Randomization (investigator's opinion)
Randomized
Randomization description
A person outside the study is asked to randomly assign the letter A or B to the cans of supplement and placebo by flipping a coin, and then hand the cans to the researcher. It is used to randomize patients to receive packages A and B using random number generation software.After analyzing the data, the person outside the study will be requested to provide the names of the drug and placebo labels to be utilized in the results and discussion section.
Blinding (investigator's opinion)
Triple blinded
Blinding description
Supplement and placebo will be categorized based on random codes. The researcher, gastroenterologist, individuals involved in sample evaluation, and the person conducting statistical analysis will be blinded to the intervention or control group assignment.
