Could a daily dose of lutein boost kids' brainpower?
NCT ID NCT05177679
First seen Jul 27, 2026 · Last updated Jul 28, 2026 · Updated 1 time
Summary
This trial tests whether giving children aged 8–10 a daily supplement of lutein and zeaxanthin — nutrients found in leafy greens and eggs — can improve their attention, memory, and academic achievement over a school year. Half the children receive the supplement, while the other half receive a placebo. Researchers will measure changes in cognitive tasks, school test scores, and a marker of eye health called macular pigment optical density.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- a daily supplement containing 10 mg lutein and 2 mg zeaxanthin
- What this could lead to
- If it works, this could point toward a simple dietary supplement to help sharpen attention, memory, and academic performance in school-age children.
- What could go wrong
- This is a relatively small, early-stage trial in healthy children, so results may not apply broadly. The supplement is generally safe, but any cognitive benefits may be modest or absent.
