- Preventative Care: More individuals are proactively seeking ways to maintain and improve their health, including vision.
- Awareness of Nutrients: Greater awareness of the importance of vitamins and antioxidants for eye health is driving demand for supplements.
The Power of Harvard Research in Vision Supplements
Harvard Medical School and its affiliated institutions have conducted extensive research on the impact of nutrition on eye health. The Age-Related Eye Disease Study (AREDS) and AREDS2, supported by the National Eye Institute (NEI), have provided critical insights into the role of specific nutrients in reducing the risk of advanced AMD. Harvard’s contributions to understanding the pathogenesis of eye diseases have been instrumental in formulating effective vision supplements.
Key Findings from Harvard’s Research:
| Study | Key Nutrient(s) | Findings |
|---|---|---|
| AREDS | Vitamin C, Vitamin E, Beta-Carotene, Zinc, Copper | Showed that these nutrients reduced the risk of advanced AMD by about 25% and vision loss by 19%. |
| AREDS2 | Lutein, Zeaxanthin | Found that lutein and zeaxanthin are effective alternatives to beta-carotene and can further reduce the risk of advanced AMD. |
| Observational Studies | Omega-3 Fatty Acids | Suggested that high dietary intake of omega-3 fatty acids is associated with a reduced risk of developing AMD. |
Impact on Supplement Formulation:
The results of these studies have led to the development of vision supplements that include specific dosages of the nutrients proven to be effective in clinical trials. Supplements formulated based on AREDS2 guidelines are considered the gold standard for supporting eye health.
