       Abstract
       L-carnitine tartrate has been shown to improve relatively
       short-term recovery among athletes. However, there is a lack of
       research on the longer-term effects in the general population.
       Objective: The primary objectives of this randomized
       double-blind, placebo-controlled trial were to evaluate the
       effects of daily L-carnitine tartrate supplementation for 5
       weeks on recovery and fatigue.
       Method: In this study, eighty participants, 21- to 65-years-old,
       were recruited. Participants were split into two groups of forty
       participants each, a placebo, and a L-carnitine Tartrate group.
       Seventy-three participants completed a maintenance exercise
       training program that culminated in a high-volume exercise
       challenge.
       Results: Compared to placebo, L-carnitine tartrate
       supplementation was able to improve perceived recovery and
       soreness (p = 0.021), and lower serum creatine kinase (p =
       0.016). In addition, L-carnitine tartrate supplementation was
       able to blunt declines in strength and power compared to placebo
       following an exercise challenge. Two sub-analyses indicated that
       these results were independent of gender and age. Interestingly,
       serum superoxide dismutase levels increased significantly among
       those supplementing with L-carnitine tartrate.
       Conclusions: These findings agree with previous observations
       among healthy adult subjects and demonstrate that L-carnitine
       tartrate supplementation beyond 35 days is beneficial for
       improving recovery and reducing fatigue following exercise
       across gender and age.
