Summary

This study looks at whether taking daily vitamin D and omega-3 (fish oil) supplements can help prevent high blood pressure or lower it in healthy adults. Over 25,000 people are taking part, with a smaller group having their blood pressure monitored around the clock. The goal is to see if these common supplements make a real difference for heart health.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Vitamin D3 (cholecalciferol) and omega-3 fatty acids (fish oil)
What this could lead to
If it works, this could show that simple, affordable supplements help manage blood pressure and reduce the risk of hypertension.
What could go wrong
This is an observational analysis within a larger trial, not a dedicated treatment study. Results may be modest or not apply to everyone.
