Does the coloration of Viviscal tablets vary?

[QueenT]

I recently recieved my third box of Viviscal tablets. The new box of tablets contained tablets that were slightly lighter in color than the first two boxes.

Has anyone else had this experience?

I started taking viviscal before I knew I was pregnant, I bought 6 boxes from 2 different vendors some had a 2008 expiry, I found these to be lighter in colour to my other batch with a 2010 expiry. I am not sure why this is. I have not taken them yet cos I discovered I was pregnant soon after buying them and I decided to hold onto them till I have finished nursing.
