Is Utiva Cranberry PAC safe for people who have a history of kidney stones?

Most cranberry products are known to have high levels of Oxalates which can aggravate kidney stones as the majority of kidney stones are formed when oxalate binds to calcium while urine is produced by the kidneys. Utiva Cranberry PACs is unique because it only has trace amounts of Oxalates due to our unique extraction process.  We also do third party testing of our formulation to verify oxalate levels. We do recommend checking with your doctor before starting any new supplement.
