Great product

We especially like how easily this product dissolves in hot and/or cold liquids. This makes it very versatile to use anytime. No complaints here!

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.

Amazing

I was really pleased with this product. Mixes super well and it’s an easy add on to your protein shake. Will most definitely be purchasing the collagen again. Love me some EFM products �

So far, so good

To be honest I have only been using this product for a week which is not a enough time to really see or notice any changes. It does not taste bad so there is that. Mostly I am writing this to get the free shipping coupon, in case I want more.

Great Protein

I have enjoyed missing Link collagen protein. It is a very convenient easy way to get my protein in the morning. Dissolves quick in any liquid or juice you like to use. I quite often mix it into a hot tea and into my oatmeal in the morning

Missing Link Collagen Superprotein

I am absolutely loving this product!! I have a scoop in my coffee every morning and it works perfectly! I’ve tried other collagens that either clumped you the instant they contacted liquids, or had such a nasty smell that I didn’t want them near my precious coffee! Missing Link Collagen is smooth, dissolves completely, has zero taste, and works! I’ve noticed a significant change in my hair and nails and joints! Definitely give this a try!!

Awesome product, I love it!

Much easier to mix in hot or cold beverages than the gelatin. And as with all EFM products I love the simple and healthy ingredients.

Collagen

Mixes into any liquid well. Added it to a drink with my normal vanilla whey protein and didnt change the taste at all. I am getting ready to buy my next container right now.
