Cranberry Extract Health Benefits

1. Prevent abnormal cell growth

Phytochemicals present in cranberries have potential anti-cancer activity. Cranberries are rich in polyphenols which are fantastic antioxidants. A rich supply of antioxidant compounds to neutralize the threat of free radical molecules (7). In fact, various in vitro and in vivo studies suggest that the anthocyanin, procyanidin, and flavonol components of cranberries may exert anti-cancer effects (8). Cranberry extracts and powders reduce inflammation and can help to prevent or reduce growth of various types of cancers, including cancers of the breast, cervix, ovary, colon, esophagus, prostate, brain, liver, lung, mouth, rectum, and stomach, as well as leukemia, lymphoma, and melanoma (9). 

2. Helps with Immunity

The nutrients and bioactive compounds contained in cranberries help improve immune function and help reduce infections. According to a 2013 study, consuming cranberry helped improve the function of epithelial cells, which serve as the first line of defense against infections and compounds in cranberry juice were found to have a positive impact on immunity and may help reduce flu symptoms (10). Additionally, cranberries are a rich source of vitamin C, which is important for optimal health because vitamin C, also known as ascorbic acid, is a water-soluble vitamin meaning our bodies do not have the capacity to store it and has been scientifically proven to maintain the normal functioning of the immune system, especially during and following exercise sessions among others (11). 

3. Promote Heart Health

Growing evidence suggest favorable effects of cranberry intake on blood pressure,  cholesterol profile, endothelial function, glucoregulation, inflammation, and oxidative stress that contribute to the reduction of cardiometabolic risk factors (12). Cranberries contain flavonoids that can reduce the oxidation of LDL cholesterol in men. High levels of oxidized LDL can lead to development of cardiovascular diseases. Supplementing your diet with cranberry extract may help lower the risk of such diseases since these polyphenols reduce the risk of developing cardiovascular disease by reducing blood pressure, fighting inflammation, and preventing platelet build-up (13). In fact, a study conducted among abdominally obese men found that cranberry consumption is linked to higher levels of HDL cholesterol in the body, hence, eating flavonoid-rich foods like cranberries is a good way to protect cardiovascular health (14). 

4. Prevents UTI

Proanthocyanidin, a compound found in cranberries, helps prevent UTIs by preventing the bacteria E. coli from sticking into the lining of the bladder and urethra hampering it from growing, taking over, and eventually infecting the lower urinary tract (15). A 2012 study with 1616 subjects found that cranberry products have a protective effect against UTIs and help reduce the risk of UTIs among women with a history of it (16). Since researchers believe that cranberries help to prevent bacteria latching onto the lining of the urinary tract, which stops them from multiplying, cranberry juice appears to be effective for preventing UTI’s (17). A study published in the American Journal of Clinical Nutrition further supports that cranberry prevents UTIs in women with a history of UTIs and took a cranberry drink or a placebo drink daily for six months (18). At the end of the six month period, those who took the cranberry drink had fewer UTIs (19). 

5. Promotes Gum Health

Cranberry helps prevent Streptococcus mutans, which is an oral bacteria that contributes to tooth decay and cavities from sticking to teeth, according to a 2015 study (20). In another 2015 study published in the same year, a mouthwash containing 0.6 percent cranberry was found to be as effective as a standard mouthwash used to control the bacteria in your mouth (21). Moreover, according to research, components found in cranberries help fight cavities as they inhibit acid production and its compounds may also help prevent gum disease (22). An expert says that cranberry disrupts glucan from forming (23). Glucan is the building block of plaque, whose presence usually leads to tooth decay.
