Is Fish Oil Safe?

Question:
Is fish oil safe? Is it contaminated with mercury and PCBs?

Is Fish Oil Safe? -- fish oil capsules up close
Answer:
ConsumerLab.com's tests of fish oil supplements have found none to contain mercury and most, although not all, to have only trace levels of PCBs (which can't be fully avoided since PCBs are found in water everywhere). A serving of fish meat is likely to contain far more contamination than a fish oil supplement. However, we have found some supplements to contain less fish oil than listed and some to be spoiled. In addition, the enteric coatings on some supplements have not worked properly.

Clinical studies have shown fish oil to be safe, but it is recommended that you get no more than 2 grams (2,000 mg) of omega-3 fatty acids (EPA and DHA) from fish oil supplements per day.

For details, including our test results and comparisons of fish oil supplements and dosage recommendations, see our Fish Oil Supplements Review.

In know that fis oil as a supplement is highly promoted , realizing the contamination of many kinds of fish.
I know that a lot is published about the benefit of fish oil, but there are also publications which doubt these benefits.
Anyhow: fish oil is a "drug" as it is distilled oil from the fish and the meat of the fish is not consumed and I suppose one can't even guess what the difference is between whole fish [in ideal clean circumstances] and a part of the fish [just the oil]
The future may teach us, like happened with so many extracted products.
If you have more information about this issue then please publish this for our readers. Thanks
