Investigating Nutritional Support Approaches for Effective Management of Dry Age-Related Macular Degeneration
As seasoned optometrists, we frequently encounter inquiries from patients regarding effective strategies to protect or improve their vision, particularly in the context of age-related conditions such as macular degeneration. The importance of nutrition and supplementation in sustaining optimal eye health cannot be underestimated, with an expanding array of clinical studies underscoring their crucial role in managing dry age-related macular degeneration (AMD).
In this comprehensive evaluation, we will compare two prominent products available in the Australian market: Macutec Once Daily and Blackmores Macu-Vision Plus.
Comprehensive Understanding of Macular Degeneration
Macular degeneration is a progressive eye condition that significantly impacts the macula, the central section 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 main types of macular degeneration:
- Dry Macular Degeneration
This is the more prevalent form, constituting approximately 90% of all cases. It involves a gradual degradation of the macular tissue, resulting in a slow, steady decline in central vision over time, which can be distressing for those affected. - Wet Macular Degeneration
This variant is less common but significantly more serious. It arises when abnormal blood vessels develop and leak fluid or blood under the macula, often leading to sudden and irreversible vision loss without prompt medical intervention.
What Are the Consequences of Failing to Treat Macular Degeneration Effectively?
- Dry AMD may progress gradually, but if left untreated, it can culminate in substantial vision loss over a prolonged period, impacting daily life and activities.
- Wet AMD necessitates immediate medical attention to avert permanent damage to central vision, underscoring the urgency of timely treatment.
What Are the Common Therapeutic Approaches for Macular Degeneration?
- Wet AMD is typically addressed through injections aimed at inhibiting the growth of leaky blood vessels, a critical step in preserving vision.
- Dry AMD is managed through a combination of lifestyle modifications and nutritional supplements that adhere to the scientifically validated AREDS2 formula.
Why Is Following the AREDS2 Formula Essential for Effective Treatment?
The Age-Related Eye Disease Studies (AREDS and AREDS2) have transformed our comprehension of how nutritional support can play a vital role in combating AMD. The second study, AREDS2, refined the composition of supplements by:
- Excluding beta-carotene, which has been associated with an increased risk of lung cancer in smokers, thereby enhancing safety.
- Adjusting zinc levels to safer yet equally effective dosages, ensuring optimal patient outcomes.
- Incorporating lutein and zeaxanthin, two critical macular carotenoids essential for eye health.
The outcome? A more secure and effective strategy for decelerating the progression of dry AMD, ensuring better patient care.
Which Supplements Align with AREDS2 Guidelines in Australia?
Two well-regarded supplement options include:
1. Macutec Once Daily (by Stiltec – Proudly Manufactured in Australia)
Key Ingredients That Comply 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 a meal.
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 a meal.
Contains only half the recommended dose of lutein and zeaxanthin as per AREDS2
What Are the Drawbacks of the Original Blackmores Macu-Vision?
This product does not include both lutein and zeaxanthin, and it fails to meet AREDS2 guidelines in any respect. While it does provide some antioxidant support, it lacks the essential nutrients required for sustaining optimal macular health, making it less effective.
Comparative Analysis: Macutec Once Daily Versus Macu-Vision Plus

|---|---|---|---|
| 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 Compliance |
Partial Compliance (half dose of L/Z, low C/E) |
Based on NEI AREDS2 Formula |
*AREDS2 research indicated that lower zinc doses (25 mg) were equally effective and associated with fewer side effects compared to higher amounts of 80 mg, making it a safer option for patients.
Ingredient Breakdown and Key Insights:
- Lutein & Zeaxanthin: Macutec Once Daily meets the AREDS2 recommendation precisely (10mg Lutein, 2mg Zeaxanthin), while Blackmores Macu-Vision Plus provides only half of the recommended dosage, which may impact efficacy.
- Zinc: Although Macutec employs a lower 25 mg Zinc dosage, AREDS2 findings demonstrated that this amount was equally effective and correlated with fewer side effects compared to higher levels, ensuring patient safety.
- Vitamin E Formulation: Macutec utilises dl-alpha tocopherol; while AREDS2 used natural d-alpha, this form is a widely accepted alternative that does not significantly affect most users.
- Manufacturing Standards: Macutec is Australian-made under stringent pharmaceutical GMP and includes premium branded lutein (FloraGLO®) and zeaxanthin (Optisharp®), both of which were used in the original AREDS2 trials, ensuring quality and effectiveness.
Essential Insights for Choosing the Right Supplement:
Macutec is also Australian-manufactured, featuring high-quality branded carotenoids that are included in the AREDS2 study, designed for convenient once-per-day dosing to enhance compliance.
Macutec Once Daily offers a precise alignment with the AREDS2 formula, containing full-strength lutein (10 mg) and zeaxanthin (2 mg), while minimising excessive zinc intake, which can be beneficial for overall health.
Macu-Vision Plus, despite being marketed as an AREDS-style supplement, only provides half of the recommended L/Z dosage, lower antioxidant levels, and excess zinc that could be unnecessary, making it less ideal for patients.
