LOUISVILLE, KY (WAVE)- As many people do, Dawn Keegan Silverstein takes fish oil capsules every day.
"Fish oil supplements are omega 3s and those are important for your heart health" Dawn said.
Consumer Reports tested 15 top selling brands sold in the U.S.
"All did have the amount of omega 3 fatty acids promised on the label.. And the levels of dioxin-like PCBs and other contaminants were below the limits set by the us pharmacopoeia" Dr. John Santa said.
But with four brands, at least one sample had total PCB levels in amounts that could require warning labels under a strict California law. And with Kirkland Signatures enteric-coated capsules, the coating didn't disintegrate properly, and that can give a fishy aftertaste.
However, Consumer Reports did find 9 brands that met all the quality standards. Of those, the least expensive is WalMart's Spring Valley brand. The recommended dose costs just 17 cents a day.
"Omega 3 fatty acids can reduce the risk of heart attacks and stroke.. But most people can get enough by eating fatty fish at least twice a week" said Dr. Santa.
That includes salmon and sardines.
There is a warning about the capsules, they can interact with certain prescription drugs, including blood pressure medicine, so check with your doctor first.
