1. What Is Omega-3?

Omega-3 fatty acids are essential fats that your body cannot produce on its own.
They support heart health, brain function, and inflammation control.
The main types are EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid), mostly found in fish oil.

2. Recommended Daily Dosage

For healthy adults, experts recommend:

  • 250–500 mg of combined EPA + DHA per day for general health.

  • Up to 1,000 mg (1 g) for people with heart conditions or high inflammation.

Those who eat oily fish (like salmon or mackerel) twice a week may not need extra supplements.

3. How and When to Take Omega-3

To improve absorption and reduce stomach discomfort:

  • Take it with meals, preferably those containing fat.

  • Morning or evening doesn’t matter — consistency is key.

  • Avoid taking it on an empty stomach, as it may cause mild nausea.

You can also take 500–1,000 mg on alternate days if you eat a balanced diet rich in fish, nuts, and seeds.

4. Possible Side Effects

Omega-3 is generally safe, but high doses (over 3,000 mg/day) may cause:

  • Mild stomach upset or nausea

  • Fishy aftertaste or burping

  • Thinner blood and slower clotting

If you take blood-thinning medications or have surgery planned, consult your doctor before use.

5. Tips for Safe Long-Term Use

  • Choose purified fish oil or certified supplements tested for mercury and heavy metals.

  • Store in a cool, dark place to prevent oxidation.

  • Take breaks every few months if you’re on high doses for long periods.

  • Combine with a healthy diet rich in omega-3 sources like flaxseed, walnuts, and fish.

6. Final Thoughts

Omega-3 offers strong benefits for heart, brain, and immune health, but balance is key.
For most people, 500–1,000 mg daily or every other day is enough to see lasting results without side effects.
Take it smartly, stay consistent, and your body will thank you.
