Hi Carlee, congratulations on experimenting with collagen! It's one of those few supplements that most of us need and has few to none side-effects. 80% of the protein in the body is collagen, and we are simply not getting it in the modern diet.
Echoing some previous comments, I would check on supporting nutrients (nothing works in isolation). If skin quality is your goal, then fat-soluble vitamins, particularly vitamin A, which is best found in its usable form (retinol) in organ meats, egg yolks and dairy from pastured animals. Those foods will also provide other vital vitamins and minerals that support skin, bone and joint health. Good luck!
