Raspberry Ketone Intake Upregulates Circulating FGF21 and Induces Energy Expenditure in Humans

An Early Phase 1 interventional study of Raspberry ketone in Obesity, Diabetes and NAFLD (Nonalcoholic Fatty Liver Disease), sponsored by Nanchang University. Completed at 1 site in China. Open to participants aged 20 Years to 70 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-11-08.

Study summary

To investigate the molecular mechanism of raspberry ketone on regulating obesity, the investigators studied the effect of raspberry ketone intake on FGF21 in plasma.

The age of the volunteers were 18-60 years old, both male and female, without diabetes, hypertension and other diseases.

After ingestion of raspberry ketone (500mg), 2ml of blood was collected at 0 hours, 3 hours and 6 hours , and the FGF21 content in plasma was measured using a commercial reagent kit.

In addition, the investigators also studied the effect of raspberry ketone intake on energy metabolism 0 hours, 0.5 hours, 3 hours and 6 hours after consuming raspberry ketone (500mg).

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2024 to primary completion in May 2024, 4 months.

Of 71 non-industry phase 1 interventional studies under Obesity, half reached primary completion within 48 months of starting (the median), counting those still running; a quarter within 19 and three quarters within 78. This study's 4 months is below that.

Counting every sponsor, half of 328 studies reached it within 11 months; a quarter within 6 and three quarters within 27.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 8, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
