Fish oil is one of the most commonly consumed dietary supplements. 

If you’re one of the people taking fish oil vitamins, or you’re thinking about buying it, you may be curious about the exact benefits of fish oil – and whether there are any downsides to taking these supplements. So, we put together this article on what you should know about fish oil vitamins – from its uses, benefits, potential side effects, and more. 

What is Fish Oil?

Fish oil can be obtained by eating fish or taking fish oil vitamins. Fish that are especially rich in the beneficial oils known as omega-3 fatty acids include tuna, mackerel, salmon, and cod liver. Two of the most important omega-3 fatty acids contained in fish oil are docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). 

A lot of the benefits of fish oil comes from the omega-3 fatty acids that it contains. DHA and EPA are involved in regulation numerous biological processes, such as brain function, the inflammatory response, and various metabolic signaling pathways. 

Interestingly, the body does not produce its own omega-3 fatty acids – it must be consumed in the diet. The World Health Organization (WHO) recommends eating 1 to 2 portions of fish per week. However, if you don’t eat 1 to 2 servings of fish per week, taking fish oil vitamins can help you get enough omega-3s. 

What is fish oil vitamins? Fish oil vitamins contain omega-3 polyunsaturated fatty acids. Omega-3 polyunsaturated fatty acids can be found in oils from certain types of fish, vegetables, and other plant sources. Fish oil vitamins come in capsule, pill, and liquid form. People mostly take fish oil vitamins to reduce the risk of strokes and heart attacks, to treat high blood pressure, and to improve symptoms of rheumatoid arthritis. 

Benefits of Fish Oil Vitamins

Are fish oil vitamins good for you? 

Below, we list down 5 potential health benefits of fish oil, according to science. 

  1. Fish oil may help support heart health. Heart disease is the leading cause of death across the world. Studies show that people who eat a lot of fish have much lower rates of heart problems [1, 2]. Several risk factors for heart disease appear to be reduced by the consumption of fish, fish oil, or fish oil vitamins. The benefits of fish oil for heart health include:
  •  It can lower triglycerides by about 15% to 30%[3]
  • It can help lower blood pressure levels[4]
  • It may prevent the formation of plaques that cause your arteries to harden and make arterial plaques safer and more stable in people who already have them[5, 6]
  • It can increase levels of ‘good’ HDL cholesterol[7]
  1. Fish oil may help fight chronic inflammation. Oils extracted from fatty fish like mackerel, anchovies, and sardines provide two types of omega-3 fatty acids – docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) – that are known to help lower inflammation[8], and generally improve inflammatory conditions in the body. Because chronic, low-grade inflammation is linked with premature aging and certain diseases, fish-derived omega-3s may provide a broad spectrum of health protection. 
  1. Fish oil may help with weight loss. Obesity is defined as having a body mass index (BMI) that’s greater than 30. Globally, approximately 39% of adults are overweight, while 13% are obese[9]. Obesity can significantly increase your risk of other diseases, including type 2 diabetes, heart disease, and cancer. Combined with exercise, fish oil vitamins may improve body composition and risk factors for heart disease in obese individuals[10]. Moreover, some studies show that fish oil vitamins, in combination with a healthy diet and exercise, can help you lose weight[11].
  1. Fish oil may improve bone health. Bones can begin to lose their essential minerals during old age, making them more likely to break. This can lead to conditions like osteoarthritis and osteoporosis. Vitamin D and calcium are crucial for bone health, but some studies found that omega-3 fatty acids may also help. Studies show that people with higher omega-3 intakes may have better bone mineral density[12]. Several small studies also suggest that fish oil supplements may reduce the markers of bone breakdown, which may prevent bone disease[13]
  1. Fish oil may keep your brain sharp. One study revealed that fish oil improved cognitive performance in healthy adults between the ages of 51 – 72[14], in just 5 weeks compared with the effects of a placebo. Research has also linked high blood levels of omega-3s with a lower risk of anxiety and depression[15]. What’s more, when used in combination with standard antidepressant therapies, fish oil supplementation has been shown to help treat depression compared to a placebo[16]
