Omega-3 fatty acids are healthy fats that need to be consumed through diet, given that the body can not produce them on its own. Benefits such as aiding weight loss, a healthy pregnancy, athletic recovery and thickening of the nails and hair have also been associated with omega-3s.

Conditions such as depression, inflammation, anxiety, attention deficit hyperactivity disorder, diabetes, arthritis, infertility, inflammatory bowel disease, Alzheimer’s disease, macular degeneration and skin problems such as psoriasis and eczema have also been pointed out as possible to be benefited by the presence of the substance in the diet.

Omega-3 deficiency, which can be seen in industrialized countries and people who consume many processed foods and hydrogenated oils or follow a vegetarian or vegan diet, causes problems such as poor memory, dry skin, heart problems, mood changes, joint pain and autoimmune disease.

Is Omega-3 good for high blood pressure?

A study by a researcher from Iceland and colleagues showed that consumption of three servings of salmon (which is a known source of omega-3s) has reduced the high blood pressure in overweight young people over a period of eight weeks.

This is not definitive proof that omega-3 is good for high blood pressure, but in the sense of lowering blood pressure, it is a preliminary result that is encouraging.

In the same vein, WebMD reported that findings have already pointed out that omega-3 fatty acids may contribute to lowering blood pressure.

In turn, the American Heart Association indicates that omega-3 fatty acids may slightly lower blood pressure. Omega-3 is considered a good fat and good fats can decrease inflammation, which can result in problems like hypertension.

Master in nutrition at public health Destiny Simmons wrote that omega-3 fatty acids help expand blood vessels, an effect that may also mean that omega-3s are good for high blood pressure.

In addition, fish oil (which is rich in omega-3) is possibly effective in preventing high blood pressure caused by a medicine called cyclosporin, used to prevent organ rejection after a transplant.

Research has analyzed experiments on the effects of fish oil on hypertension

The Journal of Hypertension analyzed 90 different experiments that studied the effects of fish oil on high blood pressure.

The research identified that most of the experiments included participants who were using high doses of fish oil and that, in this way, the product had a decrease effect in relation to blood pressure.

However, before you start taking high doses of fish oil, you should consult your doctor to see if the product really can help you with your high blood pressure case and what dosage is safe and effective for you. Even because eating too much fish oil can cause problems.

Metabolic syndrome

According to multiple studies, the symptoms of metabolic syndrome improve and may protect against diseases that are associated with the condition.

But what does high blood pressure have to do with it? It is that the metabolic syndrome is a set of risk factors like high blood pressure, abdominal obesity, high blood glucose, high triglycerides and low levels of good cholesterol (HDL) to develop problems such as heart disease, stroke or diabetes.

Drug interactions

Fish oil, which is rich in omega-3s as we have seen here, can interact with medications used to treat high blood pressure.

The combination of fish oil and medicines for high blood pressure can make your blood pressure too low.

Patients who use fish oil supplements along with high blood pressure medications may experience symptoms such as dizziness, vertigo, fainting, blurred vision, rapid and shallow breathing, concentration problems, fatigue, depression, pallor and thirst.

Intake of excessive dosages of fish oil supplements or high blood pressure medications can also cause symptoms of hypotension (low blood pressure) even when they are not taken in combination.

So before using omega-3, check with your doctor if it can not interact with any high-pressure medicine you are using or any other medicine, supplement or natural product that you are currently using.


What we put here serves as information, however, does not go beyond this sphere and can never replace the prescription of a doctor. More important than knowing that omega-3s are good for high blood pressure is understanding how full hypertension treatment should be.

So if you know that you are suffering from the problem, you should follow the doctor’s recommended treatment, asking about how and if omega-3 can help you, if it is not contraindicated for you, and at what dosage you should use it it, especially in the case of supplements.

The recommendation is for any other condition for which you think about using omega-3 to aid your treatment.
