I have no idea what collogen (sp?) is, and how it works. I thought that was what you had injected into your lips to make them look pouty. There are lots of weight loss pills that have it in them, and it's said to be 'safe' according to the radio!

i try it and it dosent work!

Collagen supplementation will do nothing for losing or gaining weight. Collagen is in basic terms what increases elasicity in your skin - your body produces less as you age so supplementation is a help for skin tone/texture as you grow older.
