[This review was collected as part of a promotion.] I got this about a month ago and have added it to my coffee. It adds a nice vanilla taste to the coffee but is extremely clumpy. I had to keep using the spoon and pushbutton against the cup to get the clumps out. I have noticed that my skin is not as itchy and flaky as it was before trying this.

[This review was collected as part of a promotion.] I tried this for a couple of weeks with no noticeable difference. I also wasn't a fan of the taste. It could be that I'm young and didnt have much skin issues to begin with, so I'd be interested to see others' results.

[This review was collected as part of a promotion.] I really didn't see any kind of effects from this product. The flavor was nice aroma but didn't see what this product actually helped with. Maybe if I tried longer than a week I would of seen some sort of effects.

[This review was collected as part of a promotion.] I have weak nails, and I am also trying to take care of my hair and skin. I have been taking this collagen supplement for over a month already, and I am feeling the results! The most apparent difference I'm seeing ae my nails. They're less brittle and so much better looking than before. I will definitely continue taking this supplement!

[This review was collected as part of a promotion.] I was not a fan of the vanilla flavor as it tasted a little artificial to me, although I generally opt for flavorless. The powder dissolved well in hot liquid and I continued to see the same benefits from my typical collagen powder, so I would say this brand is effective.

[This review was collected as part of a promotion.] I got this product to see how well it worked compared to previous items I've used. It does exactly what it is supposed to do. The flavor was ok and it didn't have to gritty of a texture but not as smooth as I would like. All around a pretty good product.

[This review was collected as part of a promotion.] I received this as a sample and the vanilla taste is really good. It doesn't have that flavor that leaves your mouth dry so that makes me happy. I also really like how it it made me feel after using it for a few days

[This review was collected as part of a promotion.] I have been using the collagen powder and seen drastic change in my skin and hair. My skin looks tight and I have less hair fall. It has also helped in maintaining a good joint health. The powder form is more effective and I love the taste. The powder dissolved quickly and completely. There's no aftertaste. I look forward to purchasing more in future.

[This review was collected as part of a promotion.] Youtheory Collagen Powder with Biotin and Vitamin C, Natural Vanilla Flavor is a great product. We all want younger, healthier skin! I put it in my coffee and the vanilla taste combined with coffee is divine!!!

[This review was collected as part of a promotion.] I recently received the Youtheory Collagen Powder with Biotin and Vitamin C in the natural vanilla flavor. While this product wasn't a good fit for me,I will still and have still recommended it to my family and friends. It helps replenish the collagen and helps with anti-aging process in women. So if you are looking for something to help anti aging this is a good product to try. It's also awesome that it contains Vitamin C. We could all use more of that!
