Done wonders

Heard about Earth Fed Muscle from a youtube that my husband watches pretty much daily and thought I would give it a try. My daughter mentioned to me about trying collagen. So far, am very glad I have given it a try. My digestive system has definitely improved, which makes me feel that much better. Been using it for 5 months now. Only product I have found thus far that I can truly say has made a difference.

It's a whole experience

I'm not quite sure if I'm seeing any effects from using collagen yet but easily mixes with my coffee in the morning without leaving an aftertaste. EFM's customer service is honestly part of what keeps me purchasing from them. If I'm going to buy some sort of protein supplement, I might as well support a local, small company that actually gives a **** about their customers and takes a political and moral stand.

Still Don't Have It

I just checked Fedex and although it shipped on the 18th, I won't have it until 10/6! Can't recommend something I never got...

Sneaky way to add in more protein

This product is great for mixing in to practically anything. Bonus benefits!

More protein!

We mix this with our daily greens regimen. Can’t taste it at all. Mixes great and adds that extra protein we want!

Gold Medal Collagen

Always a pleasure ordering from EFM. Their products are top of the line, this is by far the best collagen we've used. We enjoy ours mixed with a scoop of their whey protein

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.

I have this now everyday in my morning coffee and after about 2 weeks, I'm feeling great as I increase my workout regimen.

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
