Omega-3 Fatty Acid: 21 Science-Based Benefits, Uses, Sources & Prices

What Are Omega-3 Fatty Acids?

what-are-omega-3-fatty-acids

Omega-3 fatty acids are polyunsaturated fats classified into three main types:

Type	Source	Benefits
ALA (Alpha-Linolenic Acid)	Flaxseeds, chia seeds, walnuts	Supports heart health, anti-inflammatory
EPA (Eicosapentaenoic Acid)	Fatty fish (salmon, sardines), fish oil	Reduces inflammation, improves mental health
DHA (Docosahexaenoic Acid)	Fish, algae	Brain development, eye health, pregnancy support

These fats play a critical role in cellular health, reducing cardiovascular risks, and enhancing brain function, making them indispensable for all age groups.

Why Omega-3 is Important for Health

Despite the availability of modern diets, omega-3 deficiency is common in Pakistan, especially among urban populations, due to low fish consumption and high processed food intake. Deficiency can lead to:

Fatigue and low energy
Poor heart health
Joint inflammation
Cognitive decline
Mood disorders

Doctors often recommend omega-3 supplementation when dietary intake is insufficient, particularly in high-risk groups like pregnant women, children, and heart patients.
