[This review was collected as part of a promotion.] So I received this a week or so ago, and have been using it daily ever since! I am definitely starting to notice a difference, in the little things. My hair is starting to look healthier, my nails, my skin. Its all starting to look great! im pretty pleased with the overall quality, and taste of this product! I will purchase after I am done with the sample, and continuing using!

[This review was collected as part of a promotion.] This is my first time trying a Youtheory product and I am pretty pleased. The only reason I deducted a star is because the container is only a little over half full, I expected it to be filled to the top being brand new. I can see running out pretty quick. I use the powder every morning in my coffee. The powder is vanilla flavor so it goes well with my French vanilla creamer. I found you have to mix it really fast or else the powder starts to harden and get chewy. I haven't tried mixing it in anything cold yet. So far I am pleased and I will be looking to purchase more products from Youtheory.

[This review was collected as part of a promotion.] I was so excited to try this collagen powder! I am 34 and have recently started loosing a lot of hair. I was very worried about my hair lose and was looking for something to help me and my hair! I have used this product for about a month and have already noticed a difference in a lot of things! I have a lot of new growth coming in! My hair appears to be shinier and don't seem to break off as bad as is did! My hair has grow in length. I have also noticed my nail are growing and are stronger. I have always had brittle nails that were very thin and would tare and break off! The powder is a vanilla flavor! The best way to drink it that I have found is in my coffee! It don't taste bad but it's not wonderful. I think I would rather take the pills! My skin even looks healthier!

[This review was collected as part of a promotion.] This product is tasty and easy to use. It has made a huge difference in my knee pain. I work on my feet, and have all my life; my knees are shot. I mix this with my coffee and can get through a day at work, and am noticeably more comfortable when I get home.

[This review was collected as part of a promotion.] Very easy to use. Very digestible. I was highly satisfied and it was a trusted brand. I would highly recommend this product to anyone. It has many benefits that are wonderful for many people. I would purchase.

[This review was collected as part of a promotion.] I love the benefits of this collagen powder but I wasn't the biggest fan of its vanilla flavor. I have never been a huge fan of vanilla but gave this a shot anyways. I add it to my smoothies and that is quite delightful!

[This review was collected as part of a promotion.] The vanilla flavor tasted okay. I liked the resealable container because it made it easy to store, but it was kind hard to get the powder out of the small opening. Overall I enjoyed it and would recommend it!

[This review was collected as part of a promotion.] I am so very excited that I was able to try YouTheory Collagen Powder with Biotin and Vit. C. I got the vanilla and have to say I was very pleasantly surprised. I am normally not a fan of powders because of their tendency to clump, the gritty texture and a lot of times the artificial taste they give off. This collagen powder, however, had none of that. I have never taken a collagen supplement so I was unsure what to expect from this. The directions say to add a rounded scoop to 6-8oz. of water, coffee or juice. I chose to first add it to my morning coffee. It dissolved completely and left no gritty texture or aftertaste. It made for a welcome addition to my coffee. I have since added it to smoothies as well with great success. I have had no negative side effects from taking this supplement. I have, however, noticed that my hair feels softer, and my nails, which would break with the slightest touch, are crazy strong! They are growing like crazy as well. I also have noticed that I don't have as much leg pain as I usually do. I have fibromyalgia, and degenerative discs in my back that both cause a lot of pain, especially in my legs. I don't know if it's the supplement powder or what, but I have noticed a slight decrease in pain since starting this and I'm hoping that with continued use I can get better results!

[This review was collected as part of a promotion.] This collagen powder works really well and it's pretty awesome. I use it in my smoothies for lunch everyday. Since I started using it, for a week and a half now, I have noticed that my hair has stopped falling out as much as it was, my nails look like they have been growing faster and have stopped breaking so easily, I feel like my skin feels and looks nicer and softer. I like the size of the bottle as well. I will continue to use this collagen powder.

[This review was collected as part of a promotion.] I have been using the Youtheory Collagen Powder for about a month. I put a scoop in my coffee every morning (makes it easy and routine). I really do see a difference in my skin, it feels better and tighter, and I feel more comfortable with less make up, definitely a win!
