Synopsis

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

Flavonoids are a diverse group of polyphenolic compounds found abundantly in fruits, vegetables, and other plant-derived foods. Their use in supporting the lymphatic system is primarily grounded in scientific evidence, though research is ongoing and somewhat limited compared to other body systems. Flavonoids possess notable anti-inflammatory, antioxidant, and vascular-protective properties. These effects are believed to be beneficial for the lymphatic system, which is responsible for fluid balance, immune function, and the removal of waste products from tissues.

Several clinical studies and reviews have investigated specific flavonoids such as diosmin, hesperidin, and rutin in the management of chronic venous insufficiency and lymphedema. For example, micronized purified flavonoid fraction (MPFF), which contains diosmin and hesperidin, has been shown to reduce edema, improve lymphatic tone, and decrease the symptoms of lymphatic insufficiency. These effects are thought to occur through the strengthening of capillary walls, reduction of capillary permeability, and modulation of inflammatory pathways. Some randomized controlled trials and meta-analyses support the use of certain flavonoids in the treatment of lymphedema, although the effect sizes are modest and more research is needed.

In summary, there is a moderate level of scientific evidence supporting the use of flavonoids for lymphatic health, particularly in the context of edema and lymphatic insufficiency. However, further high-quality research is necessary to fully validate their efficacy and to establish optimal dosing regimens.
