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.
