One of the most common symptoms experienced by patients undergoing chemotherapy is fatigue. A study that was published in Support Care in Cancer (2016 Feb;24(2):637-46. doi: 10.1007/s00520-015-2824-4. Epub 2015 Jun 24) looked at whether an trademarked amino acid jelly, containing CoQ10 and L-carnitine was effective in controlling fatigue in breast cancer patients undergoing chemotherapy.
Subjects were randomly assigned to receive the amino acid jelly once daily or regular care for 21 days. Of the 59 patients who were enrolled in the study, 57 were included in the analysis. Median patient age was 50 years. Changes in the worst level of fatigue, global fatigue score, and current feeling of fatigue were significantly different between the control group and the group receiving the supplement. The change in the average feeling of fatigue was not significantly different between groups.
