Good

I notice the difference on my hair in the first week of using the formula, but I do totally hate the smell and after taste, now dissolving in warm water and a cold water glass after make it better.

Doctor's Best Collagen

Good product at a good price. Has no tryptopan, which is god-- excess tyrypopan in the boad is not good, because it turns into "excess" serotonin, which is a factor in every mental/physical disease. Anti-serotonin medications, for example, are getting to be used , more and more, by doctors, for example. Ceffeine, aspirin, Niacinamide, and Vitamin A, all have anti-serotonin effects.

Prefer Neocell's

Purchased at iHerb

I bought this because the Neocell's one was OOS when I was ordering. The description is pretty much the same as Neocell's, so I'm assuming that they have the same supplier. The difference between the two is that this has added vitamin C, which makes it taste different. I usually drink it with carrot juice and I can detect the difference in taste of the juice when I use this whereas the Neocell's does not affect the taste of the juice. The added vitamin C does make it more convenient so that I won't have to take a separate supplement but I still prefer Neocell's.

After taking this for about 2month, my skin was improved amazingly. It feels much softer and better in general, and a fine line between my eye brows is disappearing. And joint pain in my knees is relieved a lot. It did not entirely disappear but the frequency of it is quite much reduced. Strongly recommended product.

Good for the joints, the skin and the hair. Makes nails grow quicker and stronger. Have used this for about 8 months. Makes hair grow faster too.
