Omega-3 metabolite put to the test for Post-Meal blood fats
NCT ID NCT05953064
First seen Sep 21, 2026 · Last updated Sep 21, 2026
Summary
Researchers are testing whether DHA-NAT, a substance made in the body from omega-3 fatty acids, can lower blood triglycerides after a high-fat meal. The trial enrolls 20 healthy men aged 18 to 30 with a normal body mass index. In a randomized, double-blind, crossover design, each participant receives DHA-NAT and a placebo on separate occasions, and researchers measure triglyceride levels over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- DHA-NAT, a metabolite of the omega-3 fatty acid DHA
- What this could lead to
- If DHA-NAT lowers post-meal triglycerides, it could point toward a new way to manage blood fat spikes after eating.
- What could go wrong
- This is a small, early study in 20 healthy young men, so results may not apply to other groups. DHA-NAT is experimental and its effects in humans are not yet known.
