I have been using this for approximately 2 weeks and have noticed an improvement in my facial skin. Granted I also take hyaluronic acid and alpha lipoic acid. Still I took those before and didn't notice a difference like I do now. Lots of people are comparing this product to Neocell (which is a very good product) but I think both products are comparable but Doctor's Best is a little less expensive (even thought Neocell is a very good price too). I would highly recommend this product especially for its anti-aging benefits throughout the body (but you will notice it on your face first).

I just switched over to this from the other brand that's the same thing. This one dissolves in water easier. My shoulder doesn't make that joint rubbing sound anymore and my husband says his knee is doing a lot better [isn't hurting anymore]since he's been taking Collegen Types 1&3,.

Erased fine lines...

After about 2 weeks of taking this once a day, the fine lines around my eyes are literally gone! (I'm 33 and have noticed them for the past 6 years. No other supplement or cream had worked.) I'm doubling the dose now hoping it will effect the lines in my brow. My knee pain also seems to be improved. Great stuff, highly recommending it to everyone I know!

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.

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.
