Take into consideration is wordy for consider. In most cases, the three-word phrase could be shortened to a single word with no loss of meaning. This is equally true when take and into consideration are separated by the thing being considered. Take under consideration is likewise redundant, though it’s less common.
Examples
In these examples, take into consideration and its variations could be shortened to the one-word consider, considered, or considering:
