How we compiled our list of the best cranberry supplements
The evaluation of supplements can be difficult, given the numerous different brands and lack of U.S. Food and Drug Administration (FDA) regulation.
Therefore it is important to research each supplement to find cranberry tablets or capsules best suited for your needs. Luckily, we have gone through careful analysis and identified top supplements based on these factors:
| Price-to-value | Quality | Proanthocyanidins (PAC) content | Production method | Additional ingredients |
| $12.49–26 | Use of independent lab testing and current Good Manufacturing Practices | 36 mg is considered an adequate dosage per day | Organic vs. non-organic | Addition of other active ingredients |
- Price-to-value. Identifying high-quality products that provide significant worth without breaking the bank.
- Quality. Supplements subjected to third-party lab testing and manufactured in facilities certified to be compliant with current Good Manufacturing Practices (cGMP) were prioritized.
- Proanthocyanidins (PAC) content. Studies show these comounds to be responsible for the potential effects of cranberry products on urinary health, making PACs an important component of cranberry supplements.
- Production method. Using organic over non-organic sources of cranberries can limit exposure to pesticides and synthetic fertilizers.
- Additional ingredients. Products containing additional components can provide additional benefits at the risk of an increased number of side effects.
Best cranberry supplement: an overview
Cranberries are bright-red berries that provide a tart treat packed with antioxidants. However, for many, cranberries are too tart or require sugar to make them more palatable. To experience the health benefits of the fruit, many turn to tablets or capsules containing dried, powdered cranberries that provide similar health benefits as the fresh variety.
With many different brands and formulations on the market, it can be difficult to select a high-quality product without having to pay a fortune. To aid in selection, we have provided our list of the top five cranberry supplements.

Why use cranberry supplements?
While there are conflicting opinions on the health benefits of cranberries, there have been some encouraging studies linking cranberries to certain well-being improvements.
May boost urinary tract health
Cranberry consumption for urinary tract infections (UTI) is one of the most commonly suggested health benefits. While there are conflicting opinions on the effectiveness of the fruit, a meta-analysis has shown cranberries may be useful in lowering the occurrence of UTIs.
It is important to understand that cranberries do not treat infections. However, the proanthocyanidin contained within the cranberries may help reduce the attachment of bacteria to the urinary tract, potentially resulting in fewer urinary tract infections. To determine if cranberries are right for you, please discuss them with your healthcare provider.
May protect against oxidative stress
Chronic exposure to oxidative stress in the body is attributed to premature aging and the occurrence of chronic diseases. Ingesting powerful antioxidants may help boost the body's natural defenses against oxidative stress.
Cranberries are known to contain high levels of antioxidants that ideally should maintain their effectiveness during the manufacturing process into supplements.
Interestingly, dried, powdered cranberry extract used in supplements has been shown to contain higher levels of antioxidants than jellied and sauced cranberries. In small clinical trials, cranberry supplements have demonstrated the ability to potentially reduce oxidative stresses within the body.
May have benefits on cholesterol
Cranberry supplementation has been shown to potentially have beneficial effects on cholesterol levels, in particular high-density lipoproteins (HDL). However, there is a limit to the benefits of cranberry supplements in increasing these levels and studies have been conflicting. Therefore, further research is needed to confirm the relationship between cranberry supplements and HDL levels.
If you are considering adding a cranberry supplement to your overall diet for the purposes of heart health, it is recommended that you talk to your healthcare provider to determine if it is safe, especially if you're taking any medications.
May reduce blood glucose levels
Studies have evaluated the use of cranberry supplements for the purpose of reducing blood sugar levels in patients with Type II diabetes. In a small study involving 58 male patients, a glass of cranberry juice every day for 12 weeks was shown to have a positive impact on blood glucose levels in these patients.
Additional studies still need to be conducted to see if this effect can be transferred to cranberry supplements or if the effects are specific to the intake of the juice.
Suppose you are currently taking medications to treat diabetes - in that case, it is important to have a discussion with your healthcare provider before using cranberry supplements or juice to ensure your blood sugar levels do not drop too low.
Types of cranberry supplements
For many, cranberries' taste profile is off-putting, making it difficult to add them to the diet. Therefore, patients have turned to supplements to help increase their cranberry intake and obtain health benefits. Here, we discuss the options for cranberry supplementation and the benefits and disadvantages of each type.
