Utiva Cranberry PACs is our main flagship product which is a unique cranberry extract providing 36mg of proanthocyanidins or PACs (the active molecule from the cranberry). We launched this product as it is recognized in Urology and physician guidelines as the necessary amount of the active molecule from cranberries to effective help prevent bacteria from sticking and causing infections. 1 Utiva capsules is equivalent to about 9 regular cranberry capsules (to get 36mg PAC). Over 20,000 customers use this including women, and men, to reduce their dependence on antibiotics. Size: 30 & 90 capsule options. Recommended Dose: Maintenance: Take 1 capsule daily around the same time with or without food. Sex-Associated or symptomatic: Take 2 Utiva capsules the day of and 2 more 24 hours later. BONUS: Utiva Cranberry PACs has removed the Vitamin K and has trace amounts of Oxalates. Most cranberry products do not claim this and may therefore impact blood thinners and kidney stones.
