If your expiration date is good, then your pills are fine. a cracked tablet is just that-a cracked tablet. Still will do what ever it is supposed to do regardless. And of course Nioxin is going to say those cracked pills are ineffective....they want you to pay full price from THEM. Amazon pulled the bottles because of people complaining of cracked tablets. I plan to continue to take mine, as they have had no ill effect, and I have seen results. Ya'll can freak out if ya want to, LOL. Until the there is an official recall stating that these vitamins pose a health risk, I'm not gonna.
ETA, my bottles expire in late 2013...
