Great price

I bought this at SAMs more expensive but I got more capsules, this bottle only contains 240. Both work equally well, so It just depends on how much I want to spend.

Better than Neocell Super C type 1 & 3

Posted by 5431718151715810834 on May 14, 2016

Having been taking 3 weeks, I found my skin is firmer & bounding! Yet both Dr Best and Neocell Super C collagen type 1 & 3 brought me the size effects of  stomach bloatedness (i alr added vit c to help for digestion) and lose appetite.   However,  I prefer Dr Best than Neocell, though DB's result may be slightly slower than Neocell,  yet still saw my skin better.  Neocell's, u may see the result within few days YET it made me very ill, fatigued n weak after taking 2 weeks -  I got serious headache, fat face, hard to  breath,..etc.. (u may see my review on Neocell) until I was very scared,  I stopped it at once and threw away 2 bottles of Neocell (another bottle for my sis)   I am not against Neocell's!  why I tried Neocell first becos I read many good reviews abt this brand,  however, it didn't work on me and caused me to fear, I believe it's the "sulfite" in their collagen that's caused me all these scary side effects!  Now I m still on Dr Best, I only felt stomach upset n lose appetite,  but as long aa it is disgusted (aft 30-45mins),   my stomach will be back to normal.  As for skin, yes, saw improvement. I will update more aft finished one bottle. However, I may go back to Japanese fish collagen which gave me no side effects.  You may surprise the most obvious result that i saw n experienced my skin improvement is not collagen but Phytoceramides. (u may see my review on this).

Nails are definitely growing faster and seem less brittle since taking this. Still hoping it will help my hair grow faster :D Too early to tell, I think, three weeks so far...
