A Pilot Clinical Trial on the Efficacy of Two Carnitine-Based Products on Muscle Function in Healthy Older Adults

This study evaluates two L-Carnitine-based products on muscle function in healthy older adults (55 to 70 years old). These products are suspected to improve muscle function and possibly promote building of muscle mass. One third of the subjects will be on Carnipure Product 1, one third will be on Carnipure Product 2 and one third will be on placebo.

Primary outcomes

  1. Percent Change in Muscle Function Composite Endpoint from Baseline to Day 57 of subjects administer Carnipure Product 2 versus those administered Placebo

    Time frame: Baseline and Day 57

    A composite endpoint determined by multiplying the values of Lean Body Mass (as assessed by DXA, kg), and functional muscle strength (as assessed by 6 Minute Walk Test, metres; Lower Body Dynamometry, kg; Upper Body Dynamometry, kg). Percent change from baseline to day 57 will be derived.
