Everything I use to make my organic. mold free collagen coffee. This is the collagen I swear by. I also add silica bc collagen gives your body the building blocks, but silica helps support collagen production and connective tissue… so they work really well together for skin, hair, and nails. And if you’re not using this collagen, make sure you’re always adding vitamin C when you take collagen because they work synergistically.This collagen I use already has vitamin C in it  LTKmorningroutine LTKOver40 LTKBeauty
