Is Collagen Peptides Wheat Free?

I am a celiac, and I have been using this Vital Proteins brand supplement uneventfully for quite some time until I decided to give this limited edition Ice Pop a shot. Although it says made without gluten, my reaction says otherwise. I also subscribe to an APP that identifies products with gluten, and a warning sign popped up when I decided to challenge Vital Proteins’ claim. I will continue their original recipe, because it is a good collagen product.
