The Claim

In C57BL/6 mice, supplementation with Echium oil and Ahiflower oil increases erythrocyte docosahexaenoic acid (DHA) levels, and erythrocyte DHA levels are higher than DHA levels in plasma, heart, or brain tissues under the same conditions.

In plain English

In C57BL/6 mice, feeding Echium oil or Ahiflower oil raises DHA levels in red blood cells more than in plasma, heart, or brain tissues.

See the scientific wording

In C57BL/6 mice, erythrocyte docosahexaenoic acid (DHA) levels increase with both Echium and Ahiflower oil supplementation, suggesting erythrocytes may serve as a more responsive biomarker for DHA synthesis than plasma, heart, or brain tissues.

Why this might work

The liver converts plant-based fats into DHA and sends it to red blood cells, which take up and hold onto it more effectively than the brain, heart, or blood plasma, making red blood cells a better indicator of DHA production.

1 study

  1. Study: Eicosapentaenoic and Docosahexaenoic Acid Levels in Mouse Tissues After Intake of Echium and Ahiflower Oils Rich in Stearidonic and α‐Linolenic Acids

    When mice ate oils from Echium or Ahiflower plants, their red blood cells showed more DHA, but their brain, heart, and blood plasma didn’t change. This means red blood cells might be better at showing if the body is making more DHA than other parts.
