For fragment [1,3 A - ] ( d,e,f ) and fragment [1,3 A + ] ( g,h,i ) comprising C 4 , the incorporation of an O 18 label is not observed, while fragment [0,2 A-H2O] + ( g,h,i ), including C 3 , contains an O 18 label supporting formation of flavan-3,3,4-triol ( 4 )

Some randomized controlled trials combining topical + oral glutathione observed statistically significant improvements in skin brightness and melanin index around 8 weeks
