Cranberry extract is widely used in urinary-health supplements, with formulations typically standardized to proanthocyanidins (PACs) measured by the DMAC method.
For B2B buyers, the most important checkpoints are the PAC content, the botanical identity of the raw fruit, and whether the extract is free-flowing and stable in the finished dosage form.
Always request the analytical method used for PAC determination — comparing DMAC and other methods across suppliers can explain significant price differences.
