Jamieson guarantees the purity, potency and safety of each product until the expiry date listed on the label. Jamieson's 360 Quality Promise represents our commitment to a full-circle process that ensures our natural-health supplements are the safest, purest and most effective on the market. 360 Quality begins with our comprehensive raw material selection process ensuring that only the purest ingredients from the world’s finest resources are used in each formulation. It carries through to our meticulously controlled production environments, extensive clinical testing, and a minimum of 360 quality control steps along the way to ensure absolute integrity and reliability. In an age when nutritionally enhanced products of questionable provenance crowd the marketplace, our 360 Quality Promise distinguishes Jamieson from other manufacturers — and is a symbol of safe, clinically pure and potent formulations that you can trust.
