Great addition to morning routine

I love this collagen in my morning tea, especially when my breakfast doesn't have as much protein as I'd like. It is completely tasteless and mixes easily- can't even tell it's there! Definitely don't feel the need to snack as much throughout the morning when I have this with my breakfast!

Good with hot liquids

Great product in morning coffee. Doesn't really dissolve in cold liquids (or not nearly as easily as advertised, quickly clumps up and then requires very heavy mixing)

Reliable, quality product

I add Keystone Collagen to my morning coffee and post-workout protein shakes. There is no flavor and blends well with whatever you put it in. Highly recommend.

Collagen Works!

This has become a staple in my household. It makes us feel better and allows me to train harder. EFM Collagen is great quality and can be trusted - as a coach and athlete, this is important.

Keystone collagen

I’ve been using your Keystone Collagen and love the results! I discovered that there are many benefits to taking collagen. For a month I’ve been putting a scoop in my green tea in the morning (dissolves perfectly). At age 50 i started having mild joint stiffness, but not any more thanks to Keystone Collagen.

Collagen protein with ease!

I've had collagen protein bars and the like in the passed and they all tasted so horrible that I stayed away from collagen even though I know it is wonderful protein source. With the keystone collagen I just put a scoop or two in my coffee in my morning and I don't even taste it! I love it now and it helps me stay on my RP diet so much more easily

The best collagen ever

I LOVE this collagen. It mixes perfectly, doesn’t have that weird taste or smell like some other brands and it’s sourced in the US. AND the shipping was so quick! Yet another solid product from Earth Fed Muscle.
