Final Thoughts

The product label will provide the most accurate ingredient information. You should reference the label at the store to verify a product does not contain dairy if you desire to avoid it.

Some products have the potential to contain trace amounts of dairy if they are made in a facility where cross-contamination is possible. The label or the product website will often indicate this information.

Of course, contact the manufacturer with questions regarding ingredients if anything is clear.
