We do not recommend relying on lists or publications for gluten-free status as manufacturers can change the ingredients in a product at any time and a list may not be updated frequently enough to reflect these changes. The most efficient way to find out if a product is gluten-free is to read the ingredient label carefully. If it is not clear if the product is gluten-free we recommend to contact the manufacturer directly.

Ways of Finding Information & Product Research for Gluten-Free Status

Product labels

Calling the manufacturer (this is usually the quickest way)

  • The manufacturer’s phone number can usually be found on the product label or their website.
  • Ask the customer service representative for gluten-free status of their product.
  • Questions to ask if product is NOT labeled gluten-free (safety determined on an individual basis):
    • Does the product contain any wheat, barley or rye ingredients?
    • Is gluten used on the same belt/equipment?
    • Do you have a cleaning process between products
    • What are your procedures for preventing cross-contact?

The manufacturer website (often listed on the product)

  • Look for their “FAQ” section.
  • Use the search function to locate the product and information on their website.

Email the manufacturer

  • Email can be found on their product or their website.
  • Note that an answer may take a lot longer than calling.

About Oats:

Oats are a bit more complicated. One of the biggest issues with oats is that a lot of sources of oats have had cross-contact with gluten-containing grains – even some that are labeled gluten-free. Always discuss with your healthcare provider before introducing oats and always choose oats that are labeled gluten-free.
