NCT ID NCT07193264
First seen Jun 27, 2026 · Last updated Jul 07, 2026 · Updated 2 times
Summary
This study looks at how caffeine, the stimulant in coffee and energy drinks, affects blood stem cells in healthy adults. Researchers will compare people who drink caffeine regularly with those who rarely do. All participants will take a single 200 mg caffeine tablet (about one cup of coffee) on an empty stomach, and blood samples will be taken before and three hours after to see if caffeine changes how stem cells move from bone marrow into the blood.
