TheraCran® One Cranberry Capsules (90-day supply)

Q. How is TheraCran One different than other cranberry supplements?

TheraCran One is the only cranberry supplement that has been independently tested and certified in the US for its purity and proanthocyanidin content. Most products are not standardized or tested for proanthocyanidins, and do not list proanthocyanidin content on their label.

TheraCran One contains 36 mg of proanthocyanidins per daily dose of one cranberry capsule. This is the dose of proanthocyanidins that has been shown in research studies to be beneficial for urinary tract health.*

TheraCran One contains a whole cranberry extract from cranberry juice, skins, flesh, and seeds, and each batch is tested for bioactivity. You can be sure that TheraCran One delivers the recommended amount of bioactive proanthocyanidins.

Q. What are proanthocyanidins (PACs)?

Proanthocyanidins (PACs) are compounds naturally occurring in cranberries. Researchers have shown that the particular type of proanthocyanidins found in cranberries is beneficial for urinary tract health.*

Q. Are there any side effects from taking TheraCran One?

No. There are no expected side effects from TheraCran One. Any person with a known allergy to cranberries should not take TheraCran One.

Q. How is TheraCran One different from drinking cranberry juice?

1. TheraCran One is just one capsule per day. To reap the same benefits as just one capsule of TheraCran One, you’d have to drink 8-10 ounces of cranberry juice cocktail every single day.
2. TheraCran One is virtually calorie- and sugar-free. In comparison, eight ounces of cranberry juice cocktail contains about 110 calories and 25 grams of sugar.
3. TheraCran One is more shelf stable. Many experts in the cranberry field suggest that the soluble PAC content of cranberry juice decreases the longer it sits on the shelf. But, TheraCran One contains a stable cranberry extract and effectively maintains its PAC content up to the expiration date shown on the bottle.

Q. Can TheraCran One be taken along with other nutritional supplements?

Yes. TheraCran One can be taken along with other nutritional supplements. There are no known nutritional supplement interactions with TheraCran One.

Q. Does TheraCran One interact with prescription medications?

No, TheraCran One will not interact with any prescription medications.

At one time it was thought cranberry would increase how long warfarin (Coumadin®), a blood thinner, is in the body, and increase the chances of bruising and bleeding. But recent studies have shown that there is no significant interaction.

If you take warfarin (Coumadin), however, it is important to continue to closely monitor your INR levels once you start taking TheraCran One.

As with any dietary supplement, it is recommended you discuss with your pharmacist and or healthcare team to clarify whether TheraCran One can be taken along with your medications.
