The CYSTELEH formula combines 1000 mg of D-Mannose, 300 mg of Cranberry extract (rich in proanthocyanidins, or PACs), and 1000 mg of L-Methionine. These ingredients have been studied for their role in limiting the adhesion of bacteria such as Escherichia coli to the urothelium, while L-Methionine helps regulate urine pH, creating suitable conditions in the urinary tract.

The CORE 8 complex contains 8 different bacterial strains along with inulin (a prebiotic dietary fibre) for daily nutritional support of the gut microbiome. In addition, vitamin C (80 mg) supports the normal function of the immune system and protects cells from oxidative stress.
