Synopsis

Rating (out of 5): 3

Phenolics, a broad class of plant compounds including flavonoids and related polyphenols, have been investigated for their potential benefits to capillary health. Scientific studies, especially in the context of bioflavonoids such as rutin, quercetin, and hesperidin, suggest that certain phenolics can strengthen capillary walls, reduce capillary fragility, and improve microcirculation. This is particularly relevant in conditions like chronic venous insufficiency and capillary hemorrhages, where increased capillary permeability and fragility play a role. The proposed mechanisms include antioxidant effects, inhibition of enzymes that degrade connective tissue, and modulation of inflammatory pathways.

Clinical trials and meta-analyses have found that flavonoid-rich extracts (such as those from citrus or buckwheat) can reduce symptoms like leg swelling and bruising, which are related to capillary stability. However, much of this research focuses on specific, well-characterized phenolics rather than "phenolics (unspecified)." Thus, while there is scientific validation for certain phenolics supporting capillary health, the evidence is less clear for the entire, unspecified class of phenolics. Overall, moderate scientific evidence exists for the use of some phenolics in supporting the capillaries, but claims regarding "phenolics (unspecified)" should be made with caution.
