USANA formulas aren’t just backed by science. USANA also use only the best scientifically proven ingredients. Then, they follow stringent analytical and quality control procedures to produce the most exceptional products. What you read on a product label is what you’ll receive in the product, and each batch is verified for potency before it reaches you.

USANA's manufacturing facility complies with pharmaceutical-grade Good Manufacturing Practices (GMP). Several government agencies conduct inspections of USANA’s manufacturing facilities ‑ each requiring strict control of procedures and documentation ‑ so the highest‑quality manufacturing standards are maintained.

USANA's research & development team carries out many studies and partners with experts and institutions across the globe to develop their high-potency nutritional supplements. USANA scientists have collaborated with many first-class institutions including, Boston University of Medicine, The university of Sydney, Australian Catholic University and The University of Utah.
