Cranberries contain citric, chinic, benzoic and oleic acids, vitamins C and P, carotene, saponins, amino acids, routine, quercetin, glycoside, microelements (iodine, iron, copper, manganese. They've been shown in some research, to have a role in supporting urinary tract health.
The cranberry fruit is a unique and rich source of bioactive polyphenol compounds. Cranberry constituents can exert beneficial effects on gingival and periodontal health by inhibiting inflammatory response, suppressing bacterial bioﬁlm formation, and reducing the activity of periopathogenic proteolytic enzymes.
In addition, the phenolic compounds found in cranberries can change the behaviour of harmful bacteria in the mouth without killing them. This is important because if the bacteria were killed, it could disrupt the balance of good and bad bacteria in the mouth, potentially leading to the growth of resistant bacteria.
Instead, cranberry phenols interfere with the virulence properties of harmful bacteria, making it more difficult for them to cause damage to teeth and gums. This helps to maintain the healthy balance of bacteria in the mouth and reduce the risk of oral health problems.
