Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

The disease, disorder, syndrome, illness, or injury that is being studied.
This is a double-masked, placebo controlled, randomized clinical trial of xanthohumol, which is a constituent of hops (Humulus lupulus). Hops and its constituents have a long history of use for a variety of conditions. However, knowledge is limited regarding the measurable biological markers of human exposure, and the role of xanthohumol metabolism by microorganisms present in the gut, particularly in individuals with gut pathologies such as Crohn's Disease. This information is necessary for the development of xanthohumol as a potential therapeutic intervention in such conditions.
Participants will take capsules containing 24 mg of xanthohumol in a rice protein vehicle by mouth once daily with the first daily meal.
Placebo Comparator: Placebo
Participants will receive capsules filled with a rice protein vehicle by mouth once daily with the first daily meal.
Drug: - Xanthohumol
The xanthohumol supplement will be administered in a capsule and taken orally.
Other: - Placebo
The placebo will be administered in a capsule and taken orally.
