🧠 What Are Omega-3 Fatty Acids?
Omega-3 fatty acids are essential polyunsaturated fats that play a crucial role in your body and brain. Since the body can’t produce them on its own, you must get them from food or supplements. The three main types include:
- ALA (Alpha-linolenic acid): Found in plants like flaxseeds and walnuts.
- EPA (Eicosapentaenoic acid) & DHA (Docosahexaenoic acid): Found in fatty fish and algae.

Decades of research show a strong link between omega-3 intake and reduced cardiovascular risks. Benefits include:
- 🩸 Lower triglyceride levels
- ❤️ Reduced blood pressure
- 🔥 Decreased inflammation
- 🧠 Improved endothelial function (lining of blood vessels)
- 💓 Prevention of arterial plaque buildup
According to the National Institutes of Health (NIH), omega-3s help prevent arrhythmias and lower the risk of sudden cardiac death.
