What Do We Mean by “Gluten Free”?

By gluten free we mean that the product is free of gluten proteins from the following grains: wheat, rye, barley, oats including triticale, kamut, spelt as well as any modified gluten protein from those grains AND the gluten levels of the finished product is below 20 ppm.

What Do We Mean by "Non-GMO”?

When we refer to “GMO” (otherwise known as “genetically modified organism”), we mean an organism that was modified through genetic engineering, or other scientific means, that alters its natural state to one that could not have occurred naturally.

Centrum Non-GMO Standard

It is important to note, there is currently no official Canadian non-GMO definition. We’ve based our non-GMO standard on a careful evaluation of Health Canada guidance documents, existing and proposed standards from within and outside Canada and standards set by independent organizations.

Our non-GMO standard requires sourcing non-GMO by origin ingredients for our verified products. This means we use an original seed source that is conventionally grown (not genetically engineered) for our ingredients. Our verification is based upon a thorough evaluation of supplier documentation confirming the non-GMO status of the ingredients that make up our products.

Non-GMO by IP refers to non-GMO by Identity Preservation. This requires practices and processes for controlling contamination from at-risk GMO inputs and ingredients. While non-GMO by IP is acceptable for our standards, it is not required. PCR (Polymerase Chain Reaction) testing is a method of detecting genetic material in products. A PCR(-) finding alone is not sufficient to ensure that a product is non-GMO. In certain cases, testing may be used as a verification tool.

We allow for the use of fermented ingredients or processing aids that are genetically engineered, as long as the genetic material from the processing aid is removed from the finished ingredient and is not present in the final product. For example, some B Vitamins (riboflavin and vitamin B12) are produced using a fermentation process that employs a genetically-engineered processing aid. In the PCH non-GMO standard an ingredient manufactured using the genetically-engineered processing aid, such as riboflavin and B12, would not be considered genetically-modified as long as the nutrient medium is conventional (not genetically engineered) and the genetically-engineered processing aid is purified out such that residual GE DNA is present at <0.9% in the ingredient.

Processing Aids

In Canada, there is no regulatory definition for processing aids. However, the Food Directorate of Health Canada has defined a processing aid as a substance that:

  • is used for a technical effect in food processing or manufacture;
  • when used, does not affect the intrinsic characteristics of the food; and
  • when used, results in no or negligible residues of the substance or its by-products in or on the finished food.
