Cranberry [SEP] Phytochemicals
Raw cranberries, cranberry juice and cranberry extracts are a source of polyphenols – including proanthocyanidins, flavonols and quercetin. These phytochemical compounds are being studied in vivo and in vitro for possible effects on the cardiovascular system, immune system and cancer. However, there is no confirmation from human studies that consuming cranberry polyphenols provides anti-cancer, immune, or cardiovascular benefits. Potential is limited by poor absorption and rapid excretion. Cranberry juice contains a high molecular weight non-dializable material that is under research for its potential to affect formation of plaque by "Streptococcus mutans" pathogens that cause tooth decay. Cranberry juice components are also being studied for possible effects on kidney stone formation.
