Summary

This completed Phase 1 trial in 48 healthy adults tested whether taking meldonium (a drug) together with omega-3 supplements (EPA and DHA) increases omega-3 levels in the blood more than omega-3 alone. Participants were split into three groups and took different combinations over 8 weeks. The study measured blood levels of omega-3s and related fat metabolites, but did not treat any disease.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Meldonium and omega-3 (EPA/DHA) supplements
What this could lead to
If it works, this could point toward a way to increase omega-3 levels in the blood more efficiently, which may help in conditions linked to low omega-3.
What could go wrong
This is a very early, small study in healthy volunteers, not patients. It only measures blood levels, not health outcomes. Results may not apply to people with diseases.
