Good stuff

I originally bought this to add protein to my day, but I like the added benefits of the collagen. I need all the help I can get to keep up with my grandkids!

Great for Keto Diet

Becoming a recent Type 2 Diabetic, I needed to reduce carbohydrates but maintain my protein intake. I add this to my AM coffee and use before bed in camomile tea. Easily dissolves and no change in flavor of the beverages.

Good Protein Source for a Senior Citizen

As a senior, I stay well hydrated and active, needing a quality protein source I can easily take frequently to maintain muscle. Earth Fed Muscle is a top choice for me. Easily dissolves in my morning coffee to start my day. No taste to mask my coffee flavor. And excellent service.

Quality like all the EFM products

I have used many other brands Collagen but hands down this is the best mixing Collagen I have ever used. Completely tasteless in my morning coffee.

Collagen Protein

This product is amazing. It is packed with grass fed beef collagen protein instead of mysterious ingredients that other supplement companies use. I use this daily to supplement my joints - great product!
