Cranberries are small, tart, bright-red berries that are a popular treat, especially during the holiday season.

They’re packed with antioxidants and provide many health benefits.

Cranberry pills, which are made from dried, powdered cranberries, offer an easy way to enjoy these benefits without having to eat cranberries every day.

This articles reviews the most common uses for cranberry pills, their potential health benefits and side effects, and recommended dosage.

What Are Cranberry Pills?

Cranberry pills are small tablets or capsules made from dried, powdered cranberries.

They provide many of the same health benefits as fresh cranberries.

Some cranberry pills also contain other ingredients, such as vitamin C or probiotics, to enhance their effects.

Specifics vary by brand, but one serving of cranberry pills is typically equivalent to an 8-ounce (237-ml) glass of pure cranberry juice.

Cranberry pills are available over the counter at drugstores or can be purchased online.

SUMMARY

Cranberry pills are made from dried, powdered cranberries and may contain additional ingredients to enhance their effects. They can be purchased over the counter and provide many of the same benefits as fresh cranberries or cranberry juice.

They Help Prevent Urinary Tract Infections

Cranberry pills may be an effective way to prevent recurring urinary tract infections (UTIs).

Cranberries contain compounds called proanthocyanidins, which prevent E. coli bacteria from attaching to the lining of your urethra and bladder (1Trusted Source2Trusted Source).

If bacteria can’t stick to the tissues, they are unable to multiply and cause an infection.

Several studies have found that taking cranberry pills containing 36 mg of proanthocyanidins every day for two months can significantly reduce the frequency of UTIs, especially in women (3Trusted Source4Trusted Source5Trusted Source6Trusted Source).

Other studies have found no beneficial effects in different populations, including elderly people living in nursing homes or those with bladder disorders (7Trusted Source8Trusted Source9Trusted Source10Trusted Source).

It is unclear whether cranberry pills are as effective as traditional antibiotics at preventing UTIs, as studies have found conflicting results (11Trusted Source12Trusted Source).

These mixed conclusions could be due to differences in study design or because cranberry may not be as effective at preventing the 25–35% of UTIs caused by fungi or bacteria other than E. coli (13Trusted Source14Trusted Source15Trusted Source16Trusted Source).

SUMMARY

Cranberry pills contain proanthocyanidins, which prevent E. colibacteria from attaching to the urinary tract and causing painful infections.

They Contain Powerful Antioxidants

Cranberries are full of antioxidants, which protect your body from damage caused by free radicals.

Free radical damage has been linked to many chronic illnesses, including heart disease and diabetes (17Trusted Source18Trusted Source).

Interestingly, cranberries contain more antioxidants than many other commonly eaten fruits and berries (19Trusted Source).

Some of the compounds in cranberries are even more effective than vitamin E, one of the body’s most important antioxidants, at fighting free radicals (20Trusted Source21Trusted Source).

Since cranberry pills are made from dried, powdered cranberries, they contain an even higher concentration of antioxidants than fresh fruit or prepared products like cranberry sauce or cranberry jelly (22Trusted Source).

Even though cranberry pills are made from dried, powdered cranberries, their antioxidant content remains active. In fact, taking cranberry supplements every day for eight weeks has been shown to significantly reduce markers of oxidative stress in the body (23Trusted Source).

SUMMARY

Cranberries and cranberry pills contain very high levels of antioxidants, which protect your body from free radical damage linked to various chronic illnesses.

Other Potential Benefits

While research on cranberry pills is somewhat limited, studies on cranberry juice and cranberry extracts suggest they have following benefits:

More studies are needed to determine whether cranberry pills would have the same benefits, but studies on other cranberry products are promising.

SUMMARY

Cranberry juice and extracts may boost immunity, lower blood sugar in people with diabetes and protect against cancer, heart disease, stomach ulcers, cavities and gum disease. Cranberry pills may have similar effects, but more research is needed.

Cranberry Pills Don’t Have Added Sugar

Since cranberries are so tart, many cranberry recipes and products contain lots of sugar.

The American Heart Association recommends that women and men consume no more than 25 and 37.5 grams of added sugar each day, respectively (43Trusted Source).

Just one-fourth cup of canned cranberry sauce or one cup of a cranberry juice cocktail contains over 10 grams of added sugar, making it difficult to stay within these guidelines.

Eating large amounts of added sugar has been linked to the development of heart disease and diabetes, so it is wise to keep your intake in check (44Trusted Source45Trusted Source46Trusted Source).

Cranberry pills can be a great way to enjoy the health benefits of cranberries without the negative effects of added sugar.

SUMMARY

Many cranberry products contain a lot of sugar to mask cranberry’s naturally tart taste, but eating too much added sugar is bad for your health. Cranberry pills offer a way to experience the health benefits of cranberries without consuming extra sugar.

Side Effects and Interactions

Cranberry pills are relatively well tolerated, but a handful of people have reported stomach discomfort, abdominal pain or increased urination after taking the pills (9Trusted Source11Trusted Source23Trusted Source47Trusted Source).

Cranberries are also high in salicylic acid, a naturally occurring anti-inflammatory compound (48Trusted Source49Trusted Source).

Anyone who is allergic or sensitive to salicylates, including aspirin, may want to avoid cranberry pills since an adverse reaction is theoretically possible (50Trusted Source).

Furthermore, those with a history of kidney stones should consult their doctor before taking cranberry supplements. Some research suggests that they may increase the risk of developing calcium-oxalate stones (51Trusted Source52Trusted Source53Trusted Source).

There have also been a few reported cases of cranberry supplements increasing the effects of the blood-thinning drug Warfarin, so it is important to consult your doctor or pharmacist before starting any new supplements (54Trusted Source55Trusted Source).

SUMMARY

Cranberry pills are relatively safe but may cause stomach upset in some people. Anyone with a sensitivity or allergy to salicylates, a history of kidney stones or those taking the blood-thinning drug Warfarin may want to avoid cranberry supplements.

Recommended Dosages

There is no standard dosage for cranberry pills, and amounts can vary widely between brands.

In general, research has found that taking 500–1,500 mg of dried cranberry powder per day prevents urinary tract infections. Moreover, 1,200 mg of dried cranberry juice powder can reduce oxidative stress (11Trusted Source23Trusted Source56Trusted Source57Trusted Source).

Newer research has focused on the concentration of proanthocyanidins, as they are one of the main active ingredients in cranberry pills.

Products containing at least 25% proanthocyanidins or 36 mg per serving appear to be the most effective at preventing urinary tract infections (58Trusted Source59Trusted Source60Trusted Source61Trusted Source).

More research is needed to determine the ideal dosage for cranberry pills for various purposes.

SUMMARY

There is no official recommended dosage for cranberry pills, but taking at least 500 mg of powdered cranberry or 36 mg of proanthocyanidins per day appears to prevent urinary tract infections.

The Bottom Line

Cranberry pills are a great option for people who want to experience some of the health benefits of cranberries without having to eat them every day.

They are packed with antioxidants and can help reduce the frequency of urinary tract infections in some people.

Also, they may promote heart health, improve blood sugar control, boost immunity and protect against cancer, cavities and stomach ulcers.

Dosages of up to 1,500 mg per day are safe for most.

Cranberry pills may be worth a try for those who get frequent urinary tract infections or want some extra antioxidant support.
