    Published in Neuropsychobiology

    Methodology

    Randomized crossover comparison of amantadine and L-carnitine, each given for 2 months separated by a washout, in patients meeting chronic fatigue syndrome criteria, using standardized clinical rating parameters.

    Key Findings

    L-carnitine produced statistically significant clinical improvement in 12 of 18 measured parameters in chronic fatigue syndrome, with maximal benefit around 4-8 weeks, while amantadine gave no benefit and was poorly tolerated.

    Conclusions

    L-carnitine produced significant clinical improvement in 12 of 18 parameters; amantadine was poorly tolerated.

    Limitations

    Small sample (n=30), no placebo arm, open crossover design vulnerable to expectancy and carryover, and multiple outcome parameters increasing false-positive risk.

    Supplements Studied

    L-Carnitine
    Amino Acid

    With L-carnitine we found statistically significant clinical improvement in 12 of the 18 studied parameters after 8 weeks of treatment.
