The use of a Fruit & Vegetable Blend to support gum (periodontal) health has some scientific basis, primarily related to the antioxidant, anti-inflammatory, and micronutrient content of fruits and vegetables. Epidemiological studies have consistently shown that diets rich in fruits and vegetables are associated with better oral health outcomes, including reduced risk of periodontal disease. The rationale is that fruits and vegetables provide vitamin C, polyphenols, fiber, and other micronutrients that are essential for collagen synthesis, immune function, and the reduction of oxidative stress—all relevant to gum health.

Randomized controlled trials on specific "fruit & vegetable blends" are limited, but several studies indicate that increased intake of whole fruits and vegetables, or concentrated extracts, can decrease gum bleeding and inflammation. For example, vitamin C deficiency is a well-established risk factor for gingivitis and periodontitis, and supplementation improves gum health. Some polyphenols (from berries, grapes, etc.) have demonstrated anti-inflammatory and antimicrobial effects in the oral cavity. However, results can vary widely depending on the specific blend and dosage.

While more rigorous clinical research on standardized blends is needed, the general scientific consensus supports the idea that fruit and vegetable intake is beneficial for gum health. Thus, the use of a Fruit & Vegetable Blend for this purpose has scientific, though not conclusive, justification.
