First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial tests a dietary supplement called 2-HOBA in 12 adults with pulmonary arterial hypertension (PAH), a condition where high blood pressure in the lungs strains the heart. Participants take the supplement three times daily for 12 weeks. The study checks if 2-HOBA improves heart function and reduces signs of disease, building on earlier positive results.

What this could mean

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

Active substance
2-HOBA (a dietary supplement)
What this could lead to
If it works, this could point toward a new supplement-based treatment to help control pulmonary arterial hypertension and improve heart function.
What could go wrong
This is a very small early-phase trial with only 12 participants, so results may not apply broadly. The supplement's effectiveness and safety are still unproven.
