This study did not identify hepatotoxicity and any side effects of galloylated catechin-containing supplements.

(1)Age is between 20 to < 65 years old on the date of consent
(2)LDL-cholesterol level is 159 mg/dL or less, and BMI is < 30
From 184 individuals, we selected 60 (30 allocated to the CAT group and 30 allocated to the placebo group) who fulfilled the inclusion criteria and did not violate any of the exclusion criteria. All subjects completed the study.
A total of 21 adverse events were identified in both groups (CAT; 13 events; placebo; 8 events) during the study period through interviews and examination of subjective and objective symptoms. There were 2 cold-related events with CAT and 2 with placebo, 5 gastrointestinal events with CAT and 3 with placebo, and 1 dental event with CAT and 0 with placebo. The other events were 5 on CAT and 3 on placebo. There was no clear difference in the number of adverse events between the two groups. There were five events graded as 'moderate' for both CAT and placebo, and no events were graded as 'severe'. The principal investigator determined that all events were 'unrelated' or 'probably unrelated' to the study material. Therefore, there were no side effects from CAT.
