Efficacy of INTOFINE-JOINT SUPPORT DIETARY SUPPLEMENT on Bone and Joint Health

Efficacy and Safety Evaluation of INTOFINE-JOINT SUPPORT DIETARY SUPPLEMENT in Improving Knee Joint Function

The goal of this clinical trial is to evaluate whether INTOFINE-JOINT SUPPORT DIETARY SUPPLEMENT improves joint health in adults aged 40-60 years with mild symptomatic knee osteoarthritis (defined by WOMAC total score 20-32 and knee pain VAS score 2-4). It will also assess the safety of the test product.

The main questions it aims to answer are:

Does the test product relieve knee pain, stiffness and physical activity difficulty measured by the WOMAC Osteoarthritis Index? Does the test product reduce pain intensity evaluated by the VAS Pain Scale? Can the test product improve 6-minute walking distance, sit-to-stand ability, stair-climbing performance and the range of motion of the hip and knee joints? What adverse reactions or safety issues do participants have when taking the test product? This is a single-arm, self-controlled clinical trial. Researchers will compare the test results of participants before and after taking the product to verify its efficacy in improving joint function.

Participants will:

Take 2 capsules of the test product once daily, 1 hour after meals, for 60 consecutive days Complete subjective efficacy evaluations, scale assessments and joint function tests at D3, D5, D14, D30, D40 and D60 Undergo safety follow-up tests of blood glucose, liver function and renal function at D56 Report joint symptoms and provide satisfaction feedback during the trial period

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in WOMAC Osteoarthritis Index Total Score	The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is a 24-item questionnaire that measures knee pain, stiffness, and difficulty with daily activities. Scores range from 0 (no symptoms) to 96 (severe symptoms). The primary endpoint is the change in total score from baseline to the end of the study, to assess overall improvement in knee function.	From baseline (Day 0) to the end of the 60-day intervention period, subjects completed efficacy evaluations at six predefined time points: Day3, Day 5, Day 14, Day 30, Day 40, and Day 60.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Knee Pain Intensity (VAS Score)	Knee pain is measured using a 10-point Visual Analog Scale (VAS), where 0 = no pain and 10 = worst possible pain. Participants rate their pain at rest and during daily activities (e.g., walking, climbing stairs). Changes in these scores from baseline are tracked over the intervention period.	Baseline (day 0), day28 and day 56
6-minute walk test (distance walked in 6 minutes)	The test is conducted in a 20-30 meter flat corridor, with the ambient temperature maintained at 20-25℃ and relative humidity at 40%-60%. Upon instruction, the subject walks continuously for 6 minutes at the maximum tolerable speed. The tester gives a time reminder every minute. If the subject feels significant discomfort, they may rest or terminate the test at any time, and relevant information shall be documented. Once the timing ends, the final position of the subject is recorded, and the total walking distance is calculated. Reporting method:Change from baseline to Day 28 and Day 56, presented as the mean distance, mean change from baseline, and percentage improvement at each time point.	Baseline (day 0), day28 and day 56
Participant Global Assessment of Knee Symptom Improvement	At the end of the study, participants rate their overall knee symptom improvement using a 5-point scale (1 = much worse, 5 = much better). This self-reported measure captures how participants perceive the effect of the intervention on their daily lives.	From baseline (Day 0) to the end of the 60-day intervention period, subjects completed efficacy evaluations at six predefined time points: Day 3, Day 5, Day 14, Day 30, Day 40, and Day 60.
Sit-to-stand test	1.Test Requirements: Subjects complete 3 consecutive stand-sit movements at a uniform speed without external assistance from handrails, walls or other supports. 2.Evaluation Criteria： Excellent: All 3 movements are standard with upright trunk, no body sway or knee pain, and no auxiliary support required.; Good: All 3 movements are basically standard with occasional slight self-adjustable sway, no knee pain, and no auxiliary support required.; Pass: Slight knee soreness or obvious body sway occurs during movements, or 1-2 movements require knee support by hands to complete.; Fail: Unable to complete movements independently, requiring external assistance; or presenting with collapsing sitting posture and obvious lower limb weakness during standing up. 3.Reporting method: Change in sit-to-stand test score from baseline and percentage improvement at each time point.	Baseline(day 0), day28 and day 56
Stair-climbing test	Subjects complete a stair-climbing test on a 30-step staircase (16 cm per step). Performance is scored on a 4-point scale based on knee pain, stability, and functional ability to assess improvements in joint function and mobility. Reporting method:Change in sit-to-stand test score from baseline to Day 56, presented as the mean change and percentage improvement from baseline.	Baseline (day 0), day 28 and day 56
Joint range of motion	Test items: hip external rotation, hip internal rotation, knee flexion and extension Reporting method: Change in hip external rotation, hip internal rotation, knee flexion and extension range of motion (degrees) from baseline to test day, presented as the mean change and percentage improvement from baseline.	Baseline (day 0), day28 and day 56
Changes in liver function parameters	Test items:Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Gamma-Glutamyl Transferase（GGT） Reporting method: Changes in each parameter at baseline and Day 56, as well as the proportion of subjects with values exceeding the upper limit of normal range	Baseline (day 0), Day 56
Changes in renal function parameters	Test items: Urea (UREA), Creatinine (Cr), Uric Acid (UA) Reporting method: Changes of each parameter at baseline and Day 56, and the proportion of subjects with values exceeding the upper limit of normal range.	Baseline (day 0), Day 56
