What is Omega-3, And Why Is It Important For Human Health?

What is an essential fatty acid?

Essential fatty acids (EFAs) are fats that the human body cannot synthesize on its own and therefore must be obtained from external sources. They play important roles in many metabolic processes related to cardiovascular diseases, inflammation, and neurological functions.

One of these is ALA (Alpha-Linolenic Acid), an omega-3 fatty acid and precursor of EPA and DHA.

Omega-3 fatty acids contribute to:

  • Proper functioning of the nervous system
  • Regulation of heart function and blood pressure
  • Maintenance of cardiovascular health
  • Regulation of fat metabolism
  • Anti-inflammatory processes

How should omega-3 be consumed?

Maintaining nutritional balance is essential for protecting the body and supporting energy metabolism.

How can omega-3 deficiency be identified?

The Omega-3 Index in Erythrocytes is a specialized test used to assess omega-3 levels.

Results:

  • Below 4%: High cardiovascular risk
  • 4–8%: Intermediate range
  • Above 8%: Ideal range

Possible signs of deficiency:

  • Fatigue
  • Dry skin
  • Chronic inflammation

How should we decide on supplementation?

Healthy adults: 250–500 mg/day EPA + DHA
If eating fish less than twice weekly: 500–1000 mg/day
If cardiovascular risk or high triglycerides exist (with medical supervision): 1000–2000 mg/day
One serving of salmon provides about 1000–1500 mg EPA + DHA.
Consuming 2–3 servings of fatty fish weekly is generally sufficient.
Daily doses above 3000 mg should only be used under medical supervision and ideally after testing.

Omega 3 takviyesine nasıl karar vermeliyiz?

Önce test yaptırmak en doğrusu olsa da, bu olanak yoksa, sadece sağlıklı bir yetişkini koruma amaçlı 250-500 mg/gün EPA+DHA alımı, Haftada en az 2 günden az balık yiyenler için günde 500-1000 mg alımı, Kalp damar riski, kan trigliserit yüksekliği varsa doktora danışılarak 100-2000 mg alınması uygundur. Beslenme olarak düşünüldüğünde 1 posiyon somonda: 1000-1500 EPA+DHA vardır.

Haftada 2-3 balık porsiyonu ise kişiyi koruyucu seviyeye ulaştırır.
Günde 3000 mg takviye almak (doktor ve test ile teyid edilerek alınmalıdır).
