Pro Tip: Algae, frequently enough consumed as a supplement, is the original source of omega-3 in fish, offering a plant-based alternative for DHA and EPA.

plant-Based ALA Omega-3 Sources

• Green Leafy Vegetables: Cabbage, spinach, and Brussels sprouts.
• Vegetable Oils: Flaxseed and rapeseed oils (commonly found in canola oil).
• Nuts and Seeds: Flax seeds, chia seeds, and walnuts.

Are You Getting Enough Omega-3?

While there’s no specific official guideline for ALA, EPA, and DHA intake, health organizations offer recommendations.

The UK National Health Service (NHS) suggests consuming at least two portions of fish per week, including one portion of oily fish, to ensure adequate EPA and DHA intake.

However, studies show that only a small percentage of the population meets these recommendations.

Did You Know? Farmed fish may have lower Omega-3 levels than wild-caught fish due to differences in their diets.

Jonathan Napier, Science Director at Rothamsted Research, notes that obtaining enough EPA and DHA solely from fish is becoming challenging due to the prevalence of fish farming.
