Synopsis

Source of validity: Scientific
Rating (out of 5): 3

A fruit and vegetable blend (proprietary) is often included in supplements targeting the eyes due to the presence of various phytonutrients, vitamins, and antioxidants found naturally in fruits and vegetables. Scientific evidence supports the role of specific nutrients—such as vitamin C, vitamin E, beta-carotene, lutein, and zeaxanthin—in maintaining eye health and potentially reducing the risk of age-related macular degeneration (AMD) and cataracts. The Age-Related Eye Disease Study (AREDS and AREDS2) notably demonstrated that supplementation with antioxidants (including some derived from fruits and vegetables) plus zinc slowed the progression of advanced AMD in at-risk populations.

However, the term "fruit and vegetable blend (proprietary)" is vague, and the actual composition can differ widely between products. While whole fruits and vegetables have been associated with better eye health in epidemiological studies, the evidence for concentrated proprietary blends is less robust unless the blend is standardized for known effective compounds (such as lutein and zeaxanthin). Some blends may include extracts from bilberry, spinach, kale, or other sources known for their eye-supportive compounds, but unless specified, scientific validation is moderate rather than strong. In summary, while there is a scientific basis for the use of certain fruit and vegetable-derived nutrients for eye health, the evidence for all proprietary blends as a category is moderate.
