Potency and Safety You Can Trust
Science is at the center of everything we do at USANA—and your health and safety are paramount. USANA follows strict standards to maintain the highest levels of manufacturing standards to produce the very best nutritional supplements.
Because USANA is an international company, we meet the manufacturing and regulatory standards of each of our markets. To achieve these high standards, we regulate every aspect of our manufacturing process, including our facility design and maintenance, supplier validation, production design, product testing, and more.
This includes:
- Raw material validation. All ingredients are reviewed and tested by our in-house quality assurance team for purity and quality.
- Testing at every level of production. From conception to bottling, USANA guarantees the safety and purity of every tablet. What’s on the label is what’s inside the bottle. This includes testing for temperature and humidity.
- USANA’s formulas are designed for maximum potency through a product’s shelf life. Each bottle is stamped with an expiration date. All food products have a best before date printed on the container.
When you trust your health to USANA, you know exactly what you’re getting. USANA’s potency guarantee promises that the USANA vitamin or supplement you’ve chosen has been held to a higher quality standard—just look for Dr. Wentz’ signature.
To receive the Potency Guarantee seal, each supplement must meet the highest standards in purity, identity, composition, strength, and quality. Because USANA voluntarily submits our products for third-party verification, you can consume our nutritional supplements with confidence.
