Age-related macular degeneration (AMD) impacts vision, but vitamins and supplements can help slow its progression. Our guide offers insights on effective nutritional strategies for eye health.
Age-related macular degeneration (AMD) is a condition affecting the central portion of the retina, leading to vision challenges that can profoundly impact daily life. Vitamins and supplements have become an integral part of managing AMD by helping to slow the progression of the disease. For many individuals, understanding and incorporating the right nutritional support is key to preserving central vision.
AMD is primarily a disease that affects the macula, the central region of the retina responsible for sharp, straight-ahead vision. This condition is most common in older adults and is classified into different stages. Initially, many patients may exhibit tiny, yellow deposits called drusen under the retina, which, when they grow larger or more numerous, can signal early or intermediate AMD.
The dry form of AMD, which accounts for about 8 out of 10 cases, results from the gradual breakdown or thinning of the macula. Over time, this slow degeneration can lead to significant issues in the central part of your vision—affecting activities such as reading, driving, and recognizing faces. Although the changes can be subtle in the early stages, increased awareness and screening by our eye doctors are essential in catching AMD before it progresses further.
Unlike some eye conditions, AMD does not have a cure. However, research has shown that certain nutritional support strategies can slow its progression. This is why vitamins and supplements have become a central talking point when discussing AMD care.
Over the past decades, significant research has been dedicated to finding how specific nutrients can benefit patients with AMD. Comprehensive studies, such as the Age-Related Eye Disease Study (AREDS) and its follow-up AREDS2 study, have provided encouraging data that nutritional supplements can slow the progression of AMD. These studies have paved the way for using vitamins and minerals as an adjunct to traditional eye care.
The original AREDS formula consisted of vitamins C and E, beta-carotene, zinc, and copper, and it demonstrated that properly formulated supplements could reduce the risk of AMD progression in many patients. However, further research indicated that beta-carotene, particularly among those who smoke, could increase the risk of lung cancer. This led to the formulation of AREDS2 and a critical substitution—lutein and zeaxanthin replaced beta-carotene.
AREDS2 data showed that the updated formula not only eliminated the risks associated with beta-carotene but also provided an even better protective benefit for the eyes. Lutein and zeaxanthin are antioxidants that naturally occur in the retina and help protect against oxidative stress, contributing to a reduced risk of developing advanced AMD. Here’s the key: the right combination of vitamins and supplements can make a meaningful difference in preserving vision, especially for patients with early to intermediate signs of AMD.

When discussing vitamins and supplements for AMD, it is important to understand the individual roles played by each nutrient. The following components have garnered significant attention based on extensive research and clinical studies:
For some formulations beyond the classic AREDS or AREDS2 recommendations, additional nutrients like vitamin D3 and omega-3 fatty acids (sourced from fish oil) are sometimes included to further support overall eye health, especially for those who may not consume sufficient amounts through their diet. However, beta-carotene is typically excluded due to its associated risks in certain populations.
AREDS2 was designed with patient safety and increased efficacy in mind. One of the main changes from the original formula was the removal of beta-carotene—a nutrient that, while effective as an antioxidant, posed increased risks for individuals who smoked. In its place, lutein and zeaxanthin took the spotlight because these naturally occurring carotenoids also reside in the eye and have a protective effect.
The rationale behind this change was supported by extensive data collected over a decade. The updated formula demonstrated an approximately 26% reduction in the risk of progressing to late-stage AMD for certain individuals compared to those using the original formula. This is significant as slowing the progression from early to advanced AMD can make a tremendous difference in maintaining the quality of your central vision.
For current or past smokers, the AREDS2 formula is particularly important. Studies tracked participants for a long period after switching to the lutein/zeaxanthin formulation, and the outcomes clearly supported that avoiding beta-carotene eliminated the increased risk of lung cancer while still providing ocular benefits. These results reiterate that the switch in nutrient components was indeed the right choice and highlights how refining vitamin and supplement regimens can yield better, safer results.
