Ask the Scientists: Your USANA Questions Answered

USANA Ask the ScientistsThe last time we posted about Ask the Scientists, we received a lot of great feedback from our audience. Readers were either happy to discover this nifty tool or quick to mention how much it’s helped them in the past. So we figured, why not feature Ask the Scientists on a regular basis?

As a reminder, Ask the Scientists is an awesome database of science- and product-related questions and answers located on under “The USANA Difference” and then the “Science” tab (right here).

Have you ever wondered about the specific ingredients of a particular product or how USANA formulates that product? Look no further than Ask the Scientists, where you can most likely find an answer to your question.

If you don’t have a particular question in mind, browse the database to build your knowledge about USANA’s products — it’s one of the quickest ways to impress potential customers.

Let’s take a look at a small sampling of questions found in Ask the Scientists.

How Do the USANA® Digestive Enzyme Ingredients Work?

Raw food does not generally exist in a form that the body can use as nourishment. Food and drink must be broken down in order to be absorbed and carried to cells throughout the body.

Digestive enzymes work alongside mastication (chewing), peristalsis (muscle contractions), stomach acid, bile, and other gastrointestinal components to help reduce food to smaller, more absorbable forms.
Each enzyme in the USANA Digestive Enzyme product is capable of breaking down a specific food component.

  • Amylase: breaks down starch
  • Bromelain: breaks down protein
  • Cellulase: breaks down cellulose
  • Lactase: breaks down lactose
  • Lipase: breaks down fat
  • Papain: breaks down protein
  • Protease: breaks down protein

Can USANA Make Product Recommendations for My Medical Condition(s)?

Current scientific evidence shows that a healthy lifestyle, including sound dietary choices, regular exercise, and nutritional supplementation where appropriate and advisable, plays an important role in reducing the risks associated with the development of certain chronic degenerative diseases.

USANA does not promote its products for use in diagnosing, treating, curing or mitigating any disease, nor can we answer questions concerning medications or other treatments and a potential for interactions with the USANA products.

We strongly encourage individuals to seek the guidance of a licensed physician, pharmacist, or other health care professional in making decisions regarding nutritional supplementation. These health care professionals have the training and expertise necessary to help concerned

We further recommend that as a basis for such discussions, individuals provide copies of labels describing the contents of the USANA products in question. This will better enable health care providers to determine which USANA products may be appropriate.

Can I Take Procosa® if I am Allergic to Shellfish?

The glucosamine used in Procosa is a highly refined vegetarian form of glucosamine. It does not contain chitin sourced from shellfish.

Where Do USANA’s Raw Materials Come From?

Due to company policy, we cannot disclose the names or locations of our 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.

    @ Micheal O’Shea USANA does not use GMO soy and has rigorous methods to test for that. I got an extremely lengthy email advising me to the hows of the process. Dr. Wentz would never allow such a thing. The response from distributor services. (It would be good if USANA put that on the label to quell doubts and fears.)
    “USANA does not use genetically modified organisms (GMO) in its product line. USANA is committed to providing superior quality without compromise and this commitment includes sourcing materials known to be free of any genetic modification.

    USANA has voluntarily adhered to recognized methods to ensure its products are free of genetically modified materials, and USANA is currently in the process of adding additional, more stringent measures to guarantee its products continue to be free of genetically modified material.

    Producing commercial non-GMO seeds, grains, and food products requires preserving the non–GMO identity of such products through every stage of production. As a result, systems of identity preservation (IP) have become increasingly important. IP is a process of maintaining the segregation and documenting the identity of an agricultural product. USANA has chosen to use identity-preserved materials in its product line, including soy protein, so we can guarantee it is GMO-free.

    USANA is also required by government health authorities to provide certification of non-GMO for all products produced at our FDA-registered facility, and to preserve and maintain the identity of each raw material that we source. Additionally, with USANA now operating in the European Union, our products are held accountable to the strictest GMO laws in the world.

    USANA customers can enjoy our products with confidence, knowing we are 100 percent committed to improving human health. That commitment includes sourcing materials known to be free of any genetic modification.”

      Richard Miller says:

      Why has Usana not replied to my GMO concerns in their essential vitamins and minerals , pretty simple question , is it because you don’t want to admit to using Gmo soy lecithin or GMO dextrose both of which are commercially available by avoiding answering my concerns it leeds me to believe your hiding behind the truth that Usana essentials contain Genetically modified organisms, I’m stopping taking them now because of the lack of transparency from usana .
