"After using thus for two weeks it caused sever dirreah and nausia! I am very much into health and in healthy foods and supplements, and I get most of my best supplements are good foods. I decided to add collagen to my diet and I have never been so sick in my life. The sad thing is is I can’t return this after paying such a fortune for it and I’m glad I didn’t do a subscription, I would be careful because maybe it’s just me, but I’ve taken collagen before and never had a problem but this collagen has made me very very ill and it almost completely dehydrated me and I don’t know why it would do that, but I was in the bathroom every time I took it within an hour and all day long until I could not take the stuff anymore and it has made me very very sick . I don’t know what else I can say is there was something wrong with my supply or what but it’s not fair and I should be refunded for a product that makes me this ill. My doctor said to stop taking it immediately and do not take another bit because he didn’t know if it was a bad batch or that there’s something wrong with this collagen this is supposed to be one of the top notch companies and I don’t know why it would make me sick like this but I stopped after two weeks and then tried after a few days to take one more dose, and it did the same thing again and that I knew for sure that’s where it was coming from because I am very exact with my diet and my health regiment . I am mature person and I jog 5 miles a day and do strength training and an M and an excellent health and look 45 years old and have the heart of a 25-year-old and this stuff made me so nauseous and sick and died full of diarrhea that I couldn’t function for days . I don’t think it’s fair that I don’t get a refund for a product that made me this sick and Cosmi health problems and I’m thinking about contacting an attorney."

"It's hard to gauge the effectiveness of supplements, but I can say I Do see a difference in my hair. Less thinning and shedding. That was my primary goal, and it was reached. So I'm definitely pleased. It's easy to use also. I make protein shakes daily and I just put a scoop or two into my shake and it's done. Zero change in taste of my shake so it's like it's not even there. Will definitely use this regularly as if it's helping my hair so much, I'm sure it's also helping my skin and other things. AAA+++"

"I love the quality of this powder and its properties. I have purchased it for my mother and mother-in-law due to its incredible results with me. Although it doesn't have a taste when taken on its own, I made the mistake of mixing it with my glass of chocolate milk. As a tip: don't do it. Besides that flavor change with certain liquids, I find it amazing that it provides 10 grams of protein per serving."
