Q: I have heard nothing happens and it's just a marketing scam or that it may lose it's potency. Anyone really know what that date on the bottle is really for? Is it dangerous to take anything after the date on the bottle?
A: For the most part, it just loses it's effectiveness. If it is a couple of weeks or months past the expiration, then it is usually okay. If it is several months or a couple of years past the expiration, then you shouldn't take it. At that point the effectiveness is minimal and it might make you sick.
