They have filtered, spring and reverse osmosis. I would call about collagen.
I believe our Wellness department has a variety of collagen supplements that can be added to water and other drinks. Just in case, I know that Culligan is a water treatment company that makes various water machines. If you're inquiring about filtered water, we do have a water machine (though, I do not believe it to be Culligan brand) that offers reverse osmosis water as well as alkaline water. I hope this helps!
