How to Get Fish Oil

Fish oil contains omega-3 fatty acids, which are essential fatty acids that you can only obtain from your diet. These acids are found naturally in fatty and oily fish, such as tuna, salmon and halibut. Omega-3 fatty acids are important for brain function, growth and development. Consuming fish oil may also help to reduce the risk of certain chronic diseases, such as cardiovascular diseases, cancer and arthritis. Although you can obtain omega-3 fatty acids from consuming some types of fish, you can also take a fish oil supplement.

PCBs Found in Fish Oil Supplements

Fish oil supplements contain omega-3 fatty acids, which are touted for their anti-inflammatory, heart-protective benefits. However, fish oil supplements have come under concern from environmental research groups who say the supplements contain polychlorinated biphenyls or PCBs. These harmful compounds have been detected in varying amounts in fish oil supplements. Manufacturers have taken extra steps to minimize PCBs. If you are concerned about your PCB intake, speak to your physician about the best supplement or method to take in fish oil.
