About
Freeze-dried cranberries are whole or powdered fruits of Vaccinium macrocarpon that have been lyophilized to remove moisture while preserving bioactive polyphenols, proanthocyanidins, anthocyanins, and dietary fiber. They are used as a nutrient-dense food ingredient, snack, and dietary supplement ingredient valued for antioxidant, anti-inflammatory, and urinary-tract health properties.
Safety summary
Freeze-dried cranberries are widely regarded as safe for the general adult population, with no established ADI and a long history of conventional food use recognized by the FDA. EFSA assessed cranberry extract powder (a concentrated derivative) and found no safety concerns at typical intake levels. High intake may interact with warfarin (anticoagulant) due to polyphenol content, and the natural oxalate load warrants caution in individuals prone to kidney stones.
