The Complete Guide to Omega 3: Benefits, Sources, and Dosage

Your body can't make it. Your brain depends on it. And most of us aren't getting enough of it. This is the essential guide to Omega 3.

Omega 3 fish oil capsules by Calm Era

Omega 3 fatty acids are among the most researched nutrients in modern science — and for good reason. From cardiovascular health to cognitive function, their influence on the body is profound and wide-reaching. Yet despite their importance, studies consistently show that the majority of people in the UK and Europe fall short of recommended intake levels.

At Calm Era, we believe that understanding what you put into your body is the first step to genuine wellbeing. So let's start at the beginning.

What Are Omega 3 Fatty Acids?

Omega 3s are polyunsaturated fats that your body cannot synthesise on its own — making them truly essential nutrients that must come from diet or supplementation. There are three key types:

  • EPA (eicosapentaenoic acid) — primarily anti-inflammatory, supports heart and mood health
  • DHA (docosahexaenoic acid) — critical for brain structure and function
  • ALA (alpha-linolenic acid) — found in plant sources; the body converts a small amount to EPA and DHA

The Science-Backed Benefits

Heart Health

Decades of research support Omega 3's role in cardiovascular health. Regular intake has been shown to reduce triglyceride levels, lower blood pressure, and decrease the risk of irregular heartbeat. The European Food Safety Authority (EFSA) recognises EPA and DHA as contributing to normal heart function.

Brain Function & Mental Clarity

DHA makes up approximately 40% of the polyunsaturated fatty acids in the brain. It supports cognitive function, memory, and may help reduce the risk of age-related mental decline. Emerging research also links adequate Omega 3 intake with improved mood and reduced symptoms of anxiety and depression.

Anti-Inflammatory Properties

Chronic low-grade inflammation underlies many modern health conditions. EPA in particular has powerful anti-inflammatory effects, helping to modulate the body's inflammatory response and support joint comfort and mobility.

Eye Health

DHA is a major structural component of the retina. Adequate intake supports visual acuity and may help protect against age-related macular degeneration.

Best Natural Sources of Omega 3

Fatty Fish (Richest Source)

  • Salmon — 1,500–2,000mg per 3.5oz serving
  • Sardines — 1,400mg per 3.5oz serving
  • Mackerel — 1,100mg per 3.5oz serving
  • Anchovies — 950mg per 3.5oz serving

Plant-Based Sources

  • Flaxseeds — 2,300mg ALA per tablespoon
  • Chia seeds — 1,700mg ALA per tablespoon
  • Walnuts — 2,500mg ALA per ounce
  • Hemp seeds — 1,100mg ALA per tablespoon

Note: Plant-based ALA converts to EPA and DHA at a very low rate (typically under 10%), making direct EPA/DHA sources — or supplementation — particularly important for those on plant-based diets.

Omega 3 supplement daily routine

Recommended Dosage

The optimal dosage varies based on individual needs and health goals:

  • General health: 250–500mg combined EPA and DHA daily
  • Heart health: 1,000mg combined EPA and DHA daily
  • High triglycerides: 2,000–4,000mg daily (under medical supervision)

Always consult with a healthcare professional before starting any supplement regimen, especially if you have existing health conditions or take medications.
