Do Fish Supplements Contain Mercury or Harmful Pollutants?

The Skinny On: Mercury and Fish Oil Supplements

Eating fish is a great way to get your fill of essential omega-3 fatty acids. This healthy fat can help fight obesity, improve your mood, prevent chronic aches and pains, and keep your heart healthy. If you're not a fan of preparing or eating fish, then you may opt for the convenience of fish oil capsules instead. You may have wondered how safe these supplements are when it comes to mercury levels or toxic pollutants found in some species of fish.

To find out,


Studies show that most fish oil supplements contain little or no mercury since they're made from cod, anchovies, and sardines. These types of fish are lower on the food chain, so they live shorter lives and accumulate less mercury. Most companies distill their fish oils too, which helps remove any contaminants such as dioxins or PCBs. So if you're worried about getting too much mercury from eating fish, taking fish oil supplements is a safe choice. Also, look for the USP seal on your nutritional supplements.
