Despite many medical professionals stand by their belief on the health benefits brought by fish oil products, it’s still a known fact around the medical community including the fish oil manufacturing community that the United States Food and Drug Administration still hasn’t given fish oil products a ‘thumbs up’ when it comes to its health benefits. This is because there are still cases that claim of fish oil’s side effects.
Admittedly, there are a handful of fish oil products like Nordic Naturals’ Nordic Naturals DHA that receive acclaim when it comes to their positive benefits on individuals who regular take them. These types of products bank on the potency of Omega-3 fatty acid in their products that is, unmistakably, very beneficial to our health. Omega-3 fatty acid can be found in other supplements like memory vitamins and weight loss products. Even though Omega-3 has numerous health benefits excessive consumption of it can increase incidence of bleeding and increase the risk of hemorrhagic stroke.
But still, we cannot deny the fact that there are, just like prescription drugs, side effects that can be brought by fish oil. Fish oil supplements have undergone some scrutiny in recent years. In 2006, Food Standards Agency of UK and the Food Safety Authority of Ireland reported the presence of PCB that exceeded the strict European limits in certain fish oil products. In March of 2010, a lawsuit was filed by a California environmental group against eight popular fish oil supplements brands because they contained excessive levels of polychlorinated biphenyl (PCB).
Fish oil is commonly extracted from the body of the fish but there are fish oil products where the oil is extracted from the liver. Since the liver is the filtering and detoxifying organ, PCB content is expected to be much higher. Fish liver oil also contains Omega-3 but is also an active source of vitamin A. Although vitamin A is good for the body but excess levels of it can lead to Hypervitaminosis A. Excessive vitamin A can cause liver problems, hair loss, skin discoloration and birth defects.
With these facts, it is better to be on alert and read the labels of your fish oil dietary supplement. Scrutinize the labels by looking for the source of fish oil – the fish and the parts of the fish – as well as the process it took to extract the oil. It is never a dumb thing to double check.
