WHY IS OMEGA-3 FATTY ACID ESSENTIAL FOR THE BODY?

Omega-3 fatty acids are considered essential because they perform important functions throughout the body, while your body cannot make enough of certain omega-3s on its own.

Why does the body need omega-3?

1. 🧠 Supports the brain and nervous system
DHA is a major structural component of brain cell membranes. It helps maintain normal brain structure, communication between nerve cells, and cognitive function.

2. ❤️ Supports cardiovascular health
EPA and DHA can help:

• Lower blood triglycerides
• Support normal heart rhythm
• Support healthy blood-vessel function
• Modulate inflammation

3. 👁️ Supports eye health
DHA is concentrated in the retina and is important for maintaining normal retinal structure and visual function.

4. 🔥 Helps regulate inflammation
EPA and DHA are used to produce signaling molecules that help regulate the body's inflammatory response. This doesn't mean omega-3 is simply an "anti-inflammatory"; rather, it helps the body control and resolve inflammation appropriately.

5. 🧬 Maintains cell membranes
Omega-3s are incorporated into the membranes surrounding cells. They influence membrane flexibility and how cells communicate with one another.

6. 🤰 Important during pregnancy and early development
DHA is particularly important for development of the baby's brain and eyes.

An important distinction

There are three major omega-3s:

Omega-3	Main sources	Why it matters
ALA	Flaxseed, chia, walnuts	Essential dietary fatty acid; precursor to EPA/DHA
EPA	Fatty fish, fish oil	Cardiovascular and inflammatory signaling
DHA	Fatty fish, algae	Brain, eyes and nervous system

The body cannot make ALA, so it is an essential fatty acid. It can convert ALA into EPA and DHA, but the conversion is relatively inefficient. Therefore, obtaining EPA and DHA directly from fish or algae can be useful.

In simple terms: Omega-3 is important because it provides the body with the building blocks and signaling molecules needed to maintain healthy cells, brain function, vision, cardiovascular function and balanced inflammatory responses.
