About this study
Official title: Food Design for Improved Cognitive Performance
This project evaluate effects of a commonly used food supplement on glucose metabolism and cognitive function.
Read the detailed description
The test product has previously been suggested to elicit beneficial effects on glucose metabolism and cognitive performance. The purpose with this study is to evaluate metabolic effects and effects on mood variables of the test product provided at breakfast. Test variables are determined at fating and postprandial a standardised breakfast. The results are compared with effects after a placebo product.
- Conditions
- Postprandial Blood Glucose Regulation
- Being tested
- Panax ginseng, Placebo
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Panax ginsengDietary supplement
Pananx ginseng is provided prior to a standardised breakfast, effects on test variables are determined at fasting and repeatedly postprandially the breakfast
PlaceboDietary supplement
| Study group | Role | What they receive |
|---|---|---|
| test product | Experimental | Arm: Panax ginseng Receives: Dietary Supplement: Panax ginseng |
| placebo product | Placebo comparator | Arm: a placebo with similar appearance but without Panax ginseng. The tablet include all the other non-active bulk ingredients. Receives: Dietary Supplement: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
blood glucose
capillary blood glucose concentrations are determined at fasting and then repeatedly after a standardised breakfast
Measured: 4 hours
Secondary outcomes (2)
serum insulin
capillary serum insulin concentrations are determined at fasting and then repeatedly after a standardised breakfast
Measured: 4 hours
Mood as measured by ratings on 100 mm visual analog scales( VAS rating scales)
measures of 6 mood variables (sad-glad, depressed-happy, displeased-pleased, dull-peppy, passive-Active, sleepy-awake) repeatedly in the postprandial period after breakfast
Measured: 4 hours

Questions about this trial
What is this clinical trial studying?
A study testing Panax ginseng in people with Postprandial Blood Glucose Regulation, run by Lund University at 1 site in Sweden.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Sep 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
blood glucose (time frame: 4 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02392819, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Sep 2015.
