Docosapentaenoic acid

Docosapentaenoic acid (DPA) is an Omega-3 fatty acid, the 'missing link' between the well-known EPA (heart health) and DHA (brain health). While often found in fish and marine oils, a specific plant-based version (from algae) offers a clean, sustainable alternative. Unlike standard plant Omega-3s (ALA), DPA is structurally closer to the Omega-3s found in our tissues, making it highly effective. It is unique because it can be recycled in the body longer than other fatty acids, offering sustained support for your cellular health.

Health Benefits & Sources

Why You Need It

  • Longer Retention: DPA stays in your blood plasma longer than EPA.
  • Anti-Inflammatory: It actively resolves inflammation in the body.
  • Brain Health: Supports cognitive function and mood regulation.
  • Sustainable Source: Algal DPA avoids overfishing and ocean pollutants.

Deep Dive

DPA is a powerhouse nutrient that plays a crucial role in 'resolvins'—compounds that tell your body to stop inflammation after the immune system has done its job. This makes it vital for recovery and joint comfort. Because it is structurally similar to the Omega-3s our bodies are made of, it is easily incorporated into cell membranes. For those on a plant-based diet, DPA bridges the gap, offering a potent Omega-3 that bypasses the inefficient conversion process required by standard flax or chia seeds.

Natural Food Sources

While fatty fish are the most common source, we focus here on plant-based and sustainable origins.

Food SourceAmount (per serving)% Daily Value (Est.)
Algal Oil100-200mg20-40%
Krill Oil50-100mg10-20%
Sea AsparagusTrace amounts<5%
Albacore Tuna50-70mg10-15%

Supplementation

Dosage: There is no official RDI for DPA specifically, but clinical studies suggest 200mg–500mg daily is effective for maintaining blood levels.

Who should take it?

  • Plant-Based Eaters: To ensure adequate Omega-3 intake without fish.
  • Athletes: To speed up recovery and reduce muscle inflammation.
  • Those with High Inflammation: Who may not respond fully to EPA/DHA alone.

Frequently Asked Questions

DPA is not 'better,' but it is different. It acts as a reserve tank in the body, staying in your system longer than the EPA found in fish oil. It also converts more efficiently into anti-inflammatory compounds.
It comes from marine algae (schizochytrium sp.). It is grown in tanks on land, making it 100% vegan and free from ocean contaminants like mercury.
No. Flax seeds contain ALA, which the body must convert to DPA. This conversion is very inefficient (less than 5%). Direct sources like algae or fish are necessary for significant levels.
High-quality algal DPA supplements are usually encapsulated and have no fishy taste or smell.

Safety & Side Effects

Safety & Side Effects

Generally Recognized As Safe (GRAS) at dietary levels.

  • Blood Thinning: High doses (over 3g/day) may increase bleeding time. Use caution if taking blood thinners (Warfarin, Aspirin).
  • Digestive Upset: Mild indigestion or fishy burps (rare with algal versions) can occur if taken on an empty stomach.
  • Allergies: Avoid if you have a severe allergy to seafood or algae.

Always consult your doctor before starting a new supplement regimen.
