- 01Fish OilLimited68% match
Omega-3 fatty acids support endothelial function and may reduce vasospasm frequency, with some benefit reported in primary Raynaud.
SuggestedFish oil providing about 2 to 4 g combined EPA and DHA daily, with food - 02L-ArginineLimited64% match
L-arginine is a nitric oxide precursor that promotes vasodilation, which may improve peripheral blood flow during cold-induced vasospasm.
SuggestedL-arginine, 2 to 3 g daily, often split into two doses - 03L-CitrullineLimited62% match
L-citrulline is converted to arginine and helps sustain nitric oxide production, which supports vasodilation and peripheral perfusion.
SuggestedL-citrulline, 3 to 6 g daily - 04Ginkgo BilobaLimited60% match
Ginkgo may improve microcirculation and reduce platelet aggregation, which has shown modest reductions in Raynaud attack frequency in some trials.
SuggestedStandardized ginkgo extract (EGb 761 type), 120 to 240 mg daily - 05Magnesium GlycinateLimited57% match
Magnesium acts as a natural calcium antagonist that promotes smooth muscle relaxation and vasodilation, which may ease vasospasm.
SuggestedMagnesium glycinate, 200 to 400 mg in the evening - 06Vitamin B3Limited55% match
Niacin causes vasodilation and flushing, which is theorized to transiently improve peripheral blood flow.
SuggestedNiacin (immediate-release), low starting dose under clinician guidance
