Bonnie & Clyde is excellent. Personally, I would not use the Bayer one. It says "fish oil" in the ingredient, not sure what fish it comes from. I'm kind of anal about those things. Best oil should come from small oily fish, which B&C uses . They also have stellar reviews on amazon.
Get the smallest bottle & store in the fridge. It will last about 2 months. Since fish oil starts to oxidize as soon as it's opened.
