The use of vegetable and fruit blends to support or treat high triglycerides has some scientific foundation, though the evidence is not robust or specific to proprietary blends. Various epidemiological and clinical studies have shown that increased intake of fruits and vegetables is associated with improved lipid profiles, including lower triglyceride levels. This effect is largely attributed to the high content of dietary fiber, antioxidants (such as polyphenols and vitamin C), and phytochemicals in fruits and vegetables, which can positively influence lipid metabolism and reduce oxidative stress and inflammation.

However, the evidence for proprietary "vegetable and fruit blends" (as opposed to whole foods or well-characterized extracts) is limited. While some small studies suggest that concentrated fruit and vegetable powders or extracts may modestly lower triglycerides, these results are not consistent, and products vary widely in their composition and quality. Most guidelines for managing high triglycerides emphasize whole food dietary patterns rich in fruits and vegetables, rather than supplements or blends.

In summary, the general scientific consensus supports increased fruit and vegetable intake for cardiovascular health and triglyceride management, but the direct evidence supporting proprietary blends specifically is modest at best, justifying a moderate evidence rating (2/5).
