Alpha-Linolenic Acid

Definition

Short-chain 18-carbon polyunsaturated omega-3 fatty acid, precursor to long-chain omega-3 fatty acids. It's the essential fatty acid of plant origin that the body cannot synthesize.

How it works

Alpha-Linolenic Acid (ALA) is an essential fatty acid that the body cannot produce and must be obtained through nutrition. The body can convert it into long-chain omega-3 fatty acids like EPA and DHA, although this conversion is limited (5-10% only). Therefore, it's essential to consume both ALA sources and direct EPA/DHA sources. ALA plays a fundamental role in cellular membrane structure and brain function.

Role

Essential precursor to long-chain omega-3 fatty acids and cellular membrane component.

Examples

• Flaxseeds
• Chia seeds
• Nuts
• Rapeseed oil
• Spinach
• Flaxseed oil

Recommendations

Consume a daily serving of nuts (30g) or a tablespoon of milled flaxseeds. Diversify plant-based ALA sources and supplement with direct EPA/DHA sources like fatty fish to optimize your omega-3 intake.

Key takeaway

ALA is the essential plant-derived omega-3 fatty acid, but its conversion to EPA/DHA is limited, making it essential to diversify sources.
