Synopsis

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

A Fruit & Vegetable Blend is often included in supplements aimed at supporting eye health due to the presence of naturally occurring vitamins, minerals, and phytonutrients with known benefits for vision. Notably, fruits and vegetables are rich sources of antioxidants such as vitamin C, vitamin E, beta-carotene (a precursor to vitamin A), lutein, and zeaxanthin. Scientific studies indicate that lutein and zeaxanthin, found in green leafy vegetables and some fruits, accumulate in the retina and help filter harmful blue light, reducing the risk of age-related macular degeneration (AMD) and cataracts. The Age-Related Eye Disease Study (AREDS) and subsequent trials demonstrated that diets high in certain antioxidant nutrients can slow the progression of AMD in at-risk individuals.

However, the evidence for broad fruit and vegetable blends is rated a 3 because most research isolates specific nutrients or foods (like spinach for lutein/zeaxanthin or carrots for beta-carotene) rather than generic dried blends. While epidemiological studies consistently show that increased fruit and vegetable intake is associated with better eye health outcomes, direct intervention studies using unspecified blends are lacking. Thus, while it is scientifically plausible that a high-quality fruit and vegetable blend might support eye health due to its micronutrient and antioxidant content, more targeted research is needed to confirm benefits from supplement forms.
