Product Information

📋 Directions for Use

Because TheraCran provides a more concentrated dose of PACs, only two capsules per day are needed: one in the morning and one in the evening.

Suggested Use: Take one capsule, twice a day; one capsule in the morning and one capsule in the evening, with or without food.

🧪 Formulation Notes

Standardized to contain 36 mg of Cranberry PACs per capsule

TheraCran is a standardized, high-quality, high-potency cranberry supplement formulated to support and maintain normal urinary tract health.

TheraCran contains the amount of PACs found in 8–10 ounces of 27% cranberry juice cocktail, which has shown benefit in research studies.

TheraCran is the first cranberry supplement to use a new high-potency cranberry powder containing greater than 2.5% PACs.

TheraCran contains no cellulose or other agents that can bind to PACs, reducing their effectiveness.

TheraCran is the only cranberry supplement that you can be sure delivers the same amount of bioactive PACs as found in 8-10 ounces of cranberry juice cocktail.

TheraCran is virtually calorie- and sugar-free.

Why TheraCran?

How is TheraCran different? TheraCran is the first and only cranberry supplement that has been independently tested and certified for Proanthocyanidin (PAC) and other flavonoid content. PACs are the compounds that researchers have determined to be the active component of cranberries. For a cranberry supplement to be effective, it must provide an adequate dose of these PACs.

If the actual content of PACs in a cranberry supplement has not been measured and independently certified, the efficacy of that product is uncertain.

Many supplements on the market contain cranberry powder with only 1% PACs. As a result, it may take up to six capsules per day of these other supplements to get the recommended amount of active ingredients.

Many other cranberry products contain cellulose binders and may not be effective. TheraCran’s bioactivity has been tested in a clinical study at Rutgers University.

Why Theralogix?

Theralogix is committed to providing only the highest quality nutritional supplements. TheraCran is certified by NSF International, a not-for-profit organization that is the world leader in standards development and product certification for public health and safety. NSF has implemented the highest quality control standards in the supplements industry. The NSF mark is your assurance of a dietary supplement’s content accuracy, purity, and freedom from contaminants. Manufactured in an NSF-Registered Facility The facility where TheraCran and other Theralogix nutritional supplements are manufactured is registered with NSF and is in compliance with current Good Manufacturing Practices (cGMPs). These guidelines define the manufacturing processes, procedures, and documentation and assure the identity, strength, composition, and quality of the product. Medical Advisory Board Oversight The leading academic physicians and scientists of the Theralogix Medical Advisory Board meet regularly to oversee all product formulations. You can be sure that TheraCran is safe and reflects ongoing review of the most current scientific evidence. Visit www.theralogix.com to learn more.

TheraCran vs. Cranberry Juice? There are several reasons why TheraCran makes more sense than cranberry juice. TheraCran costs less than 60 cents a day. That’s 20–50 percent less expensive than the bioequivalent amount of cranberry juice.

In comparison, 10 ounces of cranberry juice cocktail contain 175 calories, more than a can of Coke. TheraCran doesn’t lose its bioactivity over time. Dried cranberry powder is very stable, but cranberry juice loses its bioactivity the longer it sits on a shelf.
