Among the many supplements out there, the Age-Related Eye Disease Study 2 (AREDS2) formula has received significant attention for its potential to slow the progression of AMD. This article delves into whether the AREDS2 formula is FDA approved, exploring the intricacies of dietary supplement regulation, the evidence behind AREDS2, and what consumers should know.
Understanding the FDA’s role in dietary supplement regulation
Before diving into the specifics of AREDS2, it’s crucial to understand the U.S. Food and Drug Administration’s (FDA) role in dietary supplement oversight. Unlike pharmaceuticals, which must receive FDA approval before being marketed, dietary supplements do not require pre-market approval. Instead, the FDA regulates these products under a different set of guidelines established by the Dietary Supplement Health and Education Act of 1994 (DSHEA).
Under DSHEA, manufacturers are responsible for ensuring that their products are safe and that any claims made about them are substantiated by adequate evidence. However, they do not need to obtain FDA approval before selling these products. The FDA’s role is primarily to monitor the market for unsafe products and take action against any supplement or claim that poses a risk to consumers or lacks scientific support.
The origins of the AREDS2 formula
One must first understand the formula’s origins to fully grasp the discussion surrounding AREDS2 and FDA approval. AREDS2 is an updated version of the original Age-Related Eye Disease Study (AREDS) formula, which was developed through a major clinical trial funded by the National Eye Institute (NEI), part of the National Institutes of Health (NIH). The original AREDS study aimed to investigate whether certain vitamins and minerals could reduce the risk of developing advanced AMD.
Following the initial study, AREDS2 sought to refine the formula by testing modifications that might improve its safety and efficacy. The AREDS2 formula typically includes vitamins C and E, zinc, copper, lutein, and zeaxanthin, elements chosen based on their potential antioxidant or eye health benefits.
Examining the evidence behind AREDS2
The Age-Related Eye Disease Study 2 (AREDS2) is a cornerstone of research in the field of ophthalmology, especially concerning age-related macular degeneration (AMD). Conducted by the National Eye Institute, this randomized, multi-center clinical trial was designed to assess the effects of specific nutrients on the progression of AMD and cataracts. The trial followed participants with varying stages of AMD, focusing on whether a modified combination of vitamins and minerals could offer protective benefits against advanced stages of the disease.
What do the study’s findings indicate?
The AREDS2 formula includes vitamins C and E, zinc, copper, lutein, and zeaxanthin. Lutein and zeaxanthin were of particular interest due to their presence in the macula and their potential to protect against harmful blue light and oxidative stress. The study’s findings indicated that participants at high risk for advanced AMD who followed the AREDS2 formula had a statistically significant reduction in the risk of AMD progression. This effect was particularly noted in individuals who were not already at the very advanced stages of the disease, highlighting the formula’s potential as a preventative measure rather than a cure.
It’s important to recognize limitations
Despite these positive outcomes, it’s important to recognize the limitations of the AREDS2 study, including its specific applicability to individuals with certain genetic backgrounds and dietary habits. Moreover, the long-term effects of high-dose supplementation on overall health were outside the study’s scope, emphasizing the need for ongoing research and personalized medical advice.
Navigating the landscape of dietary supplements and eye health
The dietary supplement market is vast and varied, with numerous products claiming to support eye health. For consumers, distinguishing between evidence-based formulas like AREDS2 and less substantiated claims can be daunting. When considering supplements for eye health, particularly for conditions like AMD, it’s essential to look for products that explicitly state they adhere to the AREDS or AREDS2 formula. This ensures that the supplement contains the specific combination of nutrients proven beneficial in clinical trials.
However, the presence of an AREDS2 label is not the sole factor to consider. The quality and dosage of ingredients can vary between products, and some may include additional components not covered by the original study. Therefore, it’s crucial for consumers to read labels carefully, verify the credibility of manufacturers, and ideally, choose products that have undergone third-party testing for quality and safety.
Consulting with a healthcare provider or a specialist in eye health before beginning any new supplement regimen is also advisable. This step is particularly important for individuals with pre-existing health conditions, as certain ingredients in eye health supplements could interact with medications or affect other aspects of health.

Beyond the question of FDA approval
While the AREDS2 formula itself is not FDA approved, as no dietary supplement is, the distinction may not be as significant as it seems at first glance. The more pertinent questions for consumers and healthcare providers revolve around the formula’s safety, efficacy, and whether it’s appropriate for an individual’s specific health profile.
