While krill oil is great for many things, should you be concerned about the potential dangers of krill oil supplements?
Krill oil is often promoted as a healthier, safer alternative to fish oil supplements because the oil is rich in omega-3 fatty acids and comes with many of the same health benefits. The oil is sourced from small crustaceans found naturally in cold ocean waters, primarily in Japan, Antarctica and Canada. The oil is proven to help lower cholesterol levels, reduce inflammation and take the stickiness out of blood cells so that they’re less likely to clot. Many users also believe that they gain physical energy and mental focus by taking fish oil or krill oil supplements.
The primary concern with fish oil supplements is that they’re potentially contaminated with heavy metals and other toxins. These toxins come from pollution in the oceans, so they’re in the fish prior to being caught and processed for their oil. Since krill come from the same waters, are there krill oil dangers that you need to worry about?
Mercury and other heavy metals are the primary contaminant for fish oil supplements, and there is a chance that those metals are in some krill supplements as well. The arguments in favor of the krill is that these crustaceans are at the bottom of the food chain and are probably exposed to lower levels of contaminants as a result.
Since there is no scientific proof of this, the FDA has recommended that pregnant women and those of childbearing age limit their consumption of fish. There are no FDA warnings or recommendations for krill oil specifically, but you can guess that limiting consumption of any seafood supplement while pregnant is wise. This is a good rule to follow until further research is completed on the safety of krill oil.
What if you’re a man or a woman not planning to have a baby anytime soon? It’s best to assume that some krill oil supplements may contain contaminants. Whether you believe that these supplements are safer than fish oil supplements or not, it’s important to do your research before selecting a supplement.
Look for brands that openly reveal the methods used to safely harvest and process their krill oil. You may pay a bit more for a product sourced from the highest quality krill from the cleanest oceans, but your health is worth that investment.
Since krill oil is a seafood product, you shouldn’t take it if you have a known or suspected seafood allergy. If you have taken fish oil supplements and experienced stomach issues or other side effects, then there’s a chance that you’ll have the same reaction to krill oil.
Krill oil is proven to reduce the risk of blood clotting, and many professionals reason that this means it thins the blood. While more research is needed to determine if krill oil thins blood, it’s best not to take this supplement before or after surgery. If you take medication that also thins the blood or suffer from a medical condition that may cause excessive bleeding, you should check with your doctor before taking a krill oil supplement.
For almost all users, the benefits outweigh the potential dangers of krill oil supplements. The key is to find high-quality supplements that are properly processed to eliminate potential toxins. This isn’t a product that you want to buy based on the lowest possible price. Quality is your primary concern.
