Fish oil is one of the most commonly consumed dietary supplements.
It’s rich in omega-3 fatty acids, which are very important for your health.
If you don’t eat a lot of oily fish, taking a fish oil supplement could help you get enough omega-3 fatty acids.
1. May Support Heart Health
Heart disease is the leading cause of death worldwide.
Studies show that people who eat a lot of fish have much lower rates of heart disease (8, 9, 10).
Multiple risk factors for heart disease appear to be reduced by consumption of fish or fish oil. The benefits of fish oil for heart health include:
Cholesterol levels: It can increase levels of “good” HDL cholesterol. However, it does not appear to
reduce levels of “bad” LDL cholesterol.
Triglycerides: It can lower triglycerides by about 15–30%.
Blood pressure: Even in small doses, it helps reduce blood pressure in people with elevated levels.
Plaque: It may prevent the plaques that cause your arteries to harden, as well as make arterial plaques more stable and safer in those who already have them.
Fatal arrhythmias: In people who are at risk, it may reduce fatal arrhythmia events. Arrhythmias are abnormal heart rhythms that can cause heart attacks in certain cases.
Although fish oil supplements can improve many of the risk factors for heart disease, there is no clear evidence that it can prevent heart attacks or strokes.
