TheraCran One cranberry capsules contain 36 mg of proanthocyanidins (PACs) per capsule. These gluten-free capsules contain a high-potency cranberry extract that supports urinary tract health.

Just one capsule of TheraCran One per day helps keep urinary tract infections (UTIs) at bay.* The proof is in the proanthocyanidins – or PACs for short. Research suggests that a daily dose of 500 mg of cranberry powder with at least 36 mg soluble cranberry PACs may reduce the risk of recurrent UTIs.


What are proanthocyanidins?

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.*

How is TheraCran One different from drinking cranberry juice?

TheraCran One is virtually calorie- and sugar-free. In comparison, 10 ounces of cranberry juice cocktail has approximately 175 calories and 37 grams of sugar, more than a can of Coke®. People with diabetes can safely take TheraCran One since it is sugar-free and will not affect their blood sugar levels as juice will.

TheraCran One is less expensive than juice. One cranberry capsule per day of TheraCran One costs about 20% less than the equivalent amount of cranberry juice.

TheraCran One does not become less potent over time. Dried cranberry extract is stable, but cranberry juice can become less potent the longer it sits on a shelf.natural

Can I take TheraCran One cranberry supplement if I am pregnant?

Yes, TheraCran One can be taken during pregnancy. Studies have shown that cranberry supports urinary tract health in pregnant women.
