Why Omega-3 Fatty Acids Are So Important

Omega-3 fatty acids are among the most important nutrients for our health. They support heart function, reduce inflammation and are important for brain function. Since our body cannot produce them itself, we must obtain them through diet or supplements.

Key Points at a Glance

  • EPA (Eicosapentaenoic acid): Important for heart health and anti-inflammation
  • DHA (Docosahexaenoic acid): Essential for brain and eye function
  • Molecular distillation: Removes heavy metals and contaminants
  • Triglyceride form: Better bioavailability than ethyl esters

Scientifically Proven Benefits of Omega-3

Heart Health

Reduces triglycerides, supports normal heart function and may prevent heart rhythm disorders.

Brain Function

DHA is important for memory, concentration and may protect against age-related cognitive decline.

Anti-inflammatory

EPA reduces inflammatory markers in the body and may help with chronic inflammation.

Eye Health

DHA is an important building block of the retina and may protect against age-related macular degeneration.
