bash + break syntax + exit from loop by break n

we build the following loop in bash script

until [[ $completed == true ]]
do
if .....
   then
   echo "procedure ended"
   break # break the for looop
else
   .
   .
fi
.
.
done

we want to exit from the loop , when procedure ended ( see echo "procedure ended" )

we are not sure if we need to set break or break 1 ?
