This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether vitamin D3 supplements can help improve cardiovascular and metabolic health in teenagers who are overweight or obese. Researchers will give some participants vitamin D3 (a common vitamin supplement) while others receive a placebo (an inactive pill that looks the same), and then measure changes in heart health markers over 12 weeks. The study involves 130 teenagers from schools in China.
Many overweight and obese teenagers have low vitamin D levels and increased risk for heart disease. This trial aims to find out whether this medication could help reduce those risks and improve overall heart health in young people.

If you join, you'll be randomly placed into either the treatment group or the placebo group. For 12 weeks, you'll take a daily capsule—either the vitamin D3 supplement or a placebo that looks identical. You'll visit the research team every 2 weeks for the first 6 weeks, then every 3 weeks for the next 6 weeks, so they can track your health and give you more capsules. At the end, the researchers will measure your cardiovascular and metabolic health to see if the treatment made a difference.
