In my last order from vitacost.com, I got 3 bottles (180 pills) of Jarrow Formulas PhosphOmega Krill Oil. This batch has a strong, unpleasant smell. I've taken a few doses without ill effects, but I wonder if the oil has gone rancid or is bad.

Jarrow Krill Oil is one of my usual supplements. I have not experienced odor problems in the past. I e-mailed vitacost.com customer service, but they have not responded.

Should I toss them out and re-order? Should I attempt to get vitacost to make good on the order? Is a strong smell maybe not a sign of anything?

Advice?
