Omega-3 supplements have little effect on cardiovascular disease and mortality

omega-3 supplements

I have been skeptical of supplements for a long period of time. Supplements are generally of low quality, they don’t prevent or cure cancer, they don’t prevent colds, they can’t boost the immune system, and they don’t prevent heart disease. Now there is a powerful review of omega-3 supplements that shows that it has little effect on cardiovascular disease.

Unless one has a chronic disease or is chronically malnourished, there are precious few instances where supplements are necessary. A couple of cases where supplements may be critical include prenatal folic acid supplements to prevent neurological defects in the developing fetus, vitamin C to prevent scurvy, and vitamin D supplements for individuals who do not produce enough endogenous vitamin D. In each of these cases, however, supplements are necessary to counteract a micronutrient deficiency that results from a chronic deficiency in the diet.

The benefits of omega-3 supplements have always been intriguing to me because it is a supplement that I thought might be useful for improving cardiovascular health. But as I reviewed before, the evidence seemed awfully weak. With this new study, there may be no evidence whatsoever supporting the use of omega-3 supplements, at least for cardiovascular disease.

Big supplement profits – making boatloads of money in the name of pseudoscience

As a vaccine supporter, I get accused of being a shill for Big Pharma all the time. My basement is filled with gold bars shipped to me in remuneration for my services to the corporate hooligans – wait. No basement, no gold bars. On the other hand, Big Supplement, those companies who make money off of people who think that if they take this one vitamin to prevent all cancer, makes a a ton of money selling this junk medicine to unwary and unsophisticated consumers.

Let’s take a moment and look at the differences between Big Pharma and Big Supplement. The former has to work hard and provide evidence of what its drugs do, while the latter basically can sit around and throw darts at various claims, then randomly assign those claims to some new or old supplement.

Benefits of omega 3 fish oil – something’s fishy

I have been skeptical of supplements for a long period of time. The supplements are generally of low quality, they don’t prevent or cure cancer, they don’t prevent colds, they can’t boost the immune system, and they don’t prevent heart disease. Now it’s the time to take a look at the benefits of omega 3 fish oil, something that is claimed by Big Supplement over and over. Is there anything there?

Unless one has a chronic disease or is chronically malnourished, there are precious few instances where supplements are necessary. A couple of cases where supplements may be critical include prenatal folic acid supplements to prevent neurological defects in the developing fetus and vitamin D supplements for individuals who do not produce enough endogenous vitamin D. However, just to keep this in perspective, excess folic acid for a long period of time may be correlated with increased rates of certain cancers.

The benefits of omega 3 fish oil has always been intriguing to me, because it is a supplement that I thought might be useful to improving health, especially cardiovascular health. Omega 3 fatty acids are generally found in fish, as it is produced by the phytoplankton that is the primary food source of much of the prey for larger fish and bio-accumulates up the food chain. However, for humans, there are other sources of omega 3 oils including walnuts and edible seeds, eggs, and other non-fish foods.

Epidemiological studies done in the late 1980s seem to indicate relatively low death rates due to cardiovascular disease in Inuit populations with high seafood consumption. These results began the rush to consume omega 3 supplements, and created a booming supplement industry.

However, since publication of those initial studies, much research has been done on seafood and heart disease. And the results don’t give much credence to the cardiovascular benefits of omega 3 fish oils as a useful supplement.
