How Safe Are Fish Oil Supplements

Concerns about health are at an all-time high nowadays. Research has shown that eating fish can lower the risk of heart disease, but at the same time other studies have concluded that fish meat has higher-than-usual levels of mercury and PCB, which may cause adverse effects in your body. So if you want the benefits of fish without the fear of consuming unwanted metals and chemicals, you can take fish oil supplements instead.

The benefits of fish oil without contaminants

Doctors advise that we take a regular dosage of fish oil supplements to get omega-3 fatty acids, which may reduce the risk of coronary heart disease among other important health benefits.

Fish oil supplements have been tested by independent consumer groups, who have concluded that these supplements do not have mercury or PCBs. Also, the fish used to make pills are usually younger and smaller than the fish we eat. This means they have had less time to accumulate toxins.

Fish oil supplements are also convenient because you get enough omega-3 fatty acids, which you may be lacking if you eat even the recommended amount of fatty fish servings in a day.

Not all fish oil supplements are the same

However, just as there are good eggs and bad eggs, some fish oil supplements can actually do more harm to your body. Several studies have shown that unpurified fish oil supplements still contain unsafe levels of environmental contaminants.

This is why you need to read the label and make sure that you are getting purified supplements to avoid consuming concentrated amounts of toxins along with your omega-3.

Fish oil supplements can still harm the heart?

A recent study have gotten researchers scratching their heads after finding out that patients with implanted defibrillator devices who regularly take fish oil supplements had sooner and recurrent bouts of ventricular tachycardia, wherein a heart ventricle quivers to the point that it prevents it from pumping blood, compared to those patients who take the placebo.

The study was conducted by a controlled trial in 200 patients who were randomized to take either fish oil or placebo.

Does this study make fish oil supplements harmful to your health? Probably not, but people with an implanted defibrillator would be advised not to take fish oil supplements and instead find alternative products that also contain omega-3 fatty acids such as flax seed oil or marine algae supplements.
