I guess you can overdose on anything! Koreans, Chinese and Japanese eat pickles of some sort every day. Maybe that's why they don't age like we do?
I love this stuff I eat it as least once or twice a week not counting using it as a condement on sandwiches. I alos love it on hotdogs, kielbasa, pastrami and corned beef sandwiches and I make alot of corned beef and pastrami because it's relatively inexpensive to make and last a good long time!
