Small, but Mighty: the original Super Fruit

Every year, a new “superfood” seems to dominate the conversation. But, cranberries, dubbed the “original super fruit” have been on center stage since before the days of the pilgrims. From reducing your risk of everything from cavities to urinary tract infections (UTIs), cranberries have long been lauded for their medicinal properties. But research shows that not all cranberry supplements are created equal.

Research shows that not all cranberry is equal. 

Health Benefits of Cranberry

Cranberries are more than a delicious accompaniment to Thanksgiving dinner or your favorite cocktail. Research has linked these little red berries to a staggering number of health benefits, including:

  • Help cleanse the urinary tract, which could lower risk of UTIs and bladder infections
  • Improving immune function4
  • Decreasing blood pressure4
  • Preventing certain types of cancer 4
  • Offering a good source of Vitamins C, E, K and Fiber4
  • Providing high levels of flavonoids and phytonutrients—naturally occurring compounds with powerful antioxidant and antimicrobial properties4

Cranberry & UTIs

Despite a host of health benefits, cranberries are most often associated with urinary health and UTI protection. Once more of a home remedy, recent research has helped boost cranberry’s credibility in modern science. A 1998 Rutgers University study credited proanthocyanidins (PACs), a flavonoid abundant in cranberries, with preventing E. coli, the bacteria responsible for 90% of UTIs, from attaching to the walls of the urinary tract. Instead, the bacteria are flushed from the tract, preventing urinary tract infections.2 And most recently, a study through Boston University found cranberries to reduce symptomatic UTIs by nearly 40% in women with recurrent UTIs.3

Not all Cranberry is Created Equal

It’s true, cranberries contain antioxidants that can add a layer of protection from UTI. But, researchers are quick to point out that not all cranberry sources pack the same punch. And that there are ways to incorporate cranberry into your diet beyond just drinking cranberry juice. Researchers at the Texas A&M Health Science Center College of Medicine and House contend that while cranberry supplements pack the potency to prevent bacteria from attaching to the urinary tract, drinking cranberry juice alone isn’t enough.1

“Cranberry juice, especially the juice concentrates you find at the grocery store, will not treat a UTI or bladder infection. It can offer more hydration and possibly wash bacteria from your body more effectively, but the active ingredient in cranberry is long gone by the time it reaches your bladder.”

–Dr. Timothy Boone, PhD, vice dean of the Texas A&M Health Science Center College of Medicine in Houston

The same study indicated that cranberry pills, can reduce the risk of a UTI up to 50%.What makes cranberry pills like AZO Cranberry® a better choice than other cranberry sources? AZO Cranberry® products are backed by science. They are made with clinically-proven, Pacran®, a super-concentrated whole fruit cranberry powder and includes early black cranberries, rich in bacteria blocking PACs.4  Unlike other cranberry supplements, Pacran® pulls from the entire fruit—the seeds, the skin, the pulp and the juice to tap every last bit of the superfood’s benefits. Their high concentration lets you reap the powerful benefits of antioxidant-rich cranberries with a fraction of the sugar and calories of cranberry juice. It’s a safe and convenient way to get your daily cranberry.

Plus, AZO Cranberry® offers a second line of defense. It contains a probiotic, which helps nurture your body’s “good” bacteria and protect against UTI-causing bacteria.
