BioPure DHA®’s unique purity and potency are controlled from source to shelf. Isolated waters, an exclusive fish supply, and proprietary cold-extraction technology create naturally pure, DHA-rich fish oil. Mild processing further maximizes purity to produce mild, deodorized oil, while preserving its natural triglyceride structure and high DHA content. In addition to these controls, BioPure DHA® meets or exceeds international standards and CRN recommendations by subjecting every single batch to third-party laboratory tests.
