Nutrilite Products - the Result of Extensive Analysis and Research
Every NUTRILITE™ product is the direct result of extensive field testing and laboratory
analysis, conducted by scientists, microbiologists, chemists, pharmacists, nutritionists,
and other technicians. We have made a significant investment in scientific expertise and
equipment, not often found in the nutritional supplement industry.
Our comprehensive analytical services include:
Bioassays – to identify beneficial ingredients and compounds
for our products.
Microbiology – to set specifications and test ingredients to
ensure product safety.
Analytical chemistry – to identify sources of ingredients,
and develop processes for creating safe, consistent, and effective products.
Nutrilite analytical chemists rely on highly sophisticated equipment and methods to support their work:
Gas chromatography/mass spectrometry is used to screen raw
materials and test finished products – especially to identify volatile components in essential
oils, or to test for those preservatives and other ingredients not allowed in some countries.
High performance liquid chromatography (HPLC) separates the
active compounds in a concentrate or finished product from other components. This lets the
scientist identify them individually and accurately determine their levels. HPLC supports
label claims and shelf life determination.
Nutrilite Bioassays: Identifying Beneficial Ingredients
In the bioassay laboratory, our scientists use cutting-edge research and equipment to help
product developers identify the most effective ingredients for NUTRILITE products.
Every day, we run assays – or tests – to predict the effect of a particular ingredient
on the human body. In 2005 alone, over 2000 assays were done, ranging from the effects
of a particular antioxidant to synergistic studies involving specific combinations of
potential ingredients for our products.
Bioassays measure the initial effects of an ingredient at the cellular, sub-cellular,
and genetic level, using living cells. Later, clinical tests on human subjects will
further our knowledge of an ingredient's effect.
Many of these tests involve the use of a sophisticated, robotic system allowing a
scientist to program a test, set it up, and move on to other tasks, while the system
performs the test and delivers the finished data directly to the scientist's desktop
Nutrilite Microbiology: Ensuring Product Safety
Microbiology is the science and study of microorganisms, including algae, fungi,
bacteria, and viruses.
Our microbiologists work every day to set specifications and test ingredients
before the actual formulation of NUTRILITE products.
In addition, they determine safe levels of fungi such as bacteria, yeast, and
mold – natural microorganisms inherent in the many farmed ingredients used in
After the products are formulated,
Nutrilite Quality Assurance
ensures that these specifications are met in the finished product.
Nutrilite Analytical Chemistry: Analyzing Raw Materials and Finished Products
The job of analytical chemistry is to characterize and subsequently
analyze the raw materials that go into NUTRILITE products.
When the right form and strength of the raw material is
determined, methods for using those compounds are formally validated.
The analyzed raw materials are used in finished products.
Methods are then developed and validated to ensure that the
active levels specifications and claims for the finished products are met.
These methods are then used to verify the shelf life of the
product, ensure packaging integrity, and guarantee consistent performance of the finished
Innovative research keeps NUTRILITE products at the
forefront of nutrition science.