- Capsules and tablets are available for those who prefer pre-measured dosages that are convenient to take on the go. However, these may not be a good option for those with difficulty swallowing pills.
- Gummies provide many of the benefits of capsules in terms of pre-measured dosages and convenience, with the added benefit of being better for those with difficulty swallowing pills. However, the flavor of the gummies may be a disadvantage for some.
- Liquid extract is another option available for those with difficulty swallowing pills, but the flavor profile of these extracts may not be palatable and require dexterity for proper dosing.
Key ingredients to look for in cranberry supplements
Urinary health benefits seem to be due to the dose of proanthocyanidins, especially type A, contained within the supplement. This compound is thought to inhibit bacterial binding within the urinary tract, allowing the body to flush them out during urination. Many supplements will standardize the dose based on proanthocyanidin content.
It is recommended one obtain at least 36 milligrams per serving. However, some researchers state that the optimal dose is still in discussion.
Many other compounds are present in cranberries that provide antioxidant properties. These compounds include phenolic acids, anthocyanins, flavones, flavonoids, and organic acids. The content of phenolic compounds depends on agricultural practices, geographic locations, and harvest time. Thus manufacturers need to obtain quality cranberries from trusted sources.
How to use cranberry supplements effectively
The effectiveness of cranberry supplements depends on the consistency in which the supplements are used. Therefore, selecting an easy-to-remember time that can be incorporated into your routine is best for boosting the effectiveness of cranberry supplements.
Cranberry supplements can be taken along with a meal or on an empty stomach with a full glass of water.
Is it ok to take cranberry pills every day? Long-term studies have not been conducted to determine the safety of daily usage for longer than 6 months. Taking cranberry supplements using dosages of 250 to 1350 mg daily for up to six months is generally considered safe.
Possible side effects and considerations of cranberry supplements
Main side effects include diarrhea and upset stomach, especially with high doses. Rarely, some people may experience severe allergic reactions to cranberries.
Because UTIs are common during pregnancy, women often ask, can you take cranberry pills while pregnant? While a Norwegian study showed no increased risk of adverse effects during pregnancy, it is advised to talk to your doctor before using cranberry supplements, as there is still no general consensus on whether it is safe to take them during pregnancy or when breastfeeding.
Patients with a history of kidney stones should avoid cranberry supplements - even though the evidence is inconsistent, it's better to stay on the safe side. In addition, cranberry supplements may potentially interact with blood thinners such as warfarin and should be discussed with your doctor before starting.
Best cranberry supplement – conclusion
Cranberries are known to provide a powerful antioxidant punch, but many do not find their tartness palatable, at least on a daily basis.
When selecting a cranberry supplement, confirm the dosage of proanthocyanidins provided per serving. This compound may help boost urinary health when taken at 36 mg daily.
While cranberry supplement benefits still require additional studies to confirm their health benefits, these supplements may be worth trying if deemed safe by your healthcare provider.

FAQ
Can I take cranberry supplements every day?
Yes. Many clinical trials have shown the safety of cranberry supplements when used daily for up to 6 months. Long-term studies are lacking to ensure the safety of these supplements for longer periods. Therefore, if you plan on taking them longer, please contact your healthcare provider.
Can cranberry supplements replace antibiotics for UTI treatment?
No. Cranberry supplements are not effective in treating UTI infections. These require antibiotics to effectively treat. However, cranberry supplements have been shown to be helpful for people with recurrent UTIs, as they may make the attachment of bacteria to the urinary tract more difficult. Thus if the bacteria have already established themselves as in an infection, cranberries would not be effective.
How long does it take for cranberry supplements to work?
Cranberry supplements do not produce immediate effects and require consistent use to be effective. Typically it may take two months or more to observe the benefits of cranberry supplements. For this reason, it is recommended to trial a cranberry supplement for a minimum of eight weeks before determining it to be ineffective.
Are there any dietary restrictions when taking cranberry supplements?
There are no specific dietary restrictions that need to be followed when taking a cranberry supplement. However, patients with diabetes should be mindful of the sugar content within certain supplements. Patients with a history of kidney stones should consider avoiding cranberry supplements as cranberries are high in oxalate.
