Omega 3 fatty acids are essential fats that play a vital role in maintaining optimal health. One of the best sources of omega-3 fatty acids is fish oil. Fish oil contains two important types of omega-3 fatty acids: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids are not produced by the body and must be obtained through dietary sources. In this blog post, we will delve deep into the world of Omega-3 Fish Oil, how fish oil is made, dispelling myths and revealing science-backed facts to help you make the best choices for your health.

Health Benefits of Omega-3 Fish Oil

Omega-3 fish oil is packed with a wide range of health benefits. Let's take a closer look at what does fish oil do in terms of some of the key advantages:

1. Cardiovascular benefits

Omega-3 fish oil has been shown to be effective in reducing the risk of heart disease and improving cardiovascular health.

  • It helps lower triglyceride levels, which contributes to heart problems.
  • Regular consumption of fish oil may help lower blood pressure.
  • It also aids in improving overall heart function and reducing the risk of abnormal heart rhythms.

2. Brain Function and Mental Health Benefits

The omega-3 fatty acids found in fish oil are crucial for brain development and function.

  • The omega-3 fatty acids found in fish oil have been linked to improved cognitive function and memory.
  • Fish oil also helps reduce the risk of age-related mental decline and conditions like Alzheimer's disease.
  • It has shown promising results in alleviating symptoms of depression and anxiety.

3. Joint Health and Anti-inflammatory Properties

Omega-3 fish oil contains anti-inflammatory properties that can help with joint pain and stiffness. It is beneficial for individuals suffering from conditions such as arthritis or rheumatoid arthritis.

Regular intake of fish oil supplements may help reduce inflammation in the body.

Debunking Common Myths about Omega-3 Fish Oil

Omega 3 fatty acids have gained widespread popularity for their potential health benefits, but along with the facts, a number of myths and misconceptions have emerged. Let's unravel some of these myths to provide a clearer understanding of omega-3 fish oil.

Myth 1: All Fish Oils are the Same

Fact: Not all fish oils are created equal. The quality and purity of fish oil can vary depending on factors such as the source, processing methods, and manufacturing practices. Look for reputable brands that adhere to strict quality standards and have their products tested by third-party laboratories.

Myth 2: Fish Oil Supplements are Not Necessary if You Consume a Balanced Diet

Fact: While it is ideal to obtain nutrients from whole foods, it can be challenging to meet the recommended  omega-3 intake solely through diet. Fish oil supplements provide a convenient and reliable way to ensure an adequate intake of omega-3 fatty acids, especially for individuals who do not regularly consume fatty fish.

Myth 3: Taking Fish Oil can Increase the Risk of Bleeding or Thinning the Blood

Fact: Omega-3 fish oil can have a mild blood-thinning effect; however, it is generally safe for most people, including those taking blood-thinning medications. It is always advisable to consult your healthcare provider before starting any new supplement or if you have a bleeding disorder.

Myth 4: Fish Oil Causes Weight Gain

Fact: Fish oil supplements are not known to cause weight gain. Research suggests that omega-3 fatty acids may help with  weight management by reducing inflammation, promoting satiety, and improving fat metabolism.

Myth 5: Fish Oil Contains High Levels of Mercury

Fact: While certain types of fish can contain mercury, reputable fish oil supplements go through a purification process that removes impurities, including heavy metals like mercury. Look for products that are certified to be free from contaminants.

Myth 6: Fish Oil Causes "Fishy Burps" and Gastrointestinal Issues

Fact: This myth is partially true but can be easily mitigated by choosing high-quality, enteric-coated fish oil capsules or liquid forms that are less likely to cause these side effects.

Myth 7: Fish Oil is Only Beneficial for Heart Health

Fact: What does fish oil do for overall health? While omega-3 fatty acids are indeed beneficial for cardiovascular health, they also play a crucial role in brain function, joint health, and reducing inflammation throughout the body.

Myth 8: Fish Oil is Made from Fish Liver

Fact: It is important to understand how is fish oil made. Fish oil is made from the fatty tissues of oily fish like salmon, mackerel, and sardines, not their livers. The liver is actually where most toxins accumulate, so it is not used in fish oil production.

Myth 9: Consuming More Fish Oil will Lead to Better Health Outcomes

Fact: While omega-3 fish oil is beneficial for overall health, it's important to follow the recommended dosage. Consuming excessive amounts can lead to adverse effects such as gastrointestinal issues, increased bleeding risk, and impaired immune function.


In conclusion, the importance of omega-3 fatty acids and the role of fish oil supplementation cannot be overstated. While it's always best to obtain nutrients from whole foods, fish oil contains nutrients that are beneficial for those who don't consume enough fatty fish. However, it's important to choose high-quality supplements and consult with a healthcare professional before starting any new regimen. By prioritising our intake of omega-3s, we can contribute to our overall health and well-being.

Q. Are there any side effects or risks associated with fish oil?

While fish oil is generally safe for most people when taken in appropriate doses, it can cause some minor side effects such as fishy aftertaste, diarrhoea, or indigestion. Additionally, individuals taking blood-thinning medications should consult their healthcare provider before starting fish oil supplements.

While it is possible to get omega-3 fatty acids from certain foods, many people find it challenging to meet their daily requirements through diet alone. To know if you are taking an adequate amount of omega-2, consult a doctor.

While it's possible to obtain omega-3 fatty acids from dietary sources like fatty fish, some individuals may find it challenging to meet their recommended intake through food alone. In such cases, fish oil supplements can be a convenient option to ensure an adequate intake of omega-3s.
