This collagen does clump up a bit when you use it like other comments mentioned, but you just have to stir it a bit and it does dissolve eventually. It probably took me 45 seconds to 1 minute of stirring for it to completely dissolve. I use it in my coffee in the morning and it doesn't have any taste which I like.

The collagen is too clumpy! The scoop size is a lot for not disintegrating easily, therefore making it difficult to take the full serving size. I use it in my hot tea for reference. I will not repurchase this particular one.

It clumps up little bit compared to the other one but I still like it. I use only half of a scoop instead of full scoop because I felt that a full scoop was too much for my tea in the mornings
