Health Evaluation of Mushrooms withVitamin D2

January 28, 2023 updated by: Taipei Medical University
Although Taiwan has plenty of sunshine, the intake of vitamin D and the concentration of 25(OH)D in the blood are low. Ingestion of mushrooms and extracts rich in D2 can increase the nutritional source of vitamin D. The purpose of this study is to evaluate the intake of D2 mushrooms and extracts in humans to achieve the effective concentration of 25(OH)D in the serum and recommendations for health improvement.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The subjects were divided into 3 groups: no mushroom intervention, intervention with D2 10ug Pleurotus citrinopileatus after bio-optics optimization (low dose group) or intervention with D2 100ug Pleurotus citrinopileatus after bio-optics optimization (high dose group). The low-dose group took D2 10ug per day, and the high-dose group received D2 100ug per day for a total of 4 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.

Ages Eligible for Study

20 years to 60 years (ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

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
Measure Description
Time Frame
Change from baseline in 25OHD at week 4
Time Frame: Baseline and week 4

The participants' blood was taken to analyze the concentration of 25OHD to compare the changes between baseline and 4 weeks later. 25OHD concentration standard is:

25OHD < 20 ng/ml: deficiency 20 ng/ml < 25OHD < 30 ng/ml: Insufficiency 25OHD > 30 ng/ml: Normal
