NCT ID NCT01632761
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether taking vitamin D and fish oil supplements can reduce the risk of developing anemia in people aged 60 and older. Researchers are following 2000 participants from a larger heart-health trial who did not have anemia at the start. They will compare anemia rates between those who took the supplements and those who took placebos over two years.

What this could lead to
