Is Taking Fish Oil Harmful to Your Health?

Taking fish oil might be harmful to your health, as eating fatty fish such as salmon and mackerel or taking a fish oil supplement has been linked with an increase in health problems and faster aging, even though it was previously thought to improve health. One study found that consuming fish oil increased the likelihood of men developing prostate cancer by about 43%. Fish oil also might speed up aging, as animals that consumed fish oil had their life expectancy decrease by 14%. The potentially harmful effects of fish oil are thought to be caused by an unknown occurrence in how the body breaks down the molecules in the omega-3 fatty acids found in the oil.

  • In the US, more than $1 billion US Dollars is spent on fish oil supplements each year.
