- 01Vitamin CModerate78% match
Vitamin C is required for collagen synthesis in blood vessel walls, so correcting a low intake can improve capillary integrity.
SuggestedBuffered vitamin C tablets - 02Grape Seed ExtractLimited66% match
Grape seed proanthocyanidins (OPCs) may strengthen capillary walls and reduce fragility, with supportive but limited human evidence.
SuggestedOPC-standardized grape seed extract - 03Pine Bark ExtractLimited62% match
Maritime pine bark proanthocyanidins are used to support capillary resistance and microvascular function, though nosebleed-specific data are sparse.
SuggestedStandardized maritime pine bark extract - 04QuercetinLimited57% match
Quercetin is a flavonoid that may help stabilize capillaries and reduce vascular permeability, but direct evidence for nosebleeds is minimal.
SuggestedQuercetin dihydrate capsules - 05Vitamin K1Limited55% match
Vitamin K1 supports normal clotting factor production, which is relevant only when bleeding stems from a vitamin K deficiency.
SuggestedVitamin K1 (phylloquinone) softgels
