About
Cranberry (Vaccinium macrocarpon) is a tart, red berry native to North America used as a whole fruit, juice, sauce, dried fruit, and concentrated extract in foods and dietary supplements. It is rich in polyphenols — including proanthocyanidins (PACs), anthocyanins, flavonols, and phenolic acids — valued for antioxidant, anti-adhesion, and potential cardiovascular properties.
Safety summary
Cranberries and cranberry extract powder are recognized as safe (GRAS) by the FDA and assessed as safe by EFSA as a novel food ingredient based on composition, clinical trials, and manufacturing data. High-dose cranberry consumption can increase urinary oxalate excretion, raising kidney stone risk in susceptible individuals. Cranberry products may potentiate the effect of anticoagulant drugs such as warfarin, requiring caution in patients on blood thinners.
