Abstract
Review of stearidonic acid as a supplemental omega-3 source.
Methodology
Narrative/critical review of human evidence on SDA-rich oils as precursors of long-chain n-3 PUFA
Key Findings
Conversion to EPA is more efficient from SDA than from ALA, and increased SDA intake raises red blood cell EPA, though less than direct EPA supplementation. No trials yet test whether this translates into health outcomes.
Conclusions
SDA-rich oils are a credible plant-based way to raise EPA status, but clinical benefit remains unproven.
Limitations
Narrative review without formal systematic search or meta-analysis; predates the Ahiflower-specific trials.
Supplements Studied
This review discusses the currently available evidence that increased SDA consumption can increase red blood cell EPA content, although this is less than the effect of supplementation directly with EPA.
