NCT ID NCT07486557
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether taking a daily Cistanche deserticola supplement along with moderate aerobic exercise (40 minutes, 3 times a week for 18 weeks) could improve body composition, insulin resistance, and inflammation in men aged 50-55 with central obesity. 125 men were randomly assigned to the combo treatment or usual lifestyle advice. Researchers measured changes in waist size, body fat, muscle mass, blood sugar, and inflammatory markers. The goal is to find a safe, effective way to boost metabolic health in this population.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Cistanche deserticola extract
- What this could lead to
- If it works, this could point toward a natural supplement-plus-exercise approach to help men with central obesity improve metabolic health and reduce inflammation.
- What could go wrong
- This is a small, completed trial with 125 men, so results may not apply to other groups. The supplement may cause mild digestive discomfort, and benefits may be modest.
