We are unable to address questions concerning comparisons with other companies’ products. We are obviously aware of the many competing products on the market. However, since we do not have access to the proprietary details of other companies’ products, it is difficult to make valid comparisons. You can make content comparisons yourself by reviewing product labels. Utilize the information in USANA’s official literature and website regarding quality of manufacturing and science-based formulations. Again, it is generally just not possible to make fair comparisons to competitors without access to information regarding their suppliers, proprietary formulas, and manufacturing practices.
