Study Details

Study Description

Brief Summary

This study is a randomized, double-blind, placebo-controlled, parallel-controlled trial (14 weeks in total), divided into three periods (screening, treatment, and discontinuation follow-up)

Condition or Disease Intervention/Treatment Phase
  • Dietary Supplement: Vigiis 101 Lactobacillus Capsules
  • Dietary Supplement: Placebo Capsules
N/A

Detailed Description

Subjects meeting the inclusion criteria were randomly assigned to 2 groups (Vigiis 101 lactic acid bacteria: n = 50, placebo: n = 50) in a 1:1 ratio, Block : 4 randomization. Randomization was performed by a research statistician not directly involved in the trial. Researchers and subjects were unaware of treatment groups until data analysis was complete.

During the 12-week use trial, subjects were asked to take Vigiis 101 Lactobacillus capsules or a placebo once a day before breakfast. The subjects were required to maintain a regular lifestyle and recorded daily Vigiis 101 Lactobacillus or placebo consumption, diet and the number of steps walked as a measure of physical activity. Body composition, anthropometric and biochemical measurements were measured at weeks 0, 4, 8, and 12 after consumption initiation. Clinical exams are done every 4 weeks in the hospital. Subjects filled out daily diaries that included questions about study product intake, other food intake, number of bowel movements, stool quality (consistency and color), any medications received, and any uncomfortable symptoms such as diarrhea, constipation, Vomiting, flatulence, discomfort, etc.

(3) Serious violations of the research protocol. (4) Taking drugs that may affect body weight or body fat (such as contraceptives, steroids, female hormones) or functional health food with probiotics in the experiment.

(5) When severe adverse reactions occur clinically. (6) The aforementioned "subject exclusion conditions" did not occur during the screening period, and must be withdrawn if they occur during the trial.

(7) Other situations where continuing to participate in the research will endanger the health of the subject. When there is important new information during the execution of the trial (referring to your rights or affecting your willingness to continue participating), you will be notified and further explained. Please reconsider whether to continue participating. You can decide freely and will not cause any discomfort. Or affect their future physicians to your medical care.
