At a Glance

  • Omega-3s (EPA, DHA and ALA) are essential fats the body needs from food.
  • DHA is a key building block of the brain and the retina.
  • Oily fish twice a week is the richest source; flaxseed and walnuts supply ALA.
  • Supplements can help fill the gap, especially for vegetarians.

Not all fats are bad. Omega-3 fatty acids are “good fats” your body needs for healthy cells, but can’t make in sufficient amounts on its own. There are three main types: ALA (from plants), and EPA and DHA (mainly from fish and algae).

Where omega-3s work in your body

Heart

EPA and DHA help lower triglycerides and support healthy blood vessels.

Brain

DHA is a major structural fat in the brain and supports memory and focus.

Eyes

DHA is concentrated in the retina and is vital for normal vision.

Pregnancy

DHA supports the development of the baby’s brain and eyes.

Best food sources

  • Oily fish: mackerel (bangda), sardines (mathi), salmon, hilsa, tuna – aim for two servings a week.
  • Seeds: flaxseed (alsi), chia seeds – ground flaxseed is absorbed better.
  • Nuts: walnuts are the best nut source of ALA.
  • Others: mustard oil, soybean, rajma and leafy greens contain smaller amounts.
For vegetarians

The body converts only a small fraction of plant ALA into EPA and DHA. Vegetarians may benefit from regular flaxseed and walnuts – and supplements where advised by a doctor.

Should you take a supplement?

If you rarely eat fish, an omega-3 supplement – capsules or a family-friendly syrup – is a convenient way to get DHA and EPA. Formulas that combine omega-3s with multivitamins and antioxidants like lycopene can support overall wellbeing.

Talk to your doctor if…

you take blood-thinning medicines, have a bleeding disorder or are scheduled for surgery, as high doses of omega-3 can affect blood clotting.

A handful of walnuts, a spoon of flaxseed and fish twice a week – small habits, big returns for your heart and brain.

Frequently Asked Questions

When is the best time to take omega-3?

With a meal containing some fat. This improves absorption and reduces the chance of a fishy aftertaste.

Can children take omega-3?

Yes, in age-appropriate doses. Syrups are easier for children – check the label and ask your paediatrician.

Does cooking destroy omega-3?

Gentle cooking like steaming or baking preserves most omega-3s. Deep-frying reduces them.
