About

This study is a randomized, double-blind, placebo-controlled clinical trial designed to evaluate the effects of astragaloside supplementation on joint discomfort in healthy adults. The primary goal is to determine if daily intake of astragaloside can improve knee joint function and reduce discomfort over a 12-week period. Participants will be randomly assigned to receive either an astragaloside capsule or a placebo capsule once daily. Aim to see if those taking astragaloside experience better mobility and fewer joint-related symptoms compared to those in the placebo group.

Full description

The purpose of this randomized, double-blind clinical trial is to investigate the efficacy of astragaloside supplementation in enhancing joint health and physical function among healthy individuals aged 20 to 70 years.

Study Design and Procedures: Participants will be randomized into two groups: the intervention group (astragaloside) and the control group (placebo). Each participant will be instructed to consume one capsule daily after a meal for 12 weeks.

The study aims to address the following objectives:

Physical Function Assessment: To evaluate changes in knee joint mobility and strength using the Single-Leg Step-Down (SLSD) test and Range of Motion (ROM) measurements.

Subjective Symptoms and Quality of Life: To assess improvements in knee-related symptoms through the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire.

Biological Markers: To analyze blood biomarkers related to joint health and systemic response.

Comparative analysis between the astragaloside and placebo groups will be conducted to determine the statistical significance of the supplement's impact on joint function and discomfort.
