I have used the product for approximately 3 months. I can't see any difference in my hair but I think my skin appears better so assume it is doing something with my hair. My issue with this product is the packaging. I received 4 boxes of which two showed leakage. The tops were intact but the leakage seems to come from the sides which also seem intact. I wrote the company and they suggested a cool/dry place to store them. It does not consistently work. Sam's replaced 2 of the boxes. Two months later, I see another one of the four boxes leaking with two empty tubes.

so happy sams have this product this is first time i buy i like it

easy to use, and great results!

Easy to open and drink. I like the flavor and just drink it straight.

This product is not of good quality. DO NOT order this. It tastes horrible, mixes horribly, and really tastes like it is bad poison.

Tried for the first time and have been using about two weeks. I like this product. Taste could be better...a little bit like tasting a vitamin. Not sure why the packaging can't be easier to squeeze out.

I've been taking this product for 3 months now and have seen a difference in my hair and nails. It used to be very dark/thick and now it is a lighter/watery consistency. They have changed something in the formulation. Very Disappointing.

I checked the ingredients and it has sucralose, which has been shown to be harmful, and maltodextrin, which raises blood sugar and insulin. I don't know what these sweeteners are doing in a supposed health supplement.

Have a good flavor taste like Raspberry ice tea

Love this Collagen!! It works great my nails and hair grow like a weed. Very pleased!
