Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This randomized, double-blind, controlled clinical trial aims to evaluate the effects of the consumption of orange juice enriched with vitamin D3 and encapsulated probiotics (Lacticaseibacillus casei Shirota and Lacticaseibacillus rhamnosus GG) compared to conventional orange juice in 50 high cardiometabolic risk volunteers. The participants must be overweight/obese with either prediabetes, and/or hypertension, and/or hyperlipidemia, and will be divided and randomly assigned into 2 groups of 25 individuals each. Participants will consume 250 ml of either orange juice enriched with vitamin D3 and encapsulated probiotics (Lacticaseibacillus casei Shirota and Lacticaseibacillus rhamnosus GG) or conventional orange juice daily for 8 weeks as an addition to their usual dietary intake. Participants will be asked to maintain their usual physical activity during the intervention period. At the beginning of the study and at 8 weeks, blood samples will be collected after 12 hours of fasting. Two-hour oral glucose tolerance test (OGTT) will be performed using a continuous glucose monitoring system at the beginning and at 8 weeks. Anthropometric measurements will be performed at the beginning and every week for 8 weeks. Basal metabolic rate (BMR) and central aortic blood pressure will be measured at the beginning, 4 weeks, and 8 weeks of intervention. Fecal samples will be collected and analyzed to study gut microbiome compositob at the intervention's beginning and at 8 weeks.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
