First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study tested three different doses of a maqui berry extract called Delphinol in 10 healthy adults to see how it affects blood vessel function. Participants took each dose for 8 days, and researchers measured blood flow and related markers. The goal was to find the optimal dose for future research, not to treat any disease.
