To Investigate Effects of Amway Bundle Combination of Products on Osteoarthritis & Sarcopenia

Study Overview
=================
Brief Summary
-----------------
The goal of this interventional study is to evaluate the effects of bundle combination of Amway All-plant protein booster with Nutrilite Lifestyle guideline and/or EMS (Electric Muscle Stimulation) device on Osteoarthritis & Sarcopenia in the middle-aged and elderly (50-70 years old) people. 240 eligible participants will be randomly assigned to 4 equal size study groups (ideally 52 for each group will complete the study) in the two study centers in Shanghai, three site visits will be made during the 6 months of study after screening test. All clinical data will be measured /captured on paper CRF(Case Report Form) and then recorded into CTMS(Clinical Trial Data Management System) for analysis and reporting. It's essential that participants should practice with the assigned guideline and device besides taking the products per day. Researchers will compare the four groups to see if there is significant improvement of Amway study products with bundle combination of Nutrilite Lifestyle guideline and/or EMS on Osteoarthritis & Sarcopenia in the participants.
