Where do raw materials come from?
Due to company policy, we cannot disclose the names or locations of raw material suppliers. However, USANA scientists conduct numerous tests on both raw materials and finished products to ensure purity and safety.
Among other testing, we use HPLC, ICP-MS, FTIR and GLC for quality control purposes. We perform multiple testing and screening procedures to assure that our raw materials are not only pure, but also that they contain no unintentional compounds (pesticides, heavy metals, organic contaminants, manufacturing contaminants, etc).
Such testing is important because the raw ingredients that go into USANA products come from a variety of sources. Some are derived from plants. Our vitamin E, for example, is the natural form derived from soy. Other ingredients, such as vitamin B12 and CoQ10, are produced microbiologically in fermentation, then purified. Still other ingredients, such as chromium picolinate, are produced synthetically. Chromium is purified from a mined mineral and then chemically reacted to produce the picolinate form. Folic acid in supplements is nearly always synthetic because it is preferentially absorbed and utilized over natural food folates, which must go through several conversion processes to be utilized as folic acid.
But again, regardless of their source, all raw ingredients that go into USANA products are selected for effectiveness, purity, and safety. We use vitamin and mineral compounds in the chemical forms, whether “natural” or “synthetic”, that are best absorbed and utilized by the body, and we purchase the materials with the highest standards for quality.
