There was a moment several years ago when I was sitting in the doctor’s waiting room, waiting for the results of a routine general check-up. My cholesterol numbers are normal, my blood pressure is good, but the doctor looked at the screen and asked casually, “Do you eat fatty fish regularly, sir?” I shook my head. It turned out that the conversation grew a lot longer than I thought it would — about something we rarely talk about seriously: whether our bodies really get enough good fats every day.
We often focus on calories, sugar, or protein when talking about healthy eating. But there is one group of nutrients that is often overlooked even though its role is crucial: omega-3 fatty acids. Ironically, our bodies cannot produce it themselves. Omega-3 is classified as an “essential fatty acid” — a term that literally means the body must get it from outside, because our biological machinery is not equipped with the pathways to synthesize it from scratch.

Scientifically, omega-3 has several main forms: ALA (alpha-linolenic acid) which is mostly found in plant sources such as chia seeds and walnuts, and EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) which mostly come from deep sea fish such as salmon, sardines and mackerel. Of the three, EPA and DHA are the most researched and most relevant to two vital organs: the heart and brain.
For the heart, omega-3 works much like precision lubricant in a vehicle engine. It helps maintain the elasticity of blood vessels, lowers triglyceride levels, and reduces the tendency of blood to clot excessively. Think of blood vessels as highways — if their surfaces are stiff and full of plaque, blood flow is restricted and the risk of blockages increases. Omega-3 plays a role in keeping this “highway” flexible and smooth, so that the heart does not work harder than it should.
Meanwhile for the brain, the story is even more interesting. About 60% of the human brain structure is composed of fat, and DHA is one of the main structural components, especially in nerve cell membranes. In a way, DHA is the literal building block of our brain tissue — similar to how cement and rebar form the framework of a building. Without an adequate supply, communication between nerve cells (neurotransmission) can slow down, and some research has linked long-term omega-3 deficiency to decreased cognitive function and more easily disturbed mood.
The problem is, modern diets — especially in highly mobile urban areas — rarely provide ideal portions of fatty fish (at least twice a week, according to general recommendations from nutritionists). Busy work, limited access to quality fresh fish, or simply tastes that don’t match fish, make many people end up with an omega-3 deficit without realizing it. This is where fish oil supplements start to become relevant — not as a replacement for a healthy diet, but as a practical shortcut to closing the intake gaps that often occur in real life.
One that I see recommended quite often and have tried myself is Blackmores Omega 3 Fish Oil 1000mg. The EPA-DHA content in a fairly dense dose makes it practical to consume daily without having to recalculate fish portions every week.

If you are curious about how I compare several other brands of fish oil on the market – in terms of EPA-DHA content, price per capsule, to the fishy taste which is a common complaint – I have summarized the comparison in more detail on my personal blog.

What needs to be underlined is that any supplements – including fish oil – should still be consulted with a doctor or nutritionist, especially for those who are taking blood thinners or have certain medical conditions. Omega-3 is indeed beneficial, but excessive doses without supervision are not without risks.
In the end, maintaining a healthy heart and brain is not a matter of instant solutions, but rather small consistencies repeated every day — whether through diet, light exercise, enough sleep, or ensuring the body gets the essential nutrients it needs. Omega-3s are just one small piece of the larger healthy lifestyle puzzle, but this small piece is often the easiest to miss.
How about you? Have you been consuming fatty fish regularly enough, or have you just realized that there is a nutritional gap that has so far gone unnoticed? I’m curious about other readers’ experiences with this — please share in the comments.
