About Stearidonic Acid (SDA)
Stearidonic acid (18:4 n-3) is a plant-derived omega-3 (echium, hemp, some GM soybean oil) that bypasses the rate-limiting delta-6-desaturase step, so it raises EPA in blood more efficiently than ALA does, though far less than direct EPA/DHA. Human trials confirm EPA enrichment but do not establish independent clinical outcomes. Grades low: interesting as a more-convertible plant omega-3, but no standalone efficacy evidence and negligible DHA conversion.
What Stearidonic Acid (SDA) supports
- Converts to EPA more efficiently than ALA, offering a plant omega-3 route, though conversion to DHA is negligible
How much Stearidonic Acid (SDA) to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
0–0
mg
No established therapeutic dose; positioned as a plant omega-3 intermediate. Nominal range for a fatty-acid-profile line item.
Clinical evidence
Limited clinical evidence. Raises EPA better than ALA in trials; no standalone clinical-outcome evidence.
