 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.
- Incorporating lutein and zeaxanthin, two essential carotenoids specifically beneficial for macular health.
The outcome? A safer and more effective approach to slowing the progression of dry AMD.
Which Nutritional Supplements Align with AREDS2 Guidelines in Australia?
Two widely acknowledged 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.
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 Drawbacks of the Original Blackmores Macu-Vision?
This product lacks both lutein and zeaxanthin and does not adhere to the AREDS2 guidelines in any capacity. While it does offer some antioxidant support, it fails to deliver the essential nutrients required for maintaining optimal macular health.
Side-by-Side Comparison: Macutec vs Macu-Vision Plus

| 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) |

*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 Insights for Informed Decisions:
- Lutein & Zeaxanthin: Macutec Once Daily meets the AREDS2 recommendation precisely (10mg Lutein, 2mg Zeaxanthin), while Blackmores Macu-Vision Plus provides only half of these vital nutrients.
- Zinc: Although Macutec employs a lower 25 mg Zinc dosage, AREDS2 findings demonstrated that this quantity was equally effective and associated with fewer side effects compared to higher levels.
- Vitamin E Formulation: Macutec utilises dl-alpha tocopherol; while AREDS2 used natural d-alpha, this alternative is widely accepted and does not significantly affect most users.
- Manufacturing Standards: Macutec is Australian-made under pharmaceutical GMP and incorporates premium branded lutein (FloraGLO®) and zeaxanthin (Optisharp®), both of which were featured in the original AREDS2 trials.
Key Insights for Choosing the Right Supplement:
Macutec is proudly Australian-made, featuring premium branded carotenoids that are integral to the AREDS2 study, designed for convenient once-per-day dosing.
Macutec Once Daily delivers a precise alignment with the AREDS2 formula, containing full-strength lutein (10 mg) and zeaxanthin (2 mg) while reducing excessive zinc intake.
Macu-Vision Plus, although marketed as an AREDS-style supplement, provides merely half of the recommended L/Z dosage, lower antioxidant levels, and excess zinc that may be deemed unnecessary.
Which Supplement Should You Choose for Your Eye Health Needs?
Both supplements are formulated to slow the progression of dry macular degeneration; however, only one fully complies with the AREDS2 formula: Macutec Essentials. It offers:
- Full-strength, evidence-based ingredients
- Clinically validated effectiveness
- Excellent value and precise dosing
- Manufactured in Australia adhering to high-quality standards
