Im writing about the liquid collagen

Im writing about the liquid collagen. I just read the in ingredients and I’m shocked to find out that it is made from pork skin - hydolyzed collagen ( porcine skin). That’s why it ma cause mild gastrointestinal distress?
Im quite disgusted because all the other collagens state what protein is in there and they don’t even identify this. I even bought two boxes and I’m really upset.

Really pleased

The Collagen does work.
I suffer from pimple recently at the age of 40.
My once smooth skin is now dry as sandpaper.
To my surprise this collagen has made an improvement in my skin.
Slowly it is getting smoother and I haven't had a single pimple.
I bought it from Costco.
Will definitely buy again.
It says take 6 tabs daily and tablets are quite large.
